Suraj Singh R.

I build systems that have to work in production — not demos.

Over 11+ years I've architected and shipped full-stack platforms for BNP Paribas Fortis, ING Belgium, Sciensano, and Extreme Network Solutions, spanning fraud detection, healthcare, pharmaceutical manufacturing, and supply chain. Most recently, I designed a monitoring service that identifies remote-desktop session risk in retail and business banking, cutting account-takeover fraud and saving the bank an estimated €10M annually.

What I actually build:

Backend & architecture: Java, Spring Boot, Node.js/Express, NestJS, REST APIs, microservices, event-driven systems (Kafka, RabbitMQ), across PostgreSQL, MySQL, MongoDB, and MS SQL/Oracle.

Frontend: Next, React, TypeScript, Redux, Angular.

Infrastructure: CI/CD pipelines (Jenkins, GitHub Actions) deploying to Kubernetes on AWS EC2/ECR and Azure Containers — zero-manual-intervention deployment as the standard, not the exception.

Applied blockchain: built a private Ethereum network (go-ethereum) to trace asset provenance in a healthcare manufacturing environment.

Where I'm building next:

I'm actively applying my architecture and full-stack background to agentic AI — prototyping with LangChain, LangGraph, and MCP-based tool-use patterns, and thinking hard about how production-grade distributed systems principles (fault tolerance, observability, deployment discipline) translate to reliable AI agents. This is the intersection I want to keep building in. I'm a hands-on architect who still writes code, reviews it, and owns outcomes end to end — from client discovery through production rollout across banking, healthcare, and enterprise environments in India, Belgium and internationally.
