Hi, my name is
Sumit Verma.
I engineer systems that scale.
I'm a backend engineer who builds robust, high-throughput distributed systems. Currently at Bajaj Finserv Health, I design and ship enterprise-grade healthcare integrations, event-driven architectures, and secure infrastructure from scratch.
See what I've builtAbout Me
I'm a software engineer based in Ayodhya, who thrives on building backend systems that are fast, resilient, and elegantly designed. My journey started with competitive programming at VIT Bhopal — cracking problems on LeetCode, CodeChef, and HackerRank — which taught me to think in algorithms and optimize relentlessly.
Today, I apply that mindset to real-world engineering. From architecting FHIR-compliant healthcare integrations for international governments to designing event-driven pipelines that deliver notifications in near real-time, I focus on building things that genuinely matter and work at production scale.
Here are a few technologies I work with daily:
- Java & Spring Boot
- Apache Kafka
- Redis
- AWS (EC2, S3, RDS, Lambda)
- Docker & NGINX
- Elasticsearch
- PostgreSQL & MySQL
- Prometheus & Grafana
Where I've Worked
Backend Engineer
@ Bajaj Finserv Health- Built a FHIR/HL7-based enterprise integration with Qatar's Ministry of Public Health end-to-end — from development and connectivity setup to production deployment — enabling interoperable eligibility verification and enrollment workflows across borders.
- Designed and deployed an NGINX-based HTTPS gateway that centralized all service traffic through a single secure entry point, reducing the attack surface and eliminating insecure public exposure.
- Implemented IP- and token-based rate limiting to mitigate abusive traffic (~30% reduction), securing high-cost APIs against unauthorized usage.
- Migrated a scheduler-based notification system (email/SMS with up to 20s delay) to a Kafka event-driven architecture, slashing delivery latency by 90%+ and enabling near real-time message dispatch.
- Engineered a reusable MFA and PIN-based authentication module with Redis caching, cutting response latency by 40–50% and significantly reducing database load.
Backend Developer
@ Stealth Startup (UK-based)- Led the end-to-end architecture and delivery of a UK-based property platform's backend from 0→1, including automated property draft and admin approval workflows.
- Architected an asynchronous communication microservice handling high-volume Email, SMS, WhatsApp, and OTPs, decoupling core logic and significantly reducing API response latency.
- Engineered a highly scalable property discovery engine using Elasticsearch for complex geolocation filtering, and implemented strategic caching to mask slow third-party API latency.
- Fortified system reliability by deploying reverse-proxy rate limiting for DDoS mitigation and migrating media storage to AWS S3 using secure, direct client-side uploads to reduce server payload.
- Containerized the backend architecture with Docker and established a comprehensive observability stack (Prometheus & Grafana), alongside robust database disaster recovery protocols.

Featured Projects
InfraPilot
Architected modular Infrastructure-as-Code (IaC) to provision highly available AWS VPCs, ALBs, and ECS Fargate clusters via Terraform. Secured deployments using keyless OIDC authentication with GitHub Actions and DynamoDB state locking. Engineered zero-downtime CI/CD pipelines enabling dynamic resource scaling via YAML manifests.
Fin-Ping
AI-powered backend for personal finance apps to track bank downtime and reduce failed data fetches. Uses AI to parse downtime notification emails, extract inconsistent bank names, and normalize them into a reliable status feed. Deployed on AWS with automated health checks.
Agri Weather
Real-time agricultural weather monitoring backend that aggregates external weather APIs to provide crop-specific forecasting and alerts. Features persistent weather history tracking for pattern analysis and yield prediction insights.
