Send the product goal, current stack, affected users, deadline, and any crash logs, screenshots, store reviews, or short recordings.
We agree on the outcome, map the riskiest parts, and choose the smallest useful milestone before writing more code.
I will say it plainly, explain the tradeoff, and propose a practical path if scope, architecture, or timeline looks fragile.
Yes. I can pair with your team, review pull requests, lead a feature stream, or help Android, Flutter, React, and backend work connect.

Email [email protected], use LinkedIn, or download the CV linked from the portfolio.
Yes. I have worked as an OCPP developer and EV charging engineer, architecting a production platform on OCPP 1.6 over WebSocket — the protocol state machine, Node.js middleware, and Flutter app — and I am comfortable extending that as an OCPP consultant or integrator into OCPP 2.0.1 work.
Yes. I have shipped both sides: the Python OCPP server and Node.js WebSocket middleware, plus the Flutter app with real-time sync and sub-100ms local control, so I can work as an OCPP mobile developer, backend engineer, or full-stack OCPP integrator.
Open senior Android, staff mobile, mobile architect, technical lead roles with teams that care about systems, shipping, and details users feel.
