What I'm looking for

I’m looking for a fully remote role where I can own production systems end-to-end—FastAPI/React or Next.js plus OpenAI/LangChain-style AI—while building scalable event-driven pipelines with Kafka and AWS.

I build end-to-end systems that mix Python backends, MERN-style frontends, and LLM-powered features—most recently at TechAlliance (remote), where I architected an async FastAPI + React/Next.js SaaS.

I delivered 100K+ MAU with 99.95% uptime, improved Next.js SSR Core Web Vitals and SEO by 35%, and kept RAG responses under 200ms by wiring OpenAI GPT-4o with LangChain, Qdrant, and hybrid retrieval.

I also designed event-driven pipelines with Kafka + Celery for real-time AI classification and anomaly detection (1M+ events/day), then added LangGraph multi-agent orchestration and LoRA/QLoRA fine-tuning to boost extraction accuracy by 28%.

Earlier at Logic Vortex (remote), I shipped Django 4.x + DRF APIs and React/Node experiences for 80K+ monthly users, refactored to async ASGI for a 35% p95 response-time cut, and built ML models (scikit-learn/XGBoost) served via FastAPI.
