Currently MagLoft's sole engineer.

Day-to-day work spans 8+ products, 30+ GCP services, and 50M+ API requests/month for 400K+ readers. This year I shipped 4 enterprise client projects, all on time with no production incidents, and brought infrastructure cost down 10.5% by tightening Cloud Run and upgrading Cloud SQL.

Before going solo I led a small team of three. We shipped 10+ enterprise projects, 50+ features, and 6 major Amway products live across EU, South Africa, and ANZ, along with AI-powered Text-to-Speech and SEO automation.

Worked on MagLoft's mobile platform for 9+ years, powering apps like Amway Xperience: 400+ iOS and Android updates with consistent 4.5★ ratings and 99.5%+ crash-free rates.

14 years across mobile, full-stack, and infra. Solo work has taught me to scope ambiguous problems on my own and own what breaks. Stayed at MagLoft 9+ years because they kept opening up bigger surfaces: Mobile Full-Stack Lead Solo. Ready for the next one: bigger team, deeper product, or both.

Best fit: product or platform team where ownership and end-to-end thinking matter more than process. Most useful in publishing, mobile, or GCP-heavy products. Title is flexible; what matters is the surface, the team, and the comp.
