1- Update application calls should have zero delay so that calls go at full speed. 2- Latency is very important — locally it's 250-300ms, so after deploying on AWS it should be minimum 200ms. So delay = 0 and latency should be low so calls hit fast. 3- We need to pick jobs, and for that we need to eliminate 429, 403, and 504 errors. Why does 429 come? Because we reuse the same token too fast. 403 comes when multiple calls hit from the same IP or combination calls hit together. 504 doesn't come that often, so for that we can keep a retry mechanism. 4- To eliminate 429, we need to use multiple tokens, because a job will only be picked when calls go without even a single 429, with latency 200-250ms and delay 0. 5- For that, we need to do the following: Enter one combination of job ID + sch ID, and its location code (which will come from the sch ID response) and application ID (which will come from create application). We'll add those two manually. Then what will happen — with the help of auto-create, accounts will keep getting created continuously until all accounts are created. Like if I enter 200, it will create 200 accounts. 6- What will the pipeline do? If I start the pipeline, it will log in to all created accounts and add them to a pool. Like if I enter 300, it will log in to 300 accounts. But when it logs in, the "create application" and websocket calls will already have been hit. 7- Now what happens: Whenever I see 30-40 accounts in the pool as logged in, I'll start — it will start from candidate 1 and directly fire update application calls (which I've set to 5 seconds), so it will call for 5 seconds and then switch to candidate 2. But candidate 1 will only be "burned"/released when candidate 2's update application calls have started, and candidate 1 will be added back to the pool (but at the back). 8- So candidates always switch like 2→3→4→5→6... if it reaches 200, it starts again from 1. And make sure no job is missed during candidate switching — a candidate should not be burned/released until the next candidate's calls have started. 9- Now, every combination will have a different email, first name, last name, PIN, IMAP user email, IMAP password, and phone number — all random (random: true). But if a random phone number turns out to be invalid or already registered, it won't create the account — so in that case, it should pick a new random number and keep trying until the account is created. All of this is needed when the account is being created, and each combination must have its own separate .[login to view URL] file. 10- Whenever an update application call goes out, it should immediately go to "fetch for slot" and then "slot book." The booking logic should pick the earliest available slot first, but if that slot was already taken by someone else, it should pick any other available slot and book it. 11- Each combination should run in a separate instance, and the instance should be the largest available — the one with 192 CPUs. 12- Whenever an interview is booked, a Telegram message should immediately arrive containing: Job ID, Sch ID, Location Name, and Email ID — so I can manually log in and check. 13- The same process should work for every combination — the same cycle. 14- We are using residential IPs and assigning a static IP to each candidate, but maybe that's causing latency issues — not sure. 15- All logs should be visible — like: total 429s received, latency of each call, and how fast calls are going. This should run continuously and never close until I manually stop it.

With your Application Optimization and Error Elimination project, I would love the opportunity to put my 15+ years of experience to work for you. My services in API Development and Database Management aligns perfectly with your project needs. In particular, for achieving zero delay in application calls, I'm confident about tuning your existing architecture for enhanced performance. Additionally, I can employ my network security services to address the errors you mentioned — 429s due to token overuse and handling multiple calls from the same IP or combination. My solutions would involve implementing a token rotation strategy, IP throttling, and improved exception handling to significantly minimize these issues. To ensure smooth logging in and account creation, my services in websockets would expedite these actions. And since this project revolves around managing multiple instances and ensuring continuous monitoring/logging, my understanding of DevOps tools like Docker and CI/CD will come in handy. Together, we can achieve not only the slimmer latency locally (200-250ms) but also seamless functioning across cloud platforms like AWS.

Interesting project, I will build the token-rotation and candidate-pool pipeline on AWS — zero-delay update calls, multi-token 429 elimination, and automatic candidate switching with overlap so no job is missed during transitions. For latency, I will place instances in the region closest to the target API and use connection keep-alive with pre-warmed sockets — this alone often cuts 50-80ms versus cold requests. Residential proxy assignment per candidate will stay, but I will benchmark direct vs proxy to isolate the latency source. Questions: 1) Which AWS region are you currently deploying to, and where is the target API hosted? 2) How many combinations do you plan to run simultaneously across instances? Looking forward to talking through the details. Kamran

Hi there, I have thoroughly reviewed your requirement around high-speed job picking, multi-account pipeline, and handling 429/403/latency issues with continuous execution. I can help you build a system where multiple accounts are managed in a pool, calls run with near-zero delay, and latency is kept low using proper rotation and parallel execution. My approach will be to first set up a multi-instance architecture where each combination runs independently, then build the account auto-creation and login pipeline to maintain a ready pool of active candidates. After that, I will implement the rotation logic where candidates continuously fire update calls in sequence without gaps, ensuring no job is missed during switching, along with retry handling for 504 and intelligent token usage to eliminate 429/403. I will also integrate real-time logging, latency tracking, and Telegram alerts for instant booking notifications, keeping the system running continuously on high-performance servers. I would request to connect once so we can align on API behavior and I can structure this for maximum speed and stability. Thanks, Rahul A.

