What I'm looking for

I'm looking to solve real-world problems through clean, maintainable code while working in a collaborative environment across frontend and backend technologies.

I'm building full-stack features at PurchAIse.ai across a Java/Play backend and React/Redux frontend. I architected a rules-engine with pluggable constraint types, validation pipelines, and severity modeling.

I implement tree and graph algorithms for recursive inheritance resolution and dot-path traversal. I've integrated OpenAI using structured JSON output, prompt-injection hardening, multi-provider fallbacks, retries, and rate-limit handling.

Previously at PurchAIse.ai, I designed and extended Java REST endpoints, worked with MongoDB queries, aggregations, and schema migrations, and improved DTO, data-model, and error-handling design.

At Pabau Clinic Software, I built React and TypeScript components in Next.js, integrated GraphQL APIs, and wrote Jest and React Testing Library tests for reliable UI components.
