About

I build B2B and B2C products with strong product ownership, a bias for clarity, and a high bar for execution. My sweet spot is turning messy business workflows into smooth, thoughtful software that teams and customers actually enjoy using.

What I enjoy most today is working close to users, understanding the domain deeply, and using AI-assisted execution and internal automation to move faster without lowering quality. I am at my best in small, ambitious teams where engineering is expected to shape the product, not just ship tickets.

Selected work

A technical view of my work: keeping codebases understandable, improving delivery workflows, and shipping reliably in complex product environments.

Freelance for a large operational platform Since Sep 2025

Current freelance B2B mission

Freelance Senior Product Engineer

AI workflows

Raised the bar on CI and team-level delivery confidence across a complex platform.

Ecair

Founding Software Engineer

2024 - 2025

Worked inside a strongly typed monorepo with shared contracts, RFC-driven decisions, and preview environments already in place.

Contributed to the app itself through frontend components, feature work, notifications, and messaging flows.

Built on top of an already strong engineering setup rather than creating the monorepo or CI from scratch.

A strong product codebase that kept moving quickly while I added real user-facing and operational features.

Worked across a modern frontend stack spanning customer flows, internal tooling, and shared UI patterns.
