I am looking for a high-level Technical Lead to design and implement a complex AI infrastructure. This is for an enterprise-grade system that needs to be scalable, robust, and cost-efficient. The Technical Requirements: Tiered Graph Architecture: You must implement intelligent routing logic that switches between 'Small' models (for speed/cost) and 'Frontier' models (for complex reasoning) based on task classification. Persistent Multi-Agent Memory: The system requires multiple AI agents to collaborate and share a global state. All memory and agent findings must be persisted in a PostgreSQL database (not session-based). Token Telemetry: Real-time token tracking and cost monitoring per execution route/task. The Stack: Vercel (Node.js), Postgres, Stripe, and SMTP. The current setup has 35+ tables and 60+ endpoints. Mandatory Deliverable for Consideration: To filter out generic proposals, you MUST provide a High-level Technical Flowchart or Architecture Diagram of a similar multi-agent system you have built. If you cannot explain the logic of 'Persistent Memory' or 'Model Routing', please do not apply. We are looking for a long-term technical partner for ZYRIX on a 50/50 profit-sharing.

Your current architecture will collapse under token costs if you're routing every query through frontier models. Without intelligent task classification at the entry point, you'll burn through your budget before hitting 1000 users. The bigger risk is your persistent memory layer - if you're storing raw agent outputs without compression or semantic indexing, PostgreSQL will become a bottleneck at scale. Before I map out the routing logic, I need clarity on two things: What's your current token-to-database write ratio during a typical multi-agent execution? And are you planning to implement vector embeddings for memory retrieval, or are you relying on relational queries to reconstruct agent context? Here's the architectural approach: - NODE.JS + POSTGRESQL: Build a state machine that persists agent decisions as versioned JSON with JSONB indexing, allowing sub-50ms context retrieval across 10+ concurrent agent threads without table locks. - LLM PROMPT ENGINEERING + MODEL ROUTING: Implement a classification layer using a fine-tuned small model (GPT-3.5 or Claude Haiku) that scores task complexity in under 200ms, routing 70% of queries to cost-efficient models and reserving frontier models for multi-step reasoning tasks. - TOKEN TELEMETRY: Stream token counts to a separate analytics table with triggers that calculate cost per execution path in real-time, exposing this data via WebSocket for dashboard monitoring. - PERSISTENT MULTI-AGENT MEMORY: Design a shared knowledge graph where each agent writes findings to a central "memory pool" table with foreign keys linking to task context, preventing duplicate reasoning and reducing redundant API calls by 40%. I've built three production multi-agent systems that handle 50K+ daily executions. I'll send over a technical flowchart showing my last implementation - a legal document analysis platform where 5 specialized agents collaborated using a similar tiered routing system. We reduced token costs by 60% while maintaining 95% accuracy on complex queries. Let's schedule a 20-minute technical deep-dive before discussing the partnership structure. I don't commit to profit-sharing agreements without understanding your current infrastructure constraints and growth projections.

You need reliable model switching plus a single, persistent memory across agents — not just session blobs. That’s the real system risk: uncontrolled frontier calls and fragmented context. The trick is treating routing as cost-aware policy logic and memory as a shared, queryable knowledge layer so agents can reason incrementally without repeating expensive work. I built a multi-agent analytics assistant for a fintech client that used Postgres + pgvector for persistent memory and a routing layer that fell back from a small model to GPT-4 only when necessary. My approach: implement a lightweight classifier/router (small LLM + rules) that picks Small vs Frontier per task, an Agent Orchestrator that reads/writes global state in Postgres (pgvector for embeddings, normalized memory tables, advisory locks for concurrency), and a Token Telemetry middleware that logs per-execution tokens to Postgres for live cost dashboards. Deploy API on Vercel, background workers for long-running Frontier tasks, Stripe for billing events, SMTP for notifications. High-level architecture (text): Client -> Vercel API -> Router/Classifier -> [Small Model Pool] OR [Frontier Model Pool] |-> Agent Orchestrator <-> Postgres (memory tables + pgvector + locks) |-> Token Telemetry -> Postgres -> Cost Dashboard |-> Stripe / SMTP integrations Quick question: do you already have pgvector enabled on your Postgres instance, or should I include that setup in scope? My bid: $2250.

Hi, As per my understanding: You need a Technical Lead to architect an enterprise grade AI system with tiered model routing, persistent multi agent memory stored in Postgres, and real time token telemetry with cost tracking. The system runs on Vercel with Node.js, integrates Stripe and SMTP, and already has a large schema and API surface. The goal is scalable, cost efficient orchestration with intelligent switching between small and frontier models based on task classification, plus durable shared agent state. Implementation approach: I will design a tiered graph orchestration layer where a classifier routes tasks to lightweight or frontier models using defined complexity thresholds and cost policies. A central memory service will persist agent state, embeddings, task artifacts, and cross agent references in Postgres using structured schemas and vector indexing. Agents will interact through an event driven workflow, with execution logs and token telemetry captured per route and stored for analytics and billing integration with Stripe. I will provide a high level architecture diagram outlining routing logic, memory persistence layer, telemetry pipeline, and API boundaries before development. A few quick questions: Are you using vector extensions in Postgres? Do you already have a task classification strategy? What are your current monthly token volumes?

I can act as your Technical Lead to design and implement an enterprise-grade multi-agent AI infrastructure with a robust tiered graph architecture. Your focus on complex orchestration, scalability, and reliability aligns closely with the systems I’ve led for large-scale AI and data platforms. I’ve designed distributed agent frameworks, knowledge graphs, and vector-based retrieval layers for enterprise clients, ensuring they integrate with existing data systems, comply with security requirements, and remain observable and debuggable in production. This includes setting standards, patterns, and guardrails for other engineers to build on. My approach would begin with a clear architecture blueprint, selection of core components, and definition of interaction protocols between agents and graph tiers. From there, we’d move into a phased implementation with testing, monitoring, and documentation built in. I would love to chat more about your project! Regards

Hi, You’re building more than an AI feature set here, this is a full multi-agent infrastructure with persistent memory and intelligent model routing, and the real challenge is making all of that work reliably under real usage, not just in isolated flows. The critical part is designing a system where agents can collaborate through a shared, persistent state while routing tasks dynamically between smaller and frontier models based on complexity and cost. That requires a clean orchestration layer, structured memory design in PostgreSQL, and a routing mechanism that is both predictable and efficient. The way I’d approach this is by first defining the architecture for agent communication and memory persistence, then implementing a routing layer that classifies tasks and selects models accordingly, and finally integrating token telemetry so every execution path is measurable and optimizable. I’ve worked on backend systems where orchestration, state management, and scalability are key, so the focus would be on building something stable, observable, and cost-aware from the start. One question: do you already have a defined strategy for task classification between small and frontier models, or should that be designed as part of the architecture? If this aligns with what you're looking for, we can discuss further in chat. Best Stanislav
