What I'm looking for

I’m actively seeking remote or contract engineering roles with deep technical ownership and entrepreneurial drive—building fintech/SaaS products end-to-end. I’m available to overlap with any timezone and can start immediately.

I’m a results-driven Full-Stack Software Engineer and SaaS Founder with 5+ years delivering production-grade applications in fintech and SaaS—often architecting multi-tenant platforms end-to-end. I build secure payment pipelines and integrate complex payment APIs, leading full product lifecycles independently.

Recently, I engineered a multi-tenant SaaS POS platform with four role-based dashboards and granular RBAC, plus an offline-first Socket.io data architecture that auto-syncs to prevent zero data loss for field agents. I also developed a companion React Native app with QR/barcode scanning and end-to-end payments, and built a webhook processing pipeline with JWT auth, RBAC, and multi-factor authentication for real-time transaction verification.
