About

Nine years, one company, every layer of the stack.

I grew from building WordPress, CodeIgniter and Laravel sites to architecting a SaaS platform that runs on web, Android, iOS, Windows and macOS. Along the way I've owned payments, real‑time systems, cloud migrations and AI features for clients in retail, healthcare, e‑commerce, B2B distribution, media, gaming and education — and learned that the best architecture is the one your team can confidently change.

What I bring
1Architecture for multi‑tenant SaaS with RBAC, subscription billing and offline‑first data — shipped to web, mobile and desktop from shared codebases.
2Payments and wallets — Stripe, PayPal, Razorpay — plus OpenAI, Azure AD SSO, Mapbox and Google Maps integrations.
3Hands‑on team leadership: breaking client requirements into tasks, code review, guiding developers and managing releases.
4An AI‑assisted workflow — Claude Code for implementation and refactoring, Claude Design for UI mockups — with every change checked against measured results.
