Hey there I'm a full stack developer working across web, mobile, frontend, backend, and cloud. I specialize in React, Next.js, React Native, Flutter, Node.js, Django, Laravel, and modern cloud environments. With over ten years of experience, I help clients turn ideas into fast, stable, and scalable products across mobile and web. I write this myself, not AI. My main focus areas - Cross platform mobile apps using React Native and Flutter - Modern web apps using React and Next.js - Backend development with Node.js, Nest.js, Django, Laravel, and ASP.NET - Cloud deployments on AWS, GCP, and Vercel - Clean architecture and scalable full stack systems Real world features I have delivered - Deep linking, push notifications, geo location, advanced navigation - In app purchases, subscription systems, Stripe, payment logic - Real time chat, social features, dating features, live updates, sockets, Firebase - AI integrations using GPT, custom AI APIs, and ML powered workflows - Admin dashboards, analytics, reporting, CMS tools - Ecommerce platforms, marketplace flows, checkout systems - 3D experiences with Three.js and react three fiber - Blockchain integrations for mobile and web when required Industries I have supported range from social platforms to healthcare, ecommerce, finance, enterprise tools, SaaS products, and internal company systems. I build MVPs from the ground up and also join existing codebases to fix issues, refactor structure, or deliver high priority features. Because I understand both frontend and backend along with mobile, I create solutions that work together as one complete product. I work independently, communicate clearly, and focus on writing clean and maintainable code that is ready to scale. If you need someone who can handle frontend, backend, mobile, and cloud in one place, I would be happy to hear about your project. Thanks for reading.

➡️My App Store Optimization earned the #1 ranking on the App Store Games - Trivia category in under 1 month for DAFUQ, a previously unranked app. I’ve worked with 150+ apps of all sizes, from startups to global brands like Hard Rock and MGM, achieving impressive results. My experience includes working on more than 15 top-100 apps, with notable examples like BetMGM Sportsbook (#4), Stadium Live (#9), Hard Rock Neverland Casino (#43), Timeleft (#55), Vivino (#38), Qmee (#20), Stronger (#37), DMV Genie (#88) Novel Effect (#47), Minutes (#57), Sole Supplier (#88), DMV Genie (#88), Sole Supplier (#90), and more. [ DATA-DRIVEN APPROACH ] These results come from a transparent, data-driven approach that focuses on improving keyword rankings on both Google Play and the App Store, improving organic downloads, conversion rates, retention rates, app ratings, and ultimately work to grow in-app purchase and subscription revenue. [ INDEPENDENT FREELANCER – I DO ALL THE WORK MYSELF ] Let's set up a free, 30‑minute video screenshare call 📞 to discuss how I can help your app achieve long‑term organic growth. Just send me a message, and I’ll share my calendar 📅 via Upwork. [ QUANTIFIABLE SUCCESS STORIES ] • Increased 21Moves’ monthly subscription revenue from $500 to $10,000 in just 3 months. • Boosted Qmee’s organic downloads from 13,000 to over 70,000 per month in 2 years. • Launched an ASO strategy that generated over $100,000 in monthly revenue. • Scaled apps to earn more than $300,000 per month. [ MOBILE APP MARKETING SPECIALITIES ] • ASO Metadata Optimization • Keyword Research • Cross-Localization (Japanese, Korean, French, etc.) • 7-Figure Apple Search Ads (ASA) Ad Campaigns • App Store Screenshots • App Preview Videos • Custom Product Pages (CPP) • Product Page Optimization A/B Testing • Conversion Rate Optimization (CRO) • App Ratings & Reviews Growth • In-App Events • Push Notifications & In-App Messaging Drip Campaigns • App Onboarding User Flow • User Retention Strategies • In-App Purchases & Subscriptions • App Development Feature Roadmaps [ NO PREDATORY TACTICS ] I can't stand agencies that fail to deliver on their promises. Too many make excuses like shifting market conditions, algorithm updates, low budgets, or increased competitor spending, rather than taking responsibility and adapting their strategy. Their focus is often on extracting as much money as possible before clients realize the strategy isn’t working. I don’t operate that way. My approach is transparent, data-driven, and built around real results, not empty promises. [ YES TO DATA ] I don't pretend to have superhuman intuition. I know how to find, understand, and apply ASO data to create and improve your app store product page. How to measure the impact of the ASO efforts is just as significant, so we're confident in the effects of the ASO efforts. No, "it sounded good" is not a sufficient explanation. Whether you’re an indie developer or a large studio, my ASO strategies can help you reach more users, improve conversion rates, and build long-term organic growth. Let’s talk about how I can help your app achieve its full potential.

Many developers are using AI tools now. The difference is knowing how to use them without creating messy, fragile software. I'm a Senior Full Stack Developer with 15+ years of experience building web, mobile, SaaS, and AI-powered applications for companies like Verizon, Cigna Healthcare, and Corxly. My background is very hands-on. I've worked on enterprise platforms, healthcare mobile apps, SaaS dashboards, backend APIs, cloud deployments, and AI automation systems. I'm comfortable owning the full product lifecycle - architecture, frontend, backend, integrations, deployment, and long-term maintenance. Recently, a big part of my work has been using AI tools like Claude, Cursor, and ChatGPT to speed up development. I don't treat AI as a replacement for engineering experience. I use it as a force multiplier for planning, coding, debugging, refactoring, testing, and documentation. For example, on Corxly, I helped build an AI-powered productivity SaaS platform with a scalable dashboard, workflow automation, voice-to-task features, and real-time productivity insights. The platform grew to 25k+ users and around $400k ARR. That kind of work requires more than just writing code quickly - it requires clean architecture, good product judgment, and the ability to keep the system stable as it grows. That's where I bring the most value. For startups, I can act as the senior technical person who helps move fast without overbuilding. For established teams, I can jump into existing systems, understand the architecture, clean up issues, and ship features without creating more technical debt. My main stack includes React, Next.js, React Native, Node.js, Python, TypeScript, PostgreSQL, Supabase, AWS, AI APIs, automation workflows, and modern DevOps tools. If you need someone who can build quickly, communicate clearly, and make practical technical decisions, I can help you turn an idea or messy codebase into a reliable product.
