Bring me the tricky parts.
I design and build web and mobile products, APIs, and SDKs. I can get up to speed with any technology your team uses. I have experience in fintech, blockchain, developer tools, and AI, and I'm open to roles in any field.
Things I like untangling
- Features where the interface, API, and background worker need to agree.
- Payment SDKs with encrypted requests, typed errors, and clear retry signals.
- Distributed systems with queues, idempotency keys, and partial failures.
Selected work
- SpendinAt Spendin, I work with the team on payment and purchase services, improving how the backend handles retries, late callbacks, and failures in external systems.
- Blue OrchidAt Blue Orchid, I work on an AI platform built with TypeScript, Cloudflare Workers, D1, and R2. My security work covers MCP OAuth, rich-text input, agent approvals, and request limits.
- KPPAYI brought the user, merchant, and admin apps into one monorepo and built the developer portal and SDKs that make the payment gateway easier to use.
