With 15+ years of enterprise delivery, I build full-stack SaaS platforms and web applications that are production-ready, well-architected, and built to last. If you need someone who can own the full solution — backend, frontend, cloud, and AI integration -- without handoffs or gaps, that's exactly what I deliver. **What I Build** → SaaS platforms — multi-tenant, scalable, subscription-ready → Enterprise web applications — end to end, Java + TypeScript stack → AI-powered features — RAG pipelines, LLM integrations, workflow automation → REST & GraphQL APIs — clean design, documented, production-grade → ITSM solutions — service management platforms, workflow engines, ticketing systems → Fintech applications — reconciliation engines, payment integrations, transaction systems → Healthcare platforms — HIPAA-aware architecture, secure data handling → Cloud infrastructure — AWS-native deployments, Docker, Kubernetes, CI/CD **How I Work** I don't just write code — I think about your system holistically. Every project gets clean architecture, proper documentation, and delivery you can build on. I communicate proactively, flag risks early, and don't disappear mid-project. Fast turnaround without cutting corners. Senior-level thinking at every stage. **Technology Stack** → Backend: Java, Spring Boot, Spring Security, Node.js, NestJS, REST APIs, GraphQL, Microservices → Frontend: React.js, Next.js, TypeScript, Tailwind CSS → AI & GenAI: OpenAI API, RAG Applications, LLM Integration, AI Workflow Automation, Claude API → Cloud & DevOps: AWS, Azure, GCP, Docker, Kubernetes, CI/CD, GitHub Actions, Terraform → Databases: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch → ITSM: ServiceNow integrations, workflow automation, ticketing system architecture **Selected Delivery** → Built a financial reconciliation engine for BNY Mellon — processed 2M+ transactions/day, reduced reconciliation time by 60% → Architected a SaaS bookkeeping platform that scaled to 10,000+ users — acquired by Paymentus → Delivered microservices backend for a cybersecurity SaaS platform serving 500+ enterprise clients → Built and deployed ITSM workflow automation reducing ticket resolution time by 40% across 3 service desks **Best Fit Projects** → SaaS MVP or platform build — greenfield or existing codebase → AI feature integration into your existing product → Backend API design and development → ITSM platform build or ServiceNow integration → Legacy system modernisation → Fintech or healthcare application development **Not a fit for:** Pure frontend pixel-pushing, WordPress/Shopify customisation, or one-day quick fixes with no scope. I keep my project load intentionally small — so every client gets full attention, fast communication, and senior-level delivery. **Let's talk about what you're building.**

🌟 𝐆𝐫𝐚𝐛 𝐚 𝐅𝐫𝐞𝐞 𝟒𝟎-𝐌𝐢𝐧𝐮𝐭𝐞 𝐂𝐨𝐧𝐬𝐮𝐥𝐭𝐚𝐭𝐢𝐨𝐧 – let's map out the plan. Need a React Developer who ships full-stack products on time? I build SaaS platforms, marketplaces, and web apps with React, Django, and Next.js - 9+ years, 30+ projects delivered, Top Rated Plus on Upwork. I combine senior React front-end work with deep Django/Python back-end architecture - so you get one engineer who owns the full product, not a hand-off chain. I've led dev teams of up to 4 engineers and served as software architect on 2 engagements, which means I scope projects to avoid mid-build surprises. Most of my clients come back for the next project because I communicate clearly, respond fast, and deliver without drama. 𝐓𝐫𝐚𝐜𝐤 𝐫𝐞𝐜𝐨𝐫𝐝 5 years on Upwork, 22 clients served, 1,000+ hours delivered, 100% Job Success Score, Top Rated. I've shipped 30+ Django REST Framework APIs and 20+ full-stack web applications from scratch, with [4/5] years leading dev teams and 2 as a software architect – which means I know how to scope a project so it doesn't blow up halfway through. 𝐂𝐨𝐫𝐞 𝐓𝐞𝐜𝐡𝐧𝐨𝐥𝐨𝐠𝐢𝐞𝐬 -Backend: Python, Django, Django REST Framework, FastAPI, Flask, Node.js, Express.js, NestJS -Frontend: React.js, Next.js, TypeScript, JavaScript, Redux, Tailwind CSS, Material UI -Mobile: React Native (cross-platform Android/iOS) -AI Integration: OpenAI API, ChatGPT integration, AI-assisted features, recommendation systems -Database & Cloud: PostgreSQL, MySQL, MongoDB, Redis, Elasticsearch, AWS, Azure, Digital Ocean, Firebase, Supabase -DevOps: Docker, Kubernetes, Nginx, GitHub Actions, CI/CD pipelines -Payments: Stripe integration, Authorize.net, subscription billing, invoicing -Real-Time Systems: WebSocket, Django Channels, Daphne, live chat, real-time notifications -Testing: Unit testing, integration testing, Pytest Additional: API integrations, third-party API development, SaaS development, MVP development, legacy code refactoring, code review, technical consulting.

𝐒𝐩𝐞𝐞𝐝 𝐭𝐨 𝐦𝐚𝐫𝐤𝐞𝐭 I prioritize fast delivery so you can start testing and generating revenue sooner. Custom architecture built on proven frameworks (Django, React, Next.js) means you're not paying to reinvent infrastructure - or to maintain something overengineered six months from now. 𝐂𝐨𝐦𝐦𝐮𝐧𝐢𝐜𝐚𝐭𝐢𝐨𝐧 Straightforward updates, fast responses, no unnecessary meetings. I work async-friendly, so progress doesn't stall just because we're not online at the same time. 📩 Got a project in mind? Message me and I'll get back to you within a few hours.

Most AI agent projects stall in demo mode. I ship them into production. I spent six years building production mobile and backend systems before specializing in AI agents, LLM integration, and voice AI. Every system ships with logging and observability through LangSmith and Arize, plus documentation your team can run without me. I build for SaaS founders, and for healthcare, fintech, real estate, and hospitality teams, each with its own compliance and integration constraints. Where I focus: Multi-agent systems, orchestrated with LangChain and LangGraph, using staged execution so agents can't take irreversible actions unsupervised Voice AI through Retell AI and ElevenLabs, wired into your existing phone line or WhatsApp number RAG and document intelligence, built on Pinecone or Qdrant, on top of whatever OCR or ERP data you already have LLM integration across OpenAI, Claude, and Gemini, picked per task rather than locked to one vendor My Recent production work: 1: An AI investment advisor generating real-time market scores and multilingual analysis for institutional investors 2: A multimodal healthcare platform combining voice, chat, and OCR for round-the-clock patient support 3: A lead-scoring agent ranking properties across a 140M+ listing database for a real estate platform 4: A voice and WhatsApp booking agent for a multi-location restaurant group, saving an estimated £50K a year in front-desk hours 5: An OCR and drafting pipeline for H-1B visa petitions, built for multi-tenant billing and compliance from day one How I work: Scope, deliverables, and cost are locked in before work starts. No mid-project surprises. I respond fast and stay reachable through the whole engagement, not just the first message. Ownership runs from first message to production handoff, not to a working demo. I'm available 40+ hours a week. Message me with what you're trying to solve, and I'll come back with a scoped approach before we talk price.
