šÆ HOW I CAN HELP YOU
FULL-STACK WEB APPLICATION DEVELOPMENT
Launch scalable web products that convert users faster and support long-term growth. I build React, Next.js, Node.js, and TypeScript applications with architecture choices that have supported $1M+ in Upwork earnings and 100% Job Success.
AI AGENT AND OPENAI INTEGRATION
Add intelligent features that automate work, reduce manual effort, and create new product value. I integrate OpenAI APIs and AI workflows into existing platforms to accelerate delivery and turn ideas into usable AI-powered products.
MOBILE APP DEVELOPMENT
Ship iOS and Android apps that give users a smooth experience across devices and help you reach more customers. I develop with Flutter, React Native, Swift, and Kotlin, with proven experience delivering apps published to both Apple and Google app stores.
SAAS PLATFORM DEVELOPMENT
Turn complex ideas into secure, scalable SaaS products that are ready to monetize. I have built multi-tenant platforms with authentication, billing, APIs, and dashboards for startups and enterprise teams in as little as MVP timelines.
API AND BACKEND ENGINEERING
Increase system stability, speed up integrations, and support growth with robust backend foundations. I design Node.js, NestJS, Express, PostgreSQL, and cloud-based systems that handle real-world product demands across web, mobile, and AI features.

šš¼š š šŖš¼šæšø
I build in React, Next.js, and TypeScript to ship fast, maintainable web apps, then use Node.js, PostgreSQL, and AWS to keep the backend reliable and scalable. For AI features, I integrate OpenAI APIs and Cursor into workflows that automate tasks and add real product value. I also use Flutter when a project needs a polished cross-platform mobile app.
I build full-stack web applications with React and Next.js, integrate Node.js APIs, and deliver mobile app development with Flutter and AI development that scales.
