2022 – Present
Mangobaz IT Solutions
Lead Developer

Senior Software Developer & Systems Architect

  • Architected and delivered mission-critical web applications, high-throughput REST APIs, and microservices for enterprise and global clients.
  • Engineered transactional outbox patterns over Apache Kafka and RabbitMQ, guaranteeing strictly-once delivery semantics for high-concurrency event buses.
  • Eliminated database bottlenecks across Microsoft SQL Server: tuned B-Tree indexes, mitigated lock contention, and reduced P99 latency below 10ms.
  • Constructed zero-allocation C# memory pipelines utilizing ArrayPool<T> and Span<T>, shaving 65% off memory GC pressure.
  • Authored automated chaos-testing runbooks and CI/CD pipelines deploying to Docker and Windows Server (IIS).
⚡ Scaled distributed architectures to 45,000 operations/sec with 99.9% production reliability.
