Professional Overview

I bridge product requirements, business workflows, and engineering to build software systems that work in the real world.

I'm Zisanur Haque, a Technical Product Architect and Product Engineer focused on turning complex business workflows, data, and product requirements into production-ready software systems.

Over the past 4+ years, I've worked across business platforms, marketplaces, CMS products, data-driven applications, and automation systems for teams in the UK and North America.

My approach sits between product thinking and engineering execution. I work through the underlying workflow and data model first, then translate those requirements into practical architecture, APIs, interfaces, integrations, and production systems.

I care about building software that is not only technically sound, but also useful to the people and businesses operating it. That means balancing delivery speed, maintainability, scalability, and real-world business requirements rather than optimizing for technology alone.

I also share engineering ideas, technical explorations, and notes on my blog.

What I Bring

  • 4+ years building and shipping production-grade software systems
  • Business platforms, marketplaces, data systems, and automation workflows
  • Full-stack engineering across Next.js, TypeScript, Python, FastAPI, Django, and PostgreSQL
  • Experience translating product requirements and business workflows into scalable technical systems
