What I'm looking for

I’m looking for a team that values Design-First development, Technical Blueprints, and deep blocker analysis—where I can architect scalable fullstack and microservices systems on AWS, deliver reliable CI/CD, and build event-driven features with Kafka.

I’m a Senior Software Engineer with over 7 years of experience in fullstack development, focused on the MEAN/MERN stack, Node.js microservices, and event-driven architectures using Kafka. I lead with a Design-First development lifecycle—deep requirement analysis, blocker identification, and Technical Blueprints—to ensure scalable, high-quality delivery in complex Mono-repo and cloud environments.

In healthcare SaaS, I build features inside a Mono-repo with strict pre-coding documentation for cross-module compatibility, including a Dynamic Game Generation engine driven by real-time patient data and therapeutic goals. In finance, I’ve engineered a high-throughput Node.js microservice that consumes real-time events from Kafka topics, added a persistent data layer for audit-ready retrieval, and automated risk-based Email Notification Services.

I also architect high-availability infrastructure on AWS (AWS Auto Scaling, ELB) to maintain 99.9% uptime, containerize services for reliable deployments with Docker, and execute CI/CD workflows via GitHub Actions for stable production releases. I’ve led and mentored 5+ developers, reduced production bugs by 20%, and optimized MongoDB aggregation pipelines to cut data retrieval latency for large-scale reporting.
