01The workshop

Software craftsman · Senior engineer · Since 2011

I shape product ideas and team workflows into software built to last.

Interfaces, internal tools, automation, and AI-assisted processes, made with attention to product feel, maintainable code, and everyday usability.

02The process

I build things that don't get in the way.

I have been building software since 2011, across product, architecture, and implementation details, with a bias toward tools that are clear, fast, and easy to maintain.

The craftsman
  1. 01

    Raw material

    Every build starts with the product and the people using it: the idea, the team's real workflow, and what has to get easier.

  2. 02

    Architecture

    Designing the system before the first weld: services, data, and clear boundaries, so it stays easy to maintain.

  3. 03

    Build & weld

    Backend services and interfaces, joined into one product. AI-assisted by default, to shorten feedback loops and get from idea to working software quickly.

  4. 04

    Temper & test

    Delivery, monitoring, and observability, so it keeps holding up in everyday use.

03Forged works

Guided intake and follow-up

Multi-step applications that walk people through long forms, capture structured data, and hand it to the teams doing follow-up. Most of the work is state: partial progress, validation, and resuming days later without losing anything.
