S. V. Bala Kumaran — 15 years shipping distributed systems, cloud orchestration and APIs. Now vibe-coding at the edge of what backends were never meant to do. Learning daily. Shipping anyway.
I've spent 15+ years deep in backend systems — C# and .NET since 2010, Python, Node and TypeScript along the way. Document-capture platforms processing millions of pages, AI-driven ingestion pipelines, and cloud-native routing engines orchestrated across Azure Functions, Batch and Service Bus.
These days I pair that depth with vibe coding — using AI tooling to prototype fast, explore outside my lane (like this site: GSAP, Three.js, creative front-end), and compress the distance between an idea and a running system.
The constant: learn something every day, then build with it.
RouT.ENgine — automated cable-routing platform. Own the Azure Batch compute pipeline end to end across five environments; Azure Functions orchestration with Managed Identity, Key Vault and a 12-state transaction model bridging cloud to on-prem via Service Bus.
Led a document-ingestion API extracting structured data via OCR and an on-premise ChatGPT model. NestJS + MongoDB backends, prompt engineering with Langchain, deployed on Docker/Kubernetes/AWS.
Cognitive Machine Reading platform digitizing invoices, banking reports and healthcare forms — custom OCR and ML models, dynamic analyst UIs built on Chromium Embedded Framework.
Nine years on FIREFLY, a high-throughput data-capture platform for Accounts Payable, Healthcare and State Tax — multi-tier .NET, multi-threading, and relentless performance optimization.
Know who owes you. In seconds.
WhatsApp-first billing for recurring businesses — gyms, cable and internet resellers, tuition centres. Tracks customers, subscriptions and pending dues, then nudges them on WhatsApp when it's time to pay. No spreadsheets, no memory games. Designed, built and shipped solo.
subskeeper.app →Real people. Real opinions. On camera.
Live-recorded video opinion platform. Anyone can record a short face-cam take on any topic — no account, no file picker, just press record. Thumbs up or down voting, a trending feed powered by Wilson scoring, and spam defences from device fingerprinting to Cloudflare Turnstile.
github.com/madmonk88/vouchcam →Documents in. Structured data out.
On-premise document ingestion workflow for line-of-business customers. Analysts mark labels on sample documents as anchor points; a Windows Service then extracts field values from incoming volumes, routes them through an audit queue, and ships clean JSON.
