I've built production-grade Java and Spring Boot systems at Amigoscode, Rodela Techhouse, NHX, and SpaceYaTech. My work spans AI-powered interview tooling, stablecoin issuance infrastructure, CI/CD pipelines, secure authentication, and REST APIs serving 500+ active users.

At NHX, I design secure event-driven microservices for a Hedera-based stablecoin platform using Java, Spring Boot, PostgreSQL, and Azure. I implemented RBAC, JWT security, paginated APIs, and Flyway migrations to separate issuing companies from platform administrators.

I also co-founded the Kenya Java User Group, growing it to 500+ developers through workshops, mentorship, and Kenya's first Java conference. I enjoy sharing practical system design, architecture, and event-driven engineering knowledge with the community.

Designed the backend for a Hedera-based stablecoin issuance platform, building secure, event-driven microservices in Java, Spring Boot, PostgreSQL, and Azure. Implemented RBAC with Spring Security and JWT, enforcing strict separation between issuing companies and platform administrators, with paginated REST APIs and Flyway migrations.

Nov 2025 - Feb 2026 (3 months)

Designed GitHub Actions CI/CD pipelines for three production Spring Boot microservices, automating build, test, and deployment to DigitalOcean. Hardened authentication by migrating client-side JWTs to HTTP-only cookies with Spring Security, and cut latency on transactional flows with an asynchronous Spring @Async email executor.

Built RESTful APIs for the Mentorlst mentor-mentee platform (Spring Boot, PostgreSQL), serving 500+ active users. Tuned Spring Data JPA fetch strategies to eliminate N+1 queries on high-traffic endpoints, cutting average API response time by 20%.
