What I'm looking for

I’m looking to build and scale cloud-native backend systems—focused on distributed reliability, event-driven workflows, and strong observability—where I can own architecture decisions, improve performance, and deliver secure, maintainable APIs.

I’m a Senior Back End Engineer with 7+ years of experience building scalable APIs, distributed systems, cloud-native platforms, and event-driven backend services across fintech, healthtech, travel, media, education, and SaaS products. I focus on backend reliability, scalability, maintainability, observability, and secure enterprise application design.

I’ve led backend service-layer development for multi-tenant workflows with RBAC and approval lifecycles, built REST and GraphQL APIs, and implemented idempotent event handling with retries, webhook validation, and asynchronous background processing. I use queue-based architectures (BullMQ, RabbitMQ, Kafka-style workflows) and production-grade CI/CD and observability to keep systems dependable under real load.

I also architect modular backend systems using Clean Architecture, CQRS-style patterns, and DDD concepts—optimizing PostgreSQL-backed workloads through caching, indexing, and query improvements. From health interoperability (FHIR-aligned workflows) to short-form media streaming (HLS with ffmpeg) and AI-assisted document workflows (LLM APIs, RAG pipelines), I build backend foundations that teams can scale confidently.
