Profile Description

I help businesses turn ideas, manual processes, and outdated systems into modern web applications, mobile apps, SaaS products, and AI-powered business solutions.

With 5+ years of software development experience, I work across the entire product development lifecycle — from planning and architecture to frontend, backend, mobile development, API integrations, AI implementation, deployment, and ongoing improvements.

What I can build for you:

• AI-Powered Applications & Integrations
AI features, AI assistants, intelligent workflows, LLM integrations, automation, and custom AI-powered business solutions.

• Business Automation & Custom Systems
Automate repetitive processes, connect your existing tools, and build custom systems that help businesses operate more efficiently.

• SaaS & Web Applications
Customer portals, dashboards, CRM systems, management platforms, marketplaces, internal tools, and complete SaaS products.

• Mobile Applications
Cross-platform mobile applications for iOS and Android using modern frameworks and technologies.

• Backend & API Development
Secure and scalable APIs, databases, authentication, third-party integrations, business logic, and backend systems.

My technical experience includes:

Frontend
React, Next.js, TypeScript

Mobile
Flutter, FlutterFlow, React Native, Expo, iOS, Android

Backend
Node.js, NestJS, Python, FastAPI

Databases & Cloud
PostgreSQL, MongoDB, Firebase, Supabase, AWS, Railway

AI & Integrations
OpenAI, Google Gemini, AI APIs, LLM integrations, workflow automation and custom AI features

Other Integrations
Stripe, RevenueCat, Google Maps, Google Places, Zoom, WebinarKit and other third-party APIs

Why work with me?

I don't just focus on writing code. I focus on understanding what the business actually needs and building the technology around that goal.

Whether you already have an existing application that needs improvements, a product that needs to be built from scratch, or a business process that needs to be automated, I can help take it from concept to a working solution.

I'm comfortable working independently, collaborating with existing teams, taking ownership of technical decisions, and working on projects where multiple parts of the system need to work together.

I've worked on applications and systems involving areas such as fintech, logistics, warehouse workflows, SaaS, CRM, business management, AI, and mobile applications.

If you have an idea, an existing product, or a process that you believe could be improved with software or AI, feel free to message me.

Let's build something that actually solves the problem — not just another piece of software.
