I design and deliver REST and gRPC APIs, event-driven architectures, and distributed services. I have worked with payment gateways, crypto services, blockchain APIs, and trading platforms to support reliable financial workflows.

I am experienced with PostgreSQL, Redis, Kafka, RabbitMQ, Docker, Kubernetes, and cloud environments. I focus on system reliability, observability, performance optimization, encryption, and CI/CD automation.

I have built solutions for crypto payments, stock trading, portfolio analytics, booking platforms, digital wallets, and financial inclusion products. My work includes API integrations, smart contract interactions, reconciliation automation, and real-time transaction updates.

I collaborate effectively with product, compliance, and engineering teams to deliver highly available fintech platforms. I apply clean architecture, microservices principles, and agile development practices to build maintainable systems.
