Nexus Corporation
Nexus Corporation builds autonomous AI agents for Fortune 500 supply chains. I was hired to rip out their slow, hallucination-prone LangChain wrappers and build a deterministic, sub-second latency agentic orchestration engine from scratch.
RAG Pipeline
RBAC Auth Service
Async Standup
Reading Slack threads. I avoid synchronous morning meetings to preserve deep work windows.
Architecture Drafting
Writing RFCs (Request for Comments) for the new embedding model migration. No code is written without a peer-reviewed plan.
Execution
Translating the RFC into Python. Building the Qdrant ingestion worker.
Load Testing
Using Locust to hammer the new worker with 10k concurrent requests to find breaking points.
LangChain is great for prototypes, but custom orchestration is required for production reliability.
Never trust an LLM to output valid JSON without strict Pydantic validation and retry logic in the loop.
DataFlow Inc
DataFlow processed millions of micro-transactions daily. When I joined, their monolithic Node.js backend was falling over during peak trading hours. I led the migration to a microservices architecture.
Event Streaming
Database Sharding
Datadog Review
Checking error rates and latency spikes from the European market session.
Pair Programming
Working with junior engineers to untangle legacy monolithic controllers.
Migration Coding
Writing the Kafka producers for the new event-driven architecture.
Canary Deployment
Routing 5% of production traffic to the new microservice and monitoring logs.
Microservices don't solve bad code, they just distribute it. Fix the domain logic before splitting the monolith.
Always have a one-click rollback plan for database migrations.
TechNova
My first taste of production engineering. I was tasked with building an internal dashboard to track fleet vehicles in real-time, learning how to handle raw WebSockets and messy geospatial data.
Real-Time Telemetry
Route Optimization
Mentor Sync
Reviewing yesterday's code and asking questions about JavaScript closures.
Frontend Hacking
Struggling with React state management to make the map markers move smoothly.
Backend Setup
Writing Express routes and learning how to use Postman to test them.
Code Review
Getting my PR shredded by the senior dev, learning more in 30 minutes than in 3 years of college.
Indexes matter. A missing index will take down your entire application.
