Prabhat Kumar

I’m a Software Engineer with 2+ years of experience building backend and distributed systems. I focus on scalable microservices, cloud-native architecture, and platform engineering—backed by strong foundations in data structures, algorithms, system design, and distributed computing from IIT Delhi.

At Standard Chartered Ventures (Letsbloom Pvt. Ltd.), I built and secured services end to end. I implemented a Spring Boot venture onboarding microservice with Keycloak IAM, created a compliance-report generator with Apache POI, and delivered fault-tolerant Go microservices leveraging RabbitMQ and Temporal—optimizing database latency to 2s while deploying 7+ microservices on Kubernetes with Terraform and monitoring 30+ active pods.

I’ve also strengthened reliability and performance in customer-facing products. At HealthKo, I engineered a doctor consultation slot-booking system with secure REST APIs, reduced MongoDB latency by 35% using Redis caching and indexing, and prevented double-booking under load with transaction-based slot-locking and expiry cron jobs—plus real-time communication via Socket.io. I integrated Razorpay for payments, automated deployment with GitHub Actions and Docker, and ran services on AWS EC2 behind Nginx.

Most recently, as a Senior Fullstack Engineer, I’ve combined AI workflows with scalable interfaces. I designed database schemas for AI-generated warnings, built GraphQL APIs and Next.js hooks/UI components, and developed Temporal workflows to extract AI-identified tax data into databases with dynamic form UI components. I also created a LangGraph chatbot using Gemini LLM nodes and a chat-history pipeline, turning structured APIs and agent behavior into a cohesive user experience.
