The story behind
the systems

Full Stack Developer (~4 years). Built the core of a device-agnostic IoT platform — serving 5–8 enterprise clients and 300–500 devices in production — at a startup that grew from 5 to 8. HTTP + MQTT + WebSocket ingress, a custom DSL called FUS Script with a runtime parser for defining device schemas and field-level transformations (including RSA encryption on selected fields), and a Redis-routed distributed WebSocket layer that keeps connected-device state consistent across clustered instances — load-tested to 10,000 concurrent WebSocket connections.

On top of that core, I’ve delivered OCPP 1.6J integrations for EV chargers, a React Native companion app shipped to Play Store and App Store, a reusable digital twin simulator (initial vertical: dairy industry), an MCP server exposing 150+ tools to LLM agents, and a Sonar-based audio analysis tool (Python signal-processing + Next.js heatmap UI).

Mentored 2 junior engineers and 1 intern as the team scaled from 5 to 8. Now a Full Stack Developer (Contract) at ACS Technologies, building real-time systems and MCP/agent tooling.

Open to opportunities — remote, on-site, or hybrid in Hyderabad. I build systems that scale.

Device-Agnostic IoT Platform

Device-agnostic IoT telemetry core — HTTP + MQTT + WebSocket ingress with a custom DSL (FUS Script) for runtime-parseable device message schemas and field-level transformations including RSA encryption. Redis-routed messaging tracks connected devices across clustered WebSocket instances so horizontal scaling doesn't break cross-instance routing — load-tested to 10,000 concurrent connections. An MCP server exposes 150+ platform tools to LLM agents.

Agentic Company

Config-driven SDLC orchestrator over the Claude Code CLI — define a company of role-agents, hand it a brief, and it runs plan → build → review → QA across phases with human approval gates.

OCPP Charger Simulator

OCPP 1.6J charging-station simulator with a React control plane and insights dashboard — simulates compliant chargers against a live CMS, enabling protocol testing without physical hardware. Supports multiple concurrent simulated chargers over WebSocket.

Digital Twin Simulator

Open-source event-driven TypeScript framework for digital-twin simulators of industrial systems. Register devices and an orchestrator as plugins; the engine ticks them on a scaled clock and streams telemetry over an internal event bus to MQTT and a live dashboard. Ships a full quarry / aggregates-plant as the reference industry.

The evolution

Y1
The Pivot
Software Engineer @ Varsun eTechnologies  ·  2022 – 2023

Joined as an ASP.NET developer; pivoted within months to React + Node.js, leading client-side OCPP 1.6J integration for EV chargers. Designed a multi-site EV management dashboard (backend + frontend) with real-time utilization and power-consumption analytics.

The Architect
Software Engineer @ Varsun eTechnologies  ·  2023 – 2024

Architected FUS Script — a custom DSL with runtime parser — as the extensibility layer of a device-agnostic IoT platform (HTTP + MQTT + WebSocket), enabling runtime-defined device schemas and field-level transformations including RSA encryption. Built a Redis-routed distributed WebSocket layer resolving cross-instance routing under load-balanced scaling — load-tested to 10,000 simulated concurrent WebSocket connections. Shipped the React Native companion app. Delivered a Sonar-based audio analysis tool (Python + Next.js heatmap UI).

The Shipper
Full Stack Developer @ WaveFuel Solutions  ·  2024 – 2026

Converted to WaveFuel FTE. Built an MCP (Model Context Protocol) server exposing 150+ tools — giving LLM agents the platform's full capability surface for device onboarding, control, and analytics — plus an AI chatbot generating on-demand reports over device data. Proposed the microservices split separating device connection from platform controls and built its Redis/BullMQ event layer (circuit breakers, retries, race-condition handling); helped migrate MongoDB → PostgreSQL/Prisma. Built a reusable digital twin simulator (dairy vertical) and a drag-and-drop embeddable form builder. Shipped React/Next.js frontends and the React Native app to Play Store + App Store. Mentored 2 junior engineers and 1 intern; ran code reviews.

Full Stack Developer (Contract) @ ACS Technologies  ·  2026 – Present

Joined ACS Technologies as a Full Stack Developer (Contract). Owning a mobile platform end-to-end — 30+ screens plus the backend services behind them for onboarding and controlling MQTT-based IoT devices, from API design through client integration and release. Advising on architecture (reviewing server design, flagging what won't scale) and building an internal ERP sales module in React.
