Mangu Singh — Software Engineer
I build backend systems that handle real load and real failure modes. At Barclays, I shipped production systems for trade-data validation and risk operations, cutting bulk-read latency by ~40% with JDBC-over-JPA optimisation, and clearing a security backlog across 25+ services in a single sprint. Outside work, I built a Kafka + Redis + Spring Boot backend from scratch: per-user ordering guarantees via Kafka partition keys, cache-aside with Redis (silent fallback, custom Micrometer metrics), raw JDBC for hot-path queries, and 30+ tests covering failure paths. Then built an MCP server on top of it so Claude could manage todos via natural language — Spring AI, SSE transport, stateless protocol layer. I care about the decisions behind the code: why JDBC over JPA here, why this partition key, what breaks at scale. That's the conversation I want in my next role.
