I’m a Senior Software Engineer with 8+ years of experience, specializing in fintech backend architecture and building high-throughput web applications across the full stack. I focus on designing scalable, event-driven systems (microservices) for complex financial operations like money movements and clearing ledgers.

I’ve developed and productionized backend and API platforms using Node.js and Java Spring Boot, implementing architectural patterns for both frontend and backend systems. I’m particularly strong in cloud infrastructure management across AWS and Azure, including Docker/Kubernetes deployments and CI/CD pipeline setup.

In my most impactful work, I architected a real-time ledger system with a focus on low latency, immutable audit trails, and regulatory-compliant calculations. I also engineered robust queuing and webhook notification mechanisms for reliable, retryable, event-driven status synchronization under peak asynchronous loads.

I began my career building mobile applications and later transitioned into deep backend engineering, where I learned to stay language-agnostic while choosing the right architecture for the business challenge. Today, I’m expanding into AI/LLM-enabled product features—building towards RAG systems and other AI projects while continuing to deliver end-to-end platforms.
