I build software businesses can't afford to get wrong.

Senior Software Engineer with 7+ years designing, building and maintaining enterprise systems: billing and fintech workflows, CRM and HR platforms, ERP integrations, and the data migrations that move them forward.

01Selected work

Systems where the details decide the outcome.

Client and system details stay confidential. These pages describe the problems and how I approach them; I am happy to go deeper in conversation.

02How I work

Reliable software is mostly a set of habits.

  1. 01

    Correct before clever

    In billing and finance, a wrong number costs more than a slow one. I design data models and transactions around integrity first, then optimize.

  2. 02

    Change without stopping the business

    Migrations and modernization ship in steps, with backward compatibility, so the people who depend on a system keep working while it changes underneath them.

  3. 03

    Readable for the next engineer

    Clear boundaries, plain names and predictable structure, so the system can be changed safely by someone who was not in the room when it was built.

  4. 04

    Fundamentals over frameworks

    Languages and frameworks change. Data modeling, consistency, clean interfaces and careful operations do not, and they are what I bring to any stack.

03Expertise

Grouped by the problems they solve. The tools are the ones I use today; the principles carry across stacks.
