I help founders and product teams turn ideas into production-ready apps - web, mobile, and AI-powered - without burning months or budgets on the wrong approach.
430+ projects. 52,000+ hours on Upwork. $2M in delivered work. 100% Job Success Score. Top Rated Plus. Top 3% globally.
Those numbers did not come from small tasks or quick fixes. They came from building real products for real businesses, most of which are still running in production today. Several helped clients raise good amounts in funding.
I work with founders and product teams across the US, UK, and Australia. My core focus is full stack web development, mobile app development with Flutter and React Native, and AI integration systems built with n8n, Make, OpenAI API, LangChain, and RAG pipelines. More than 13 years of this work has taught me one thing: the most expensive decisions get made before a single line of code is written, and that is exactly when I get involved.
MOBILE APP DEVELOPMENT
Flutter and React Native for iOS and Android. Social platforms, booking systems, healthcare apps, AI-powered mobile products, and fintech tools. Clean architecture, complete App Store and Play Store deployment, and backends built to grow with your users, not break under them.
FULL STACK WEB AND SaaS DEVELOPMENT
React, Next.js, Node.js, Python, Drupal, Laravel. MVPs live in two weeks. Multi-tenant SaaS platforms in four to five weeks. Scalable architecture, third-party API integrations, admin dashboards, CRM systems, payment gateways, and documentation that holds up when the next developer opens the repo.
AI INTEGRATION AND INTELLIGENT SYSTEMS
n8n, Make, OpenAI API, Claude API, LangChain, RAG pipelines, AI agents, LLM-powered SaaS features, AI chatbot development. If your team is still handling manually what a system should be handling automatically, that is the exact problem I solve. Not a prototype. A production workflow that runs every single day and saves real hours.
TECH STACK
Mobile: Flutter, React Native, Swift, Kotlin
Frontend: React, Next.js, TypeScript, Vue.js, Tailwind CSS
Backend: Node.js, Python, Drupal, Laravel, PHP
AI and Automation: OpenAI API, Claude API, LangChain, n8n, Make, RAG, AI Agents
Cloud: AWS, GCP, Docker, CI/CD Pipelines
Database: PostgreSQL, MySQL, MongoDB, Firebase, Supabase
Payments: Stripe, PayPal, In-App Purchases
Integrations: REST APIs, GraphQL, Webhooks, Zapier, CRM Systems
HOW I WORK
Before any code gets written, I want to understand exactly what you are building and why. That conversation typically prevents weeks of rework and thousands in avoidable costs. I validate ideas, catch architecture mistakes early, and give you a realistic plan instead of an optimistic one.
Fast responses. Clear milestones. No inflated timelines. No surprise invoices.
Most of my clients have been working with me for years. That says more than any badge or metric.
If you have an app, a platform to scale, or a workflow to automate, send me a message. I will come back with a specific, honest plan.
