What I'm looking for

I’m open to remote work and interested in evaluation and content-review work where I can apply defined quality standards, make careful judgments on edge cases, and document my reasoning.

At Raenest, I work on a cross-border payments app with 1M+ downloads and 100K+ monthly active users. I lead code reviews, define API contracts and testing practices, and helped bring the ANR rate down to 0.1% and startup speed up by 30%.

At iKhokha, I worked on a Tap-on-Phone contactless payment feature, analyzing failed EMV transactions and fixing edge cases in decline handling. I also classified transaction response codes into clear user-facing messages and added Mixpanel event logging and Firebase feature toggles.

At Mintyn Bank, I rebuilt the banking app interface and delivered the V2 rebuild of the Jaiz Bank app. I also shipped a dollar virtual card feature and set up automated testing and deployment pipelines.

Earlier, at Scienta Consulting, I wrote Java and Kotlin backend APIs and deployed them to Google Cloud, and built C++ modules for water-level monitoring connected to an Android app. I also built Root, an Android app, at Decagon Institute, and have made Pennywise and Currents as personal projects.
