Where I've worked

Praalak Tech Solutions

Jul 2025 — Present

Software Engineer · Vadodara, Gujarat · Hybrid

Core Engineering

  • Architected reusable backend services, authentication/authorization, and CI/CD pipelines — including shared multi-tenant PostgreSQL patterns (Node.js/Deno, Supabase RLS) — powering distributed systems across production platforms.

Coach Sophia — AI platform

  • Engineered the multi-tenant backend (Node.js, PostgreSQL, Supabase) for a production AI platform, implementing authentication, authorization, and Row-Level Security across serverless Edge Functions to isolate tenant data.
  • Implemented production RAG pipelines (LangChain, LangGraph, vector embeddings) powering an AI chat experience with context-aware conversations.
  • Delivered the React and React Native clients — chat interface, document uploads, real-time workflows — deployed to production across web and mobile.

Regenerative Organic Alliance — traceability & compliance

  • Designed a Go backend compliance engine enforcing certificate business rules, validating shipment dates against scope-certificate windows across multi-certificate, multi-site cases.
  • Extended GraphQL/Hasura queries to support the validation engine and built a React/Ant Design frontend surfacing real-time errors; added test coverage (Go, Vitest) and shipped to production.

TTPro — enterprise traceability platform

  • Strengthened an existing enterprise traceability platform: implemented new certificate-validation features, fixed production bugs, and extended backend validation logic, building on the ROA architecture.

Physical Research Laboratory

Jan 2026 — Jun 2026

Software Engineer Intern · Ahmedabad, Gujarat · On-site

  • Engineered a Python data pipeline and PyQt6/Matplotlib desktop analysis platform for astronomical polarization camera telemetry, delivering visualization comparable to SAOImage DS9.
  • Optimized a vectorized NumPy calibration engine computing full Stokes parameter maps; resolved rendering bottlenecks via parallel QThread computation, cutting frame-update latency to near real-time.

Client work

ClimaGrowth — AgTech advisory platform

climagrowth.in

Freelance Software Engineer

  • Backend architecture: independently architected a Go/Fiber API gateway with Redis caching and PostgreSQL/Supabase, integrating Open-Meteo, NASA FIRMS, and Agmarknet data sources.
  • Mobile application: built an offline-first, multilingual (Gujarati/Hindi) React Native app for field-level crop advisory access.
  • AI infrastructure & deployment: implemented a Gemini-powered RAG voice assistant (ClimaVOICE) and deployed the full stack — marketing site, backend, and mobile — to production.
