What I bring
Product vision and strategic thinking, informed by experience across multiple domains and at their intersections
End-to-end ownership: I keep the full project context in view, set priorities, and revise them as new signals emerge
Broad technical range: I stay current with emerging technology, work across stacks, and create new technologies or standards when a project calls for them
A practical understanding of how engineering culture affects delivery efficiency and product quality
The ability to establish effective AI-assisted development processes and keep project context coherent for both people and AI tools
Clear, constructive communication and an ability to work well with people
A focus on solving the underlying problem, not merely automating the existing process
Comfort with uncertainty and a knack for finding unconventional solutions
A strong design sensibility grounded in my background in UX/UI design

Dressformer

Period	Role
2015 - 2016	Tech lead

The goal was to enable online virtual fitting: showing garments on a mannequin configured to match a user's body measurements.

We had a physically based cloth simulation, but it was too resource-intensive to scale as a web service. I proposed an alternative approach: pre-rendering garment shapes and quickly interpolating between 3D mesh vertex positions to approximate the simulation result. This made real-time online fitting practical while preserving visual quality close to the original simulation.
