Three production platforms shipped solo, from architecture to deployment.
Engineered Solo. Delivered to Production.

Pre-AI-era fundamentals, force-multiplied by modern AI workflows. I build complete production products solo — designing the data layer, engineering backend services, crafting responsive UIs, and deploying cloud infrastructure without needing team handoffs or pre-existing playbooks.
Engineered Marg (hospital indoor navigation PWA with voice AI), CrewPilot (field ops platform), and Med Assist (AI medicine OCR assistant). I leverage tools like Claude Code, Cursor, and Copilot daily on top of 7+ years of core software engineering discipline.
Featured Case Studies
Production platforms engineered end-to-end. Problem solved, scope shipped solo, stack supporting.
GPS breaks down inside hospitals and large public institutions in India — zero indoor navigation, leaving patients and visitors stranded with no way to find specific departments, counter desks, or floors.
Engineered full production platform solo in ~4 months (started 04/2026, ongoing): built Next.js/React/TypeScript frontend, evaluated three real-time voice APIs before shipping MargAI assistant, 7-locale i18n, offline PWA capabilities, dual-database architecture (Supabase + Pinecone) for community mapping and AI retrieval, gamified contribution engine with redemption system, and multi-role auth.




Field operation teams struggle with real-time coordination across tasks, asset tracking, incident reporting, and voice-assisted dispatching.
Engineered field operations platform with task assignment, asset tracking, approval workflows, real-time messaging, and an AI assistant featuring Gemini Live voice integration.



Patients struggle to decipher prescription medicine strips, understand side effects, or track their scan history accurately.
Engineered OCR-to-LLM medical analysis pipeline that parses medicine strip photos, extracts active ingredients, retrieves dosage guidelines, and maintains encrypted scan history.



Past Projects & Prototypes
Additional platforms engineered solo across mobile, AI systems, and real-time infrastructure.
Adshot AI
Prototype (GPU Deferred)Agentic media generation system producing 10–30s social video ads under 5 minutes using multi-step LLM workflows. Deployment deferred due to cloud GPU allocation requirements.
Dateme
Solo Venture (Concluded)Cross-platform real-time dating application built solo from scratch. Includes preference-based matching engine, real-time Socket.io messaging, and custom mobile state layer.
Engineering Timeline
Outcome-proven roles across full-stack engineering, performance optimization, and AI automation.
Lead Engineer — Marg (gomarg.in)
- Architected and engineered complete indoor navigation platform solo from zero to production deployment.
- Evaluated three real-time voice assistant architectures before selecting and integrating Gemini 2.5 Flash for MargAI.
- Implemented 7-locale i18n support, offline-first PWA caching, and dual-database indexing (Supabase relational + Pinecone vector RAG).
Full Stack & AI Engineer
- Delivered production web and mobile software solo for clients, owning architecture, database schema, frontend UI, and deployment.
- Designed agentic multi-step workflows with LangChain & LangGraph, embedding LLM automation directly into existing business processes.
- Consulted early-stage products on performance optimization, API architecture, and rapid solo-velocity execution.
MERN Stack Developer
- Reduced page load times by 15% across core product routes by refactoring legacy Next.js rendering paths and state flow.
- Reduced HR candidate screening time by 30% through automated AI interview bot integrations.
- Established engineering SOPs, code review guidelines, and standardized TypeScript interfaces across the codebase.
Frontend Developer
- Achieved 20% reduction in load times and 15% uplift in user engagement across high-traffic D2C storefronts (mCaffeine, Borosil).
- Engineered custom Shopify Liquid templates and Node.js middleware for seamless third-party app & analytics integrations.
- Streamlined deployment workflows to cut client feature go-live timelines substantially.
Solo Engineer — Dateme App
- Engineered cross-platform mobile dating application solo from prototype to store readiness in 3 months.
- Built low-latency matching service using Node.js and Socket.io, paired with a React Native offline-tolerant state model.
Software Application Developer
- Promoted from Backend to Full-Stack Developer within initial engagement period after delivering high-throughput MongoDB aggregation pipelines.
- Built RESTful microservices in Node.js/Express and integrated them with responsive React/Next.js client portals.
Software Engineer — Frontend
- Engineered core cross-platform mobile UX features in React Native for social food-discovery app.
- Optimized mobile app data persistence layer (Realm) and introduced clean state management patterns.
