I have completed a series of AI‑focused full‑stack projects between 2025 and 2026, each showcasing specific technical innovations.
Curalink — AI Medical Research Assistant (Apr 2026) – Built a multi‑source RAG pipeline querying PubMed, OpenAlex, and ClinicalTrials.gov in parallel via Promise.allSettled, engineered a 3‑tier LLM fallback chain (HuggingFace 9‑model roster → Ollama local → JS template engine) with intelligent 503 cold‑start retry logic, designed a custom 100‑point ranking algorithm scoring publications on keyword relevance, recency and source credibility – selecting top 8 papers and 6 trials for LLM context injection, and implemented query expansion with disease synonym mapping (18 diseases) and treatment variant lookup.
AI Document Intelligence — RAG Document Q&A System (Mar 2026) – Built a production‑ready RAG application with full pipeline: text extraction → chunking → MiniLM‑L6‑v2 embedding → cosine‑similarity vector store → LLM generation, implemented real‑time token streaming via Server‑Sent Events (SSE) with source citations and per‑user data isolation, and built persistent multi‑document conversation history using a normalized PostgreSQL schema.
ShopAI — E‑Commerce Platform (Feb 2026) – Implemented dual‑token JWT authentication with refresh‑token rotation and reuse detection, integrated Stripe Payment Intents with secure webhook signature verification and idempotency handling, built a BullMQ async job queue handling 500+ jobs per hour for order processing and email notifications, and designed a Redis cache‑aside strategy reducing average API response time from 450 ms to 150 ms.
AI‑Support Desk Agent (Jan 2026) – Full‑stack AI support desk with OAuth user authentication, ticket intake, LLM‑generated structured replies with optional web‑search grounding, cookie‑based authentication, protected APIs, structured LLM outputs, LangGraph agent orchestration, and a React frontend with session‑aware routing.
QuickAI – AI SaaS Platform (Dec 2025 – Nov 2025) – All‑in‑one content‑creation platform offering AI‑generated articles, AI‑driven blog title generator, AI image generation (Anime‑to‑3D styles) with editing, and AI‑powered resume review and feedback.
AI Resume Builder (Nov 2025 – Oct 2025) – React/Node.js/MongoDB resume builder with templates, real‑time preview, customization, and OpenAI‑enhanced professional summaries.
Project Management Platform (Nov 2025 – Oct 2025) – MERN + Prisma ORM full‑stack collaboration tool featuring workspace management, projects, tasks, comments, real‑time collaboration, using Clerk, Vite and Redux Toolkit.
AI‑Powered Blog Application (Aug 2025) – Secure admin login, JWT auth, ImageKit image optimization, AI content generation, and comment moderation.
Social Media Platform (Aug 2025 – Jul 2025) – Responsive social network with connections, feeds, messaging, stories, profiles, discovery, built with React.js and Node.js.
QuickShow – Movie Ticket Booking Platform (Jun 2025 – May 2025) – MERN stack ticketing app with real‑time seat selection, Clerk authentication, Inngest‑driven async tasks, automatic cancellation of unpaid bookings after 10 minutes, and transactional email notifications.
Doctor Appointment Booking System (May 2025 – Apr 2025) – MERN stack system with profile creation, doctor specialty browsing, real‑time slot availability preventing double‑booking, JWT authentication for patients and doctors, and dynamic appointment and fee management.
GreenCart – Online Grocery Store (Apr 2025 – Mar 2025) – Full‑stack e‑commerce grocery platform with Stripe integration, JWT authentication, product listings, cart, order history, and admin dashboard.
JobConnect – Job Portal Web App – Next.js full‑stack job portal with user registration/login, job applications, employer posting, role‑based access, dynamic filtered search, JWT authentication, and resume file upload.
Full Stack Engineer at ModelSuite.ai (Jun 2026 to Aug 2026), Rüsselsheim am Main, Hesse, Germany
Full-stack AI Developer at Independent Projects (Aug 2022 to Jun 2026)
During my stint at ModelSuite.ai I delivered Curalink, an AI medical research assistant built in April 2026 that queried PubMed, OpenAlex and ClinicalTrials.gov in parallel, used a three‑tier LLM fallback chain and a 100‑point ranking algorithm to surface eight papers and six trials; AI Document Intelligence (March 2026), a production RAG system with MiniLM‑L6‑v2 embeddings, SSE token streaming and a PostgreSQL‑backed conversation store; ShopAI (February 2026), an e‑commerce platform that introduced dual‑token JWT with refresh‑rotation, Stripe Payment Intents, a BullMQ queue processing > 500 jobs per hour and a Redis cache that cut response times from 450 ms to 150 ms; and AI‑Support Desk Agent (January 2026) featuring OAuth, LangGraph‑orchestrated LLM replies and session‑aware React routing. Previously, at Independent Projects I created QuickAI, AI Resume Builder, a MERN project‑management tool, an AI‑powered blog, a social network, QuickShow ticketing (auto‑cancelling unpaid bookings after 10 minutes), a doctor‑appointment system, GreenCart grocery store, and the JobConnect portal.
