1.5 years in production fintech. I was the sole author of the identity and authentication service behind an advisor-facing wealth platform, and one of the engineers who moved that platform onto hexagonal architecture across 10 microservices. My last company ceased operations in June 2026 and released the whole team, so I'm available now — and I've spent the gap writing Java in public, including a merged fix to ClickHouse's official JDBC driver.

ClickHouse · clickhouse-java · merged
Three DatabaseMetaData methods built their WHERE clause by concatenating the caller's pattern straight into SQL. A single quote closed the literal early — which broke legal ClickHouse identifiers and opened a quote-injection hole. Replaced with bound parameters. +106/−9, merged by the maintainers into a 1.6k-star driver.
Adyen · adyen-java-api-library
Added the absent afterpaytouch_US and DEFFERED_DEBIT enum values to Adyen's production Java payments SDK, so both resolve instead of failing deserialization.
TROLIE · spec · merged + six more
Standardised rate-limit headers to X-RateLimit-* across the TROLIE OpenAPI spec and docs (merged). Open pull requests to Autodesk Forge, InterFax, Infor's ION SDK, Mirantis cri-dockerd and Turso.

Investlytics — Software Engineer
25+ REST APIs across a 10-microservice platform in Java 21 and Spring Boot. Sole author of the Identity & Authentication service — JWT, RBAC, request validation — handling all production auth.

personal projects — not client work, and labelled that way on purpose
Personal Growth OS · alpha
Spring Boot modular monolith talking to a FastAPI RAG engine through a Resilience4j gateway — circuit breaker, retry, timeout. Built it to track my own habits; kept building because it worked.
Echoe · deployed
Spring Boot on Java 21 with anonymous JWT auth — refresh-token rotation and theft detection — an LLM conversation engine and an STT/TTS voice pipeline. Dockerised and deployed on Render.
