What I'm looking for

I’m open to discussing relocation and EU work permit sponsorship.

At Volet, I own release quality for a 2.4M-user FinTech wallet and lead its migration from legacy ADV1 to the new Rocken platform across 12 stages. I manage API-to-database reconciliation, stage-level reporting, quality gates, and production readiness for monthly releases and hotfixes.

I set up Claude Code and Cursor with 11 MCP servers and designed 19 custom skills for repeatable QA workflows. I use this system to verify requirements across backend, web, admin, Android, and legacy products, with machine-checked gates and audit-ready reports.

Earlier, I led QA across distributed healthcare and finance teams at NIX, validating ETL pipelines and data migrations, and managed delivery across parallel programs. I’ve also built and scaled QA teams, with a peak team size of 12.
