About this gig

I migrate complex financial and commodity data systems with zero data loss and full UAT testing. With institutional experience (JP Morgan, Bin-Talal), I understand compliance, audit trails, and regulatory requirements. Whether you're switching fund accounting platforms, integrating private debt systems, or consolidating trading data, I ensure clean migration, validated accuracy, and minimal downtime. Services include pre-migration audit, data mapping, cleansing, UAT testing, and post-migration support. Most data migrations fail on poor planning I focus on precision, documentation, and peace of mind. Let's move your data safely.

I've spent 6+ years building high-performance systems for top institutions—Goldman Sachs, Bridgewater, EQT. My finance background taught me that precision, security, and uptime are non-negotiable. I bring that institutional rigor to your project. Whether you need a custom web app, scalable SaaS platform, e-commerce site, data migration, or UAT testing—I deliver production-ready solutions that scale. I code with a banker's discipline and a builder's agility. Fewer bugs. Faster performance. Real-world reliability. You dream it. I build it. First-class quality, every time.
