What I'm looking for

I’m looking to lead and build secure, high-throughput backend systems in payments, fraud, and distributed architectures—prioritizing reliability, performance, and strong engineering standards, while guiding teams through complex challenges.

I’m a Senior Backend Engineer and Engineering Lead with 5+ years of experience designing and building secure, scalable, and fault-tolerant distributed systems across fintech, payments, and digital platforms.

I’ve led high-throughput backend services and payment infrastructure with a strong focus on reliability, performance, and security—building fraud prevention systems and engineering teams to deliver consistently under pressure.

In my most recent role, I scaled engineering team operations using CI/CD automation and stronger security practices, architected a machine-learning fraud detection system (~80% accuracy), and supported $2M+ transaction volume through fault-tolerant microservices and message-queue-driven asynchronous communication.

I also build with modern security and resilience in mind, from OWASP hardening and Redis-based race-condition prevention to secure key management (Shamir’s Secret Sharing), secure enclaves for payment services, and production observability with real-time logging and alerting.
