Tech lead. Payments, crypto, and the plumbing between.
I build the backend systems money moves through — payment rails, crypto infrastructure, KYC that holds up, and the SDKs merchants integrate against. Currently leading engineering at Vittas Inc.

UbyFlow
Ubyco · 2026
The Future of Money, Built for You. I own the backend architecture: multi-chain deposit infrastructure across 8 assets and 7 networks with per-user address provisioning and HMAC-verified webhooks, tiered KYC against a liveness selfie, RSA-encrypted passcodes, and an in-house RFC 6238 TOTP engine for two-factor.

Finqard
Ubyco · 2026
Trade gift cards for cash or crypto, spend with virtual Visa and Mastercard, and pay bills from one balance. I own the identity domain the whole platform builds on, plus the API contract — a strict meta/data envelope enforced by a global interceptor, with Swagger schemas generated from the same builders so the docs can't drift.

Edatech
Edatech.ai · 2026
Transforming education through intelligent data analytics and personalised learning. I lead the full-stack rebuild: a 22-game learning module, an objective-centric lesson planner, an exam-paper engine with board and topic scoping, a four-tab QA portal, and a CloudFront media pipeline that moved 271 assets out of the repo.

Vittas International
Vittas Inc (Techstars '22) · 2023
Tailored lending for healthcare providers. I built the React Native loan application end to end, then took over technical direction across mobile, backend and frontend — including the merchant integration surface, its security model, and the Terraform infrastructure that delivers it.

TiqBuy
TiqBuy · 2024
Multi-category retail with secure checkout, wishlists, order tracking and nationwide delivery. I led the MedusaJS v1.20 to v2.16 platform rewrite — re-architecting modules, data models and the event system onto v2 — and patched a live RBAC gap that granted read permissions to every admin regardless of role.
