About

Professional summary

I am a senior backend engineer focused on building reliable, data-intensive fintech and financial systems. I specialize in translating complex business and regulatory requirements into production-ready backend services, financial workflows, and integrations.

I have hands-on experience with Python, Go, Java, Kotlin, TypeScript, PostgreSQL, MongoDB, Redis, RabbitMQ, and Docker. My work spans loan management, accounting, reconciliation, regulatory reporting, banking platforms, and event-driven system architecture.

In my current fintech work, I build reconciliation engines, ETL pipelines, reporting systems, and microservices supporting loan lifecycles and profit-calculation workflows. I prioritize data integrity, automation, security, and operational reliability in regulated environments.

I am comfortable owning services end to end, from API and data-model design through deployment, monitoring, and Linux/VPS operations. I have worked with cloud and edge-security tooling, including Cloudflare, SSL termination, and mutual TLS for service-to-service communication.

I am a polyglot engineer with practical experience in Django, FastAPI, Spring Boot, React, Next.js, and SvelteKit. I enjoy working across backend architecture and product delivery, including independent freelance engagements and AI-enabled personal projects.

I bring a security-first, ownership-driven approach to engineering and have a strong record of resolving complex production data issues. I am particularly motivated by backend roles involving financial systems, scalable APIs, data pipelines, and dependable platform infrastructure.
