I ship end-to-end at a 5-person startup — device-agnostic IoT telemetry (HTTP + MQTT + WebSocket), a custom DSL runtime, and Redis-routed distributed messaging. Hyderabad, India · open to remote.
Full-Stack Developer (~4 years) shipping production systems end-to-end at a 5-person startup. Built the core of a device-agnostic IoT platform — 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 server instances.
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 toolchain exposing platform actions to LLM agents, and a Sonar-based audio analysis tool (Python signal-processing + Next.js heatmap UI).
Currently mentoring 2 junior engineers and 1 intern as the team scaled from 5 to 8+. Expanding into distributed-systems depth and AI infrastructure patterns on the side — most recently job-manager, a personal Go project exploring deterministic orchestration around sandboxed LLM task pipelines.
Open to remote roles globally (B2B contractor via Deel / Remote / Oyster) and on-site / hybrid in Hyderabad. I build systems that scale.
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.
Client-side OCPP 1.6J integration for EV chargers under a multi-site EV management dashboard. Onboarding across sites, real-time utilization and power-consumption monitoring, analytics surfaced to operators. Built as Varsun's delivery to WaveFuel's core product.
React Native companion app for end-customers of the IoT platform. Device onboarding, usage analytics, user invitations, scene/routine automation, in-app guides. Shipped to both Play Store and App Store.
Reusable digital twin simulation engine. Initial vertical: dairy industry — researched end-to-end device flows, built a flexible multi-device simulator, established a pattern extensible to other industrial verticals. Enables client demos and load-testing of the IoT platform without physical hardware.
Personal exploration project. Deterministic orchestration engine in Go for sandboxed execution of AI task pipelines — queues jobs, isolates runtime in Docker containers, surfaces structured results with automatic error recovery. Pattern-level proof of wrapping non-deterministic LLM calls in deterministic infrastructure.
Sonar-based audio analysis tool for object identification. Python signal-processing pipeline feeding a Next.js UI that renders real-time heatmap visualizations from audio streams.
