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.

I build production-ready Claude-powered AI agents and automation systems that ship in weeks, not quarters and actually run in production. No demos, no proof-of-concepts that quietly die.

I help startup founders and businesses develop scalable Android & iOS mobile apps using Flutter, SwiftUI, and Kotlin. I always work as a product-focused mobile app developer, not just someone who writes code. I help you turn an idea into a clear, scalable, and launch-ready mobile product. Before development starts, I help you think through: • What should be included in the MVP • What should be avoided in the first version • Which tech stack makes sense • How the app should scale later • How to reduce development cost and time • How to avoid expensive rebuilds after launch Today, speed matters, and AI has changed how products are built. I use AI strategically across the development process to help you move faster without sacrificing quality. This allows us to prototype faster, reduce repetitive work, improve planning, and integrate AI-powered features directly into your app when needed. This means you can launch faster, test with real users sooner, and improve your product before competitors catch up. What I Can Help You With: • Flutter app development for Android and iOS • MVP development for startups • AI-powered mobile applications • App redesign and performance improvement • Backend integration and scalable architecture • Product strategy and technical planning • From idea validation to launch Why Work With Me: ✔ Top 3% Talent on Upwork ✔ 100+ mobile apps successfully launched ✔ $1M+ revenue generated through client products ✔ Experience with MVPs, SaaS products, marketplaces, AI apps, and growth-stage platforms ✔ Strong background in both development and product thinking Hiring the wrong developer can cost you more than money. It can lead to unnecessary features, poor user experience, slow performance, bad architecture, and a complete rebuild within 6 to 12 months. The right partner helps you build lean, move fast, and make smart decisions from day one. I also offer a free consultation to help you validate your idea, define the right MVP scope, choose the correct architecture, and understand what should be built now versus later. If we are not the right fit, I will tell you honestly. But if you are serious about building a mobile app that is fast, scalable, and built with the right strategy, let’s talk.
