I am a full stack developer with 12+ years of experience building mobile and web apps. I have worked with startups launching their MVPs and businesses improving existing platforms handling everything from planning to deployment. If you are looking for someone who can take your app idea and actually turn it into a working, scalable product - You are in the right place. I work across Flutter, iOS, Android, web technologies and recently I have been helping clients with no code AI-powered solutions using Claude, Open Claw, Cursor, Replit, Lovable and many more to reduce the project cost. 🔹Over the years, I’ve built: – On-demand apps (food delivery, booking, taxi) – SaaS platforms and MVPs – Real-time apps with chat & notifications – AI-powered applications – E-commerce and marketplace solutions I’m comfortable handling the entire development cycle from UI/UX and frontend to backend, APIs, and deployment so you don’t have to manage multiple developers. Additional Services that i am offering: - 6 Months Free Maintenance once the apps goes live on apple store and Google play store - Ownership/iP rights from the day one uploaded on the Client Github - Regular Updates & Scrum meetings. - Following Agile Scrum Methodology from day one - Strictly adhering to the Apple Guidelines and Google Guidelines. - Taking Complete responsibility of Deployment on both Apple store and Google Play store. 👉 I believe in clear communication, meeting deadlines, and building long-term relationships, not just completing one project and disappearing. If you have an idea, or even a rough concept - I can help you plan it, build it, and launch it. 📩 Send me a message, and let’s discuss how we can bring your project to life.

🏆Most developers write the code and vanish. I stay. Building software since before smartphones existed - and still at the frontier today, shipping AI-powered apps, ERP systems, and mobile platforms that outlast the hype. In 18 years of building software, the one thing I've learned is that the real work begins after launch - when users push your app in directions you never planned, when scale exposes the corners you didn't know existed, and when the business evolves faster than the original spec. That's exactly where I show up, not just at the start. I build in the AI era the same way I've built for nearly two decades - with purpose, with ownership, and with a long-term eye on what your product needs to survive and grow. Not just what looks good in a demo. What I Build 🔹AI Applications – LLM integrations, automation, smart workflows 🔹Mobile Apps – Flutter & React Native (iOS + Android) 🔹Web & SaaS Platforms – React, Next.js, Laravel, .NET 🔹ERP / CRM / POS Systems – Custom business platforms 🔹APIs & Automation – Seamless system integrations What makes me different: Anyone can write code. Fewer can architect a system that scales. Even fewer stay invested in your success after the invoice is paid. I've delivered 80+ projects across healthcare, logistics, fintech, e-commerce, education, and enterprise - and the clients who come back aren't coming back because I was the cheapest option. They come back because when something needed fixing at 11pm before a client demo, I was there. A few things I've shipped: 📌 RunTailor Mobile App - two-sided marketplace connecting customers with tailors and boutiques, live on Play Store and App Store 📌 AIMS360 Apparel ERP - end-to-end fashion industry ERP covering design, production, inventory, and order management for apparel businesses at scale 📌 Stellify POS - full-featured point of sale system built for retail operations, handling transactions, inventory, and reporting in real time 📌 AuditXtra Mobile App- mobile audit and compliance app enabling field teams to conduct inspections, capture evidence, and generate compliance reports on the go 📌 UiPath Custom Activity (RPA) - enterprise-grade C#/.NET automation development, 5-star reviewed on Upwork 📌 ERP & CRM Platforms - custom enterprise systems replacing legacy software for mid-size businesses 📌 FedEx-Integrated Shipping Platform (API Integration)- real-time parcel tracking and logistics web application Technologies & Tools 🔹Frontend: React.js · Next.js · Angular · Vue.js · TypeScript · TailwindCSS · Bootstrap · Material UI 🔹Backend: Node.js · NestJS · ASP.NET Core · Laravel · CodeIgniter · PHP · CakePHP · REST APIs · GraphQL · WebSockets 🔹Mobile: Flutter · FlutterFlow · React Native · iOS · Android · Deep Linking · Push Notifications · Firebase · In-App Purchases 🔹Database: SQL Server · PostgreSQL · MongoDB · MySQL · Firebase · Supabase · Redis 🔹Cloud & DevOps: AWS · Azure · Google Cloud · Docker · CI/CD · S3 · Cloud Deployment 🔹AI & Integrations: OpenAI · ChatGPT API · LLM Integration · Stripe · PayPal · Twilio · SendGrid · FedEx API 🔹Business Solutions: ERP · CRM · POS Systems · SaaS · MVP · E-commerce · WooCommerce · Marketplace · Admin Dashboards · LMS 🔹Languages: C# · PHP · Python · JavaScript · TypeScript · Java · Kotlin · Dart My promise to you: I will tell you what your product actually needs - not what sounds impressive in a proposal. I will flag risks before they become problems. I will be reachable, honest, and invested from day one to long after go-live. If you're building something in the AI space, launching a mobile app, modernising your enterprise systems, or starting from a napkin sketch - let's talk. 📩 Message me or hit Invite - I respond within hours, not days.