Hi I can build a high-performance backend pipeline focused on low latency, resilient worker orchestration, detailed logging, and continuous execution for approved API workflows. The main challenge in systems like this is achieving speed without creating fragile concurrency, silent failures, or poor visibility, so I would solve that with queue-based workers, controlled retries, per-instance isolation, and full observability. My approach would include long-running workers on AWS, structured configs per workflow, Telegram alerts for successful events, dashboards/logs for latency and error tracking, and safe restart behavior for continuous operation. I can also help identify infrastructure bottlenecks such as IP routing, instance locality, or network overhead that may affect latency. I have experience with backend automation, low-latency services, observability, and resilient job-processing systems where stability matters as much as speed. Thanks, Hercules

@devendrathakur12

i’ve done very similar recently, building high-throughput pipelines with token pools, rotating IPs, and low-latency async calls on AWS. Are you currently using async (aiohttp/httpx) with connection pooling or simple sequential requests? How are tokens and IPs mapped today, one token per IP or shared pools? I suggest using an async worker queue with per-token rate buckets because it avoids 429 bursts while keeping throughput high. I also suggest pinning each account to a sticky residential IP with keep-alive sessions to reduce 403 and latency spikes. I will design a token+account pool manager, implement async call engine with retries and backoff, and handle candidate rotation safely. Then I will add slot booking logic, Telegram alerts, and detailed metrics (latency, 429/403 counts), followed by AWS deployment tuning. Best, Dev S.

Hi, I understand you need a high-performance, zero-delay calling system that rotates multiple accounts/tokens to avoid 429/403 errors, maintains low latency (~200ms), and continuously cycles candidates while handling account creation, login pooling, slot booking, and real-time notifications. The system must be stable, fast, and capable of running at scale across multiple combinations without missing any job during switching. I will design a concurrent pipeline using async workers and queue-based scheduling, where each combination runs in its own isolated instance. It will manage token rotation, IP distribution, and candidate pooling to prevent rate limits, while ensuring seamless switching (no release until the next candidate starts). I’ll implement automated account creation with retry logic (for phone/email issues), real-time slot fetching + booking logic, and detailed logging (latency, 429/403 counts, throughput). Telegram alerts will be triggered instantly on successful bookings. The system will be optimized for AWS high-CPU instances and tuned for minimal latency. You’ll receive a fully automated, continuously running system with account pool management, zero-delay execution, smart retries, detailed logs, and real-time alerts, along with clear setup instructions so you can control and scale it easily.

This isn’t just deployment—you need a high-speed, low-latency execution system with controlled concurrency, token rotation, and intelligent retry handling. I can design a multi-instance AWS setup (high-CPU EC2 or ECS) with account pools, rotating tokens/IPs, and zero-delay parallel calls while minimizing 429/403 errors. I’ll implement a queue-based pipeline with safe candidate switching, retry logic for 504s, and continuous execution. Logging will track latency, error rates, and throughput in real time. Telegram alerts will trigger instantly on booking events. Before starting, I’d clarify rate limits, API behavior, and IP strategy—because that’s where this system will succeed or fail.

With over a decade of experience in full stack development and a deep understanding of AWS and application optimization. I am eager to dive into your project and ensure that your application calls not only go at full speed but with minimal latency. Latency is a crucial aspect, and I've successfully reduced latencies to enhance overall system performance on various projects. Bearing this in mind, I will endeavor to minimize latencies even further during the AWS deployment process, striving for an average of 200ms latency after deployment Additionally, my proficiency in Java allows me to effectively create instances where each combination runs separately, optimizing their performance by allocating them the largest available instance ensuring swift serverless operations. Moving forward with the second part concerning logging and tracking performance - My skill set steers me towards building neat and meticulous logging modules providing real-time visibility; such as total 429s received; latency details of each call; the quickness at which calls are being processed; helping you identify problem areas that need immediate attention.

Hey, I can start now. ✅ I’ve worked on something very similar. Ensuring zero delay and low latency for application calls on AWS is crucial. The challenge lies in handling errors like 429, 403, and 504 effectively. By implementing multiple tokens to prevent 429 errors and setting up a retry mechanism for 504 errors, we can optimize the process. Additionally, running each combination in a separate instance with proper logging and monitoring will be key. Let's chat more details. -Alex

Hello, We are a small, senior AWS and Java engineering team that has built ultra‑low‑latency pipelines where sub‑200ms calls, zero artificial delay, and strict error budgets were mandatory. We can redesign your current flow with multi‑token orchestration, 192‑vCPU instances per combination, resilient 429/403/504 handling, and continuous auto‑account creation with separate config per combo, while preserving pool rotation rules so no job is missed during candidate switching. We will also implement centralized observability (per‑call latency, 429 counts, pool status) and instant Telegram alerts on every successful slot booking. Could you share your current architecture (Java version, frameworks, queueing mechanism, proxy/IP provider, and where latency is currently measured)? Regards Sahanaj
