Shankar Kumar

Lead Backend Engineer with 13+ years of experience, currently Python-focused, designing and building scalable, production-grade APIs and backend systems across healthcare and enterprise domains. For 6+ years at SeyfertSoft (client: Abel Healthcare, USA), I have been working in backend engineering on VitalEngine — a healthcare integration platform — covering API design, microservices, async messaging pipelines, cloud architecture, deployment, and production support. I work directly with US stakeholders to take features from design through go-live. My core strength is designing clean, well-versioned REST APIs and event-driven microservices that are reliable, secure, and scalable. Day to day I build Python services with FastAPI and Flask, design RabbitMQ and SQS async messaging pipelines, containerize with Docker, run AWS workloads (S3, SQS, EC2, ECR, EventBridge), and automate infrastructure with Ansible and Packer. What I bring: REST API design — resource modeling, versioning, pagination, error handling, JWT/OAuth auth Python microservices with async, event-driven architecture Production-grade RabbitMQ & SQS messaging with zero message loss AWS cloud operations plus Docker, Ansible, and Packer automation Healthcare data integration in regulated, high-integrity environments Direct US client collaboration in Agile teams, end-to-end ownership Currently open to Senior / Lead Python Backend Engineer roles — remote preferred, or hybrid with flexibility for occasional office visits and team meetups. Having worked fully remote for 6+ years on a live US healthcare platform, I bring proven remote discipline and async collaboration with US stakeholders. Notice period: 1 month, negotiable to 20 days.
