Senior Full-Stack Engineer (Python/RPA) for Logistics SaaS

@devendrathakur12

Hello, I specialize in data extraction pipelines and built and customized large scale RPA ingestion engines using Playwright with Celery and Redis for async processing. The main challenge here is maintaining persistent authenticated sessions on the TIREA portal without triggering rate limits or session drops during continuous polling. I am certified in FastAPI and Playwright development and I will solve this by building a smart polling worker with session reuse, fingerprint rotation and exponential backoff strategies. Few things I need to understand. Does TIREA load content dynamically through websockets or standard HTTP calls? How many service assignments come through daily on average? For the WhatsApp bot via Evolution API, do you already have the instance self hosted or is that part of the scope too? This clarity will help me structure the sprint plan accurately for your MVP. Best regards, Dev S.

@zhens2

As an experienced Senior Full-Stack Developer, I have successfully built and delivered numerous end-to-end web and software solutions using technologies similar to the ones you outlined in your project requirements. I am highly proficient in Python, especially with complex data engineering tasks such as web scraping that will be vital for this project. My skillset includes working with PostgreSQL and even its geospatial extension, PostGIS, ensuring I am adept at efficiently navigating large datasets. I understand the unique challenge your project presents; extracting real-time data from a legacy third-party platform without a public API. I have successfully tackled similar hurdles by leveraging asynchronous task queues like Celery and headless browsers like Playwright - precisely the tools you need. This would enable me to build a performant scraping engine capable of capturing essential data from TIREA while minimizing load on the system. Most importantly, I am no stranger to SaaS platforms having built them from scratch several times. I have experience in crafting high-performance architectures and understand the need for efficient backend systems as well as dynamic user interfaces - making me a perfect fit for your operational hub's MVP as well as the Next.js-based frontend. With deep passion and dedication, I assure you of a top-notch implementation aligned with your vision for Promobilis. Looking forward to hearing from you soon!

⏱ Timeline: 21 days | Cost: €1500 | Proven experience I’ve successfully completed similar projects, specifically building SaaS backends with FastAPI, Celery/Redis workers, and Playwright-based RPA ingestion pipelines, and can provide relevant examples of my work. I’m confident I can deliver the full MVP ingestion engine, dashboard, and WhatsApp automation within 21 days. Based on my past experience, the real challenge is maintaining persistent authenticated Playwright sessions without triggering anti-bot protection while running continuous smart polling. If session reuse, fingerprinting, and task queue isolation aren’t designed properly, the scraper becomes unstable. In a previous insurance-portal automation project, implementing rotating context isolation and Redis-backed state tracking ensured 24/7 reliability without account locks. To proceed, I’ll need staging access to TIREA, expected polling frequency, hosting preference (Docker/K8s/VPS), and confirmation on Evolution API deployment environment. I also confirm full IP transfer and clean repository handover. This is a straightforward project for me, and I’m confident in delivering a robust, production-ready SaaS MVP with secure RPA ingestion. I’m ready to collaborate and start immediately — let’s make this happen.
