AI
Engineer

Hi, I'm Md Shihab Hossain. I build AI systems (RAG, agents, LLM workflows), and the GTM automations that turn them into pipeline.

Things I've built and shipped

Two are open source with live demos. Happy to walk through the private one on a call.

RAG · Open source GitHub stars for Cogniflow AI

Cogniflow AI

Ask your videos, podcasts and PDFs. Get cited answers.

Retrieval-augmented generation that runs in your browser. Add YouTube links, podcasts, PDFs or notes; every claim in the answer carries a citation that links back to the source, and for YouTube to the exact second.

  • Local-first: sources, chunks and embeddings live in IndexedDB; only small excerpts go to the model.
  • Retrieval that holds up: paragraph-aware chunking with overlap, task-typed embeddings, top-k cosine search.
  • Honest refusal: if the sources don't contain the answer, it says so instead of inventing one.

Real-time + AI · Open source DevChat CI status

DevChat

Team chat for developers, with AI code explanations in the thread.

Share code in a channel, get it highlighted properly, and click Explain to stream an AI breakdown under the snippet. No custom backend: the browser talks to Supabase directly and Postgres row-level security is the authorization layer.

  • Security tested, not assumed: 37 allowed and forbidden actions run against the real database's RLS policies.
  • Realtime without a socket server: Postgres change feeds, presence and typing, with backfill after reconnects.
  • Bring your own key, safely: OpenAI keys encrypted with AES-256-GCM, never sent back to the browser.
  • One-click guest demo: anonymous auth, cleaned up after 24 hours by a database cron job.

Outbound Engine

Research and first drafts, done before you sit down.

Webhook- and cron-driven prospecting pipeline: pulls prospect and company data via Apify, summarises recent company news with OpenAI, drafts a personalised first line for each person, and pushes qualified leads to the CRM.

  • End to end: sourcing, research, drafting and CRM sync in one pipeline.
  • Validated at every stage with Pydantic, and a PostgreSQL log of every run.
  • Human stays in control: drafts land for review, nothing is sent automatically.

  • Voice

    voice-booking-agent

    Voice agent using ElevenLabs and OpenAI function calling to check Google Calendar availability and book appointments, logged to Postgres.

  • Finance · Ops
