Software Engineer at OneIT

Vandan Sheth

I build dependable backend systems and ship them to the cloud — Java and Spring Boot on AWS and GCP by trade, event-driven and AI-powered tools by curiosity. I care as much about how a thing is made as whether it works.

OneIT

  • Build scalable backend modules in Core Java with RESTful APIs that streamline enterprise workflows.
  • Delivered a CorePlan API integration end-to-end, solo — timed batches sync ~10k records daily and configurations weekly through a multithreaded fetch pool, surfaced in eight Angular 19 chart dashboards.
  • Designed an AI wrapper supporting multiple LLM providers (OpenAI, Anthropic) behind one unified API.
  • Implemented Model Context Protocol (MCP) workflows for contextual memory, tool usage, and knowledge grounding across AI projects.
  • Integrated the Eway payment gateway and Chargebee for secure payments and automated billing.
  • Built Ruby-based automated code-generation pipelines that speed up UI scaffolding.
  • Migrated the entire frontend from Angular 9 to Angular 19, improving performance and maintainability.

An admission

“Intelligence is the only advantage nature gave us — no claws, no wings, no fangs. Just wit. So I use mine as intended: I do the thinking, and the artificial kind does the typing. Some call that delegation. I call it evolution.”

An experiment

graph · breadth-first / depth-first · O(V + E)

Watch an algorithm think

A small interactive product of its own: type-a-problem, see it solved. It steps through a graph traversal like a page from a technical journal — a live diagram beside a monospace state ledger. The animation is driven by the real algorithm, not a model.
