Full-Stack Developer | Web, Mobile, Cloud & Automation
Hi! I’m a Full-Stack Developer experienced in building, maintaining, debugging, and optimizing modern applications across web, mobile, backend, cloud, and automation.
I work with both new and existing projects and can help turn requirements into reliable, maintainable solutions. I’m particularly comfortable troubleshooting difficult issues, understanding existing codebases, integrating APIs, and improving application performance.
What I Can Help With
Web Development: React, Next.js, JavaScript, TypeScript
Backend Development: Node.js, Express, .NET, REST APIs
Mobile Development: React Native
Cloud & DevOps: Microsoft Azure, Azure Functions, Docker, Terraform
Database & Backend Services: Firebase, Dataverse, SharePoint
Automation: Power Apps and Power Automate
API Integration: REST APIs, third-party services, authentication, and data processing
Debugging & Optimization: Performance issues, API problems, frontend bugs, and existing application maintenance.
My Approach
I focus on understanding the actual problem before implementing a solution. Whether it’s a small bug or a larger application issue, I aim to identify the root cause, make the necessary changes, and ensure the fix doesn't break existing functionality.
I’m comfortable joining projects at any stage and working with existing code rather than requiring everything to be rebuilt.
If you need someone who can build, troubleshoot, integrate, automate, and improve your application, I’d be happy to help.

🏆 13+ years on iOS and Android, 5,500+ hours, 100% Job Success, Top Rated 🏆
I build AI powered mobile apps in React Native and Expo, plus the API and web dashboard behind them. When the framework runs out I write the native Swift or Kotlin myself.
Every cross platform app hits the same wall eventually. The camera needs a frame the library won't hand you. A background task dies the second iOS suspends the app. HealthKit or Bluetooth wants a permission flow no wrapper handles. Or the AI feature you just added makes the list stutter on a 3 year old phone.
That's the week your developer tells you React Native can't do that.
It usually can. Somebody has to open Xcode and write the module.
The second wall is quieter. The app ships, and then nobody can see inside it. No admin screen. No way to answer a support email. No place to read what the AI actually returned. That's when a second contractor gets hired for what was always one product.
I help founders and product teams ship one app to both stores, with the API and the dashboard that runs it. Not 3 contractors hoping the other 2 agree.

✔️ AI Features Inside An App That Already Has Users
OpenAI, Claude, Gemini, DeepSeek, or Apple's on device models. I shipped the AI winner prediction and the strike heat map inside FX1's MMA app, in Swift and SwiftUI. Live fight data and real time chat ran in the same codebase. A separate React Native contract ran on Apple Intelligence for 82 hours and closed at 5 stars.
✔️ React Native And Expo, One Codebase, Both Stores
434 hours on one React Native contract, plus 3 more on the record. TypeScript, Redux Toolkit, Zustand, React Query, and a build that actually signs.
✔️ The Web Half Of The Same Product
The REST or GraphQL API your app talks to, and the React or Next.js dashboard your team runs it from, so support can answer a customer or pull a refund without messaging you first. Node and Express, PostgreSQL, Supabase or Firebase underneath. One person on both sides. The phone and the browser never disagree about what a user is.
✔️ Native Swift, SwiftUI, Kotlin And Java When The Wrapper Won't Do It
889 hours in Swift for one client, across 20 months. Native modules, sensors, camera work. The screens that have to feel native.
✔️ The App That's Built, Live, And Breaking
Crashes, memory, a list that stutters, a release that won't go through. One client kept me on fixes for 3 years and 4 months.
✔️ App Store And Google Play, All The Way Through Review
TestFlight, App Store Connect, Play Console, signing, permission strings, privacy labels. Plus the resubmission when Apple comes back with a guideline number.

🎯 Most React Native developers stop at the bridge. I work the other side of it too, in Swift, SwiftUI, UIKit, Objective-C, Kotlin and Java. A native module is normal work here, not a rewrite quote.

I build web and mobile apps that are production-ready, not just functional.
3+ years of full-stack experience across fintech, AI SaaS, and business
automation. I've worked on real products with real users — an international
money transfer platform (Bless Payments), an AI-powered video editing SaaS
(Butter Studio), and a business automation dashboard (HEPCO). I know what
it takes to ship and maintain code at scale.
What I can help you with:
✦ Web apps — React, Next.js, TypeScript, Tailwind CSS
✦ Backend — Node.js, Express, Python, FastAPI, .NET/C#
✦ Mobile — React Native (certified)
✦ AI integration — Claude API, OpenAI, AssemblyAI
✦ Database — PostgreSQL, Supabase, SQLite, Drizzle ORM
✦ Infra — Docker, Azure, GitHub Actions, DigitalOcean
At Bless Payments I built authentication systems, payment gateway
integrations, and verification workflows for an international remittance
platform — security-first, cross-timezone, production-grade.
At Butter Studio I led full-stack development of an AI video editing SaaS
from the ground up — transcription pipelines, AI story extraction, EDL/FCPXML
export, and proxy file workflows.
I'm easy to work with. I communicate clearly, raise blockers early, and
I don't disappear mid-project. Whether you need someone to own a feature
end-to-end or collaborate with an existing team, I'm comfortable either way.
