What I Do
Fractional Technical PM
Bridge the gap between product strategy and engineering execution. I own PRDs, roadmaps, and delivery velocity for seed and growth-stage startups.
- PRD & Spec Writing
- Sprint Velocity & Backlog
- Stakeholder Alignment
Rapid MVP Development
Turn ideas into working production apps fast. Complete zero-to-one engineering stack using Next.js, FastAPI, PostgreSQL, and modern UI frameworks.
- Full-Stack Architecture
- PostgreSQL & API Setup
- Vercel / Cloud Run Deploy
AI Feature Integration
Embed intelligence into existing products using Gemini, Claude, or OpenAI. Context engineering, RAG pipelines, and agentic workflows.
- Prompt Engineering & RAG
- Gemini & Claude SDKs
- Production Safety Guards
Industrial Engineering Systems Mindset
My background is Industrial & Production Engineering from MIST (Dhaka). Instead of jumping straight into code syntax, industrial engineering trains you to analyze bottlenecks, workflow friction, and data pipelines first.
When a product underperforms, it is rarely just a UI issue — it is usually a systems bottleneck, an unoptimized query, or a workflow that fights user intent. I apply systems optimization to software product management.
Client Partnerships
Who I Work With
Early-Stage SaaS Founders
Pre-seed and seed-funded startups that need senior product leadership without a full-time PM hire. I convert fuzzy ideas into concrete roadmaps and production releases.
International Agencies
US, UK, and EU agencies that win client contracts faster than they can staff. I serve as embedded Product Engineer and senior technical lead.
Established B2B Teams
Companies introducing LLMs or AI automation into existing software stacks without breaking existing user workflows or security policies.
