Full-Stack Software Engineer

I build scalable, production-ready systems — not just prototypes.

Full-stack developer building REST APIs, microservices, and JWT-secured auth with React, Node.js, and Python — deployed with Docker and Kubernetes. In the last year I've shipped 8+ full-stack products, from a multi-tenant MERN platform for shop owners to a FastAPI + Kubernetes microservice built during my FOSSEE Fellowship at IIT Bombay. I care about code that actually reaches production, not just demos.

About

About Me

I'm a full-stack software engineer who builds real, working products — not just tutorials or clones. Over the past year, I've shipped a multi-tenant MERN platform for shop owners with Gemini-powered quick-add, a zone-based delivery tracking platform with a configurable rate engine, and an AI-powered industrial safety platform used to catch risk before shift changeovers.

I completed two internships at FOSSEE, IIT Bombay — most recently as a Summer Fellow, where I engineered a FastAPI + Kubernetes microservice that replaced a single shared server with isolated, auto-scaling per-user pods, validated with 11 passing unit tests. Before that, I built a PCB Manufacturability Risk Analyzer (Python KiCad plugin) that's now merged into FOSSEE's official open-source repository and used community-wide.

Alongside these, I've also worked on collaborative AI projects spanning computer vision (terrain intelligence for disaster response) and deep learning (plant disease detection for farmers) — comfortable owning a project end to end or working as part of a team.

Currently pursuing my B.Tech in Computer Science at VIT Bhopal University (9.15 CGPA), in my final year.

Currently focused on

Backend systems: REST APIs, microservices, JWT/OAuth2 auth
Docker & Kubernetes deployments in Agile workflows
Open-source contributions used by real developers

May 2026 — Jul 2026 · Remote

Summer Fellowship Intern — FOSSEE, IIT Bombay

Selected for the FOSSEE Summer Fellowship 2026 under the eSim domain at IIT Bombay — a competitive, invite-only program at India's premier engineering institute.
Architected a FastAPI-based Session Manager microservice for eSim Cloud, replacing a single shared Django+NGSPICE setup with isolated, auto-scaling per-user Kubernetes pods.
Implemented full pod lifecycle management with the Kubernetes Python client and Redis (TTL-based idle cleanup), containerized with Docker, and validated with 11 passing unit tests as part of an Agile, sprint-based workflow.
Eliminated cross-user crash risk and resolved 2 critical deployment issues — including a Kubernetes pod-naming conflict and a cross-platform Docker volume mounting failure — on a live Minikube cluster (Certificate).

Semester Long Project Intern — FOSSEE, IIT Bombay

Built the PCB Manufacturability Risk Analyzer, a Python-based KiCad plugin now officially merged into the open-source FOSSEE eSim-KiCad-Plugin repository and used by designers across the community (Official Report · Certificate).
Integrated with the KiCad pcbnew API to automatically detect thermal hotspots, EMI risks, routing congestion, and current-capacity issues — catching design flaws early, before costly hardware iterations.
Authored and submitted a research paper, "PCB Manufacturability Risk Analyzer: A KiCad Plugin for Early Detection of Design Flaws," to an academic conference (under review).

Projects

Saarthi.ai — Shop Ledger & Analytics

Most Indian kirana owners don't keep formal books. Built a multi-tenant MERN platform where a shop owner types or speaks a sale like "sold ₹500 worth of milk" and Gemini structures it into an entry — with a strict golden rule that AI only guesses/narrates, while every total and balance is computed server-side. Includes text/voice/photo quick-add, rule-based alerts, and an append-only udhaar ledger.

LastMile Tracker — Delivery Platform

Delivery platforms need dynamic pricing, scalable agent assignment, and tamper-proof tracking. Built a 3-role (Customer/Agent/Admin) MERN platform with a single rate-calculator function driving both charge preview and order creation, zone + volumetric-weight based rate cards, and an append-only TrackingHistory schema — immutable at the DB level via Mongoose hooks, with email + SMS updates on every status change.

Shift Zero

AI industrial safety platform. India sees 6,500+ fatal industrial accidents annually, most within 2 hours of shift changeover — built an autonomous LLM agent that scores risk in handover notes against live sensor data. Custom RAG pipeline, automated Permit-to-Work checks, multi-tenant auth.

MeetingMind

AI mentor accountability platform. Mentors managing 100+ students were manually tracking commitments in Excel — built a Chrome extension that listens to live Meet captions per-speaker and extracts structured commitments in real time, with maker-checker verification and role-scoped access.

PCB Manufacturability Risk Analyzer

A KiCad plugin, officially merged into the open-source FOSSEE eSim-KiCad-Plugin repository, that analyzes PCB designs for manufacturing risk. Generates trace-density, thermal, and EMI heatmaps, flags hotspots and routing issues, and outputs an auto-generated 0–100 manufacturability score with fix suggestions.

TerrainIQ — AI Terrain Intelligence System

A collaborative group project. An AI-powered terrain segmentation system for law enforcement, emergency response, and disaster rescue — uses a U-Net (ResNet34) model to convert terrain images into mobility intelligence, with risk scoring, vehicle suitability analysis, and drone surveillance modules.

PlantCare AI — Plant Disease Detection

A collaborative group project. A CNN-based deep learning system trained on the PlantVillage dataset that detects plant diseases from leaf images in real time, with Grad-CAM heatmaps, severity assessment, weather correlation, and a multi-language Streamlit dashboard for farmers and agricultural professionals.

eSim Automated Tool Manager

Screening task for the FOSSEE Semester Long Internship — an OS-independent tool manager for eSim that checks dependencies for Ngspice, KiCad, Scilab, and Verilator across Windows, Linux, and macOS, with a clean CLI interface and logging. This submission led to my selection for the internship.
