Where I've worked

Thirteen years of Android across media, platform, banking, and payment terminals.

AI media & language

I've shipped Android for thirteen years — media apps at Agora, platform work at Huawei, mobile banking at Capco, and now a bank and payment terminals at Chabre. The work I care about starts after launch: keeping long-lived code easy to change, and the risky paths tested.

What I bring

• Legacy, made shippable. Long-lived modules, clear seams, and a build the team can still run.
• Correctness where it costs. Lifecycle, offline state, and tests around the logic that touches money.
• AI in the loop. Agents, MCP, skills and hooks in the daily workflow — not a demo.

Beyond code

This site is a working Android launcher — notification shade, recents, and real app screens. No emulator.
