I build software.
From zero to shipped.
I build, ship, and write about software products: from SaaS to AI-powered pipelines and mobile apps.

Field Notes
What I am learning
while building.
An engineer's notebook. Specific, practical, and honest.
About Me
Building products,
not pitches.
Software has always been a way to build things and put them in front of people. Over the years that has meant my own products, client work at an AI consultancy, marketplaces, mobile apps, AI pipelines. Some things reached users in 9 countries. Others taught me more by failing than by succeeding. The common thread is that things tend to get to production.
My stack centres on TypeScript, React, Next.js, and PostgreSQL. AI is genuinely woven into how I build now: not as a finishing touch, but as a practical layer in pipelines, background jobs, and user-facing features. I reach for it where it simplifies something that would otherwise be hard.
What I enjoy most is the full arc of a product: the early decisions that are hard to undo, the messy build phase, and eventually watching someone use the thing you made. That last part never gets old.
Open to Work
Let's talk if you are
building something real.
I am currently looking for full-time product/software engineering roles where shipping, product judgment, and AI-assisted workflows matter.
