Cover image for MessyAPI is a production-ready developer

MessyAPI is a production-ready developer infrastructure platform I built to eliminate repetitive data utility work. It gives developers one API to clean, validate, match, transform, protect, and analyze messy data instead of rebuilding those capabilities for every application. I designed the platform around real production requirements, including API-key authentication, tenant isolation, usage metering, rate limiting, idempotency, asynchronous jobs, retries, webhooks, observability, and secure data handling. MessyAPI also includes JavaScript and Python SDKs, OpenAPI, MCP support, CLI tooling, RapidAPI integration, interactive testing, and composable workflows for chaining multiple data operations together. The goal was simple: turn common data infrastructure developers repeatedly build themselves into one reliable API.

Cover image for I designed and built MessyProof

I designed and built MessyProof to solve a growing problem with AI-built software: generating an application is getting easier, but understanding what was actually built — and whether it’s production-ready — is still difficult. MessyProof acts as an independent verification layer, analyzing an application’s architecture, dependencies, integrations, changes, security signals, and production readiness. It turns that analysis into a plain-English App Passport backed by evidence rather than assumptions. I led the product strategy, UX, verification model, application architecture, integrations, and go-to-market positioning from concept through implementation.
