The positioning

I build technology — and products — that help people and businesses work smarter. A mix of tech, business & human.

01 / VALUES

Good human values — helping society, children, animals, and protecting the environment.

02 / CRAFT

Great products start with understanding people, attention to detail, and craftsmanship.

03 / APPLIED

Always drawn to the applied side — experiments, real use cases, learning by building.

What I do

Three roles,
one operator.

01

Build & lead production SaaS

Lead engineering for MarketBuzz — CRM, SMS marketing & analytics on the Clover App Market. Architecture through delivery, optimization, stakeholder comms, and team mentoring.

Lead, mentor & bridge

Turn product goals into scalable architecture. Mentor engineers, work closely with stakeholders, and step into ambiguous product problems to align teams around shared outcomes.

Two ventures, one philosophy.

Building software and physical creative work taught the same lesson — great products start with understanding people, detail and craft.
