# Hasib Ahmad Bhuyan

> Backend Engineer and Tech Lead specialising in scalable API platforms, microservices, and production-grade agentic AI systems. I build multi-agent workflows, LLM orchestration pipelines, and RAG-powered tools that turn AI capabilities into real business automation — in Python (Django, FastAPI) and Go (Fiber). I integrate and self-host open-source AI infrastructure, including local Hermes LLM deployments, into production social and marketing automation. I lead cross-functional teams, own architecture decisions, and ship at speed.

## Capabilities

- **LLM orchestration & multi-agent systems** — Agent workflows that survive contact with production — LLM orchestration and chaining, autonomous task decomposition, supervisor–worker routing, structured output parsing, and human-in-the-loop checkpoints.
- **RAG pipelines & vector search** — Retrieval that returns the right context — embeddings, semantic chunking, hybrid retrieval and re-ranking over FAISS, Pinecone, Milvus, and Qdrant, wired into RAG-powered tools.
- **Backend & API platforms** — Maintainable, production-ready services that scale — Python (Django, FastAPI) and Go (Fiber), microservices, Celery task queues, async I/O, on PostgreSQL and Redis.
- **Local AI & automation** — Self-hosted, open-source AI in production — local Hermes Agent (Nous Research) deployments wired into social and marketing automation through scheduling and API integration layers.

## Selected work

- [Oppora.ai](https://hasib.tech/work/oppora-ai.md) (2025—26, AI Sales Automation): An AI-powered sales-automation SaaS built with Django and FastAPI — intelligent automation workflows, multi-model LLM integrations, and production backend services that turn outbound into a system you operate.
- [Heimdall](https://hasib.tech/work/heimdall.md) (2025—26, AI Marketing Automation): An end-to-end AI marketing-automation platform — research, planning, and execution driven by agentic multi-step workflows, with humans staying in control of what actually ships.
- [SailorSearch](https://hasib.tech/work/sailor-search.md) (2025—26, AI Search): A search API designed for agents, RAG pipelines, and deep research — it returns clean markdown with enrichment, token compression, and source-aware outputs, so agents get dense, attributable context instead of raw HTML.
- [Production Tracking System](https://hasib.tech/work/protrac.md) (2025, Real-Time Systems): A real-time production-monitoring system with predictive analytics and automated bottleneck detection — replacing day-late manual reporting with live signals for operational and management teams.
- [AI Interview Agent](https://hasib.tech/work/interview-agent.md) (2025—26, Conversational AI): A conversational AI system for interview simulation — it runs a live interview and returns real-time structured scoring and feedback, turning an open-ended conversation into measurable, comparable signal.
