Senior AI Engineer with 12+ years of experience building multi-agent AI systems, RAG pipelines, workflow automation, and full-stack SaaS platforms using LangChain, CrewAI, n8n, and OpenAI, delivering scalable, production-ready solutions from architecture to deployment. I personally lead every engagement, backed by a vetted team for when projects need to scale. Across 36 Upwork contracts (with 100% Job Success Score) and 300+ projects throughout my career at AllZone, Fieldforce, Allshore, and AAJ Technologies, I've built systems that ship on time and hold up in production. What I build: → Multi-agent AI systems - LangChain, CrewAI, AutoGen, RAG pipelines, and LLM-powered workflows built for production → Automation infrastructure - n8n, Make, Zapier, and custom integrations that eliminate manual bottlenecks → SaaS backends & APIs - Node.js, .NET, REST/GraphQL, Stripe, and complex third-party integrations → Full-stack web apps - MERN, Next.js, PHP, Laravel, with scalable cloud architecture on AWS and Azure Recent work: → Architected a CrewAI multi-agent system for a patent-pending fintech platform, 330+ hours, 5-star review → Rescued a stalled .NET + Stripe + Persona + Twilio build after the original developer quit, delivered on deadline in 500+ hours, and again, a 5-star review → Built an AI-powered FDA Label Compliance System, automated a regulatory review process that previously required hours of manual work For projects that need dedicated full-stack depth, standalone MERN builds, .NET enterprise systems, or PHP/Laravel backends, my team handles those end-to-end with the same standards and ownership model. Who I work best with: Founders and technical leads who want a senior engineer that communicates clearly, moves fast, and takes full ownership from architecture to delivery. Let’s connect and build something exceptional!

With over 12+ years of extensive experience, I specialize in developing custom web solutions and search engine-optimized web applications, seamlessly integrating them into mobile applications as well.

20+ years. Dozens of products shipped. One consistent focus is building systems that don't break when your business grows. If you're a founder or product team looking for a technical lead who can guide decisions, not just execute tasks, that's exactly what I do. I work with startups, scale-ups, and established businesses to take ideas from early concept through to stable, scalable products. Whether that's an MVP you need to validate quickly, a mobile app ready for real users, or a SaaS platform built to grow, I stay closely involved on the technical side while keeping the broader product direction on track. 𝗪𝗵𝗮𝘁 𝗺𝗮𝗸𝗲𝘀 𝘁𝗵𝗶𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 Most developers will build what you ask for. My job is to make sure what we build is the right thing and that it won't need a full rebuild when your user base grows or your requirements change. That means asking the right questions early, flagging trade-offs before they become expensive problems, and making sure every technical decision connects back to your business goals. 𝗪𝗵𝗮𝘁 𝗜 𝗯𝘂𝗶𝗹𝗱 • Mobile Applications - iOS, Android & Cross-Platform • Full-Stack Web Applications & SaaS Platforms • AI Features & LLM Integrations (RAG, chatbots, OpenAI, Claude, semantic search) • MVP Builds from idea to working product, fast • API Development & Third-Party Integrations • Backend Architecture built for scale • Technical Strategy & Product Planning for founders 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 𝗜'𝘃𝗲 𝘄𝗼𝗿𝗸𝗲𝗱 𝗶𝗻 Healthcare & Mental Wellness · Fitness & Sports · Real Estate · Freight & Logistics · Education & E-Learning · Food & Beverage · Financial Services · Social & Community Platforms Each of these industries comes with its own operational and technical challenges. Having worked across all of them means I can move faster, ask better questions, and avoid the mistakes that slow teams down. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 I value long-term collaboration over quick handoffs. Many of the clients I've worked with have stayed through multiple development stages, because when a team understands your product deeply, the work gets better and faster over time. My working style is direct and transparent. You'll always know where things stand, what decisions are coming, and why I'm recommending what I am. No technical jargon for its own sake, just clear communication that keeps the project moving. 𝗛𝗼𝘄 𝗺𝘆 𝘁𝗲𝗮𝗺 𝗶𝘀 𝘀𝗲𝘁 𝘂𝗽 (𝗳𝘂𝗹𝗹 𝘁𝗿𝗮𝗻𝘀𝗽𝗮𝗿𝗲𝗻𝗰𝘆) I am based in India, where I lead a development team I have built and managed over the years (Differenz System Pvt. Ltd). We also run a US entity, Differenz System LLC, and my partner Drishti C. in Los Angeles is your US-based point of contact when you prefer someone in a US time zone. You get a US business and US-hours communication when you want it, plus a senior, hands-on tech lead (me) and the delivery capacity of a full team behind the build. Every team member works under my direct supervision, and I remain your primary technical lead throughout. 𝗔𝗜 𝗳𝗲𝗮𝘁𝘂𝗿𝗲𝘀 𝗜 𝗯𝘂𝗶𝗹𝗱 𝗳𝗼𝗿 𝗰𝗹𝗶𝗲𝗻𝘁𝘀 I build production AI into web and mobile products: LLM and RAG pipelines (OpenAI, Claude, Gemini), chatbots and AI assistants, semantic and natural-language search, AI document processing and OCR, and recommendation engines. Shipped examples include Food Check AI, CLNSD, and Quick Payable (AI document automation). Every AI feature is built for real-world reliability, with output validation and human-in-the-loop review where the stakes are high, not a demo that breaks in production. 𝗔𝗜-𝗔𝘀𝘀𝗶𝘀𝘁𝗲𝗱 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗺𝗲𝗻𝘁 I use AI tools like Claude as part of my development workflow. Not as a shortcut, but as a way to move faster without cutting corners. In practice, that means using AI to accelerate repetitive groundwork, explore approaches quickly, and pressure-test logic, while every piece of code that goes into a production system is reviewed, understood, and validated by me before it ships. I don't copy code blindly. AI handles speed. Experience handles judgment. The combination means you get faster delivery without the hidden technical debt that comes from unreviewed, auto-generated code. 𝗟𝗲𝘁'𝘀 𝘁𝗮𝗹𝗸 𝗮𝗯𝗼𝘂𝘁 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 If you're building any of the following, I'd like to hear about it: • A mobile app: iOS, Android, or cross-platform • A SaaS product or startup MVP • A scalable web application or backend system • A platform that's grown beyond its original architecture Send me a short brief describing what you're building and where you're stuck. I'll review it and come back with honest thoughts on approach, timeline, and what to watch out for.

𝗚𝗿𝗲𝗮𝘁 𝗔𝗜 𝗦𝘁𝗮𝗿𝘁𝘀 𝘄𝗶𝘁𝗵 𝗚𝗿𝗲𝗮𝘁 𝗗𝗮𝘁𝗮. The success of any AI application depends on far more than selecting the right language model. Reliable AI requires high-quality data pipelines, scalable infrastructure, intelligent retrieval, and production-ready architecture that delivers accurate results under real-world conditions. I help organizations build the data foundations behind modern AI products. My expertise combines Data Engineering, Retrieval-Augmented Generation (RAG), Machine Learning, Vector Search, and AI Infrastructure to transform fragmented business data into intelligent, searchable, and scalable systems. From enterprise knowledge platforms and semantic search to ETL pipelines, MLOps, document intelligence, and AI infrastructure, I design solutions that support long-term growth while maintaining performance, reliability, and operational efficiency.
