About this gig

Hi, I am Sem. I build web and mobile apps, and for the last years I have worked

almost only with AI tools and AI-powered features. That is what makes me fast

and affordable.


I help founders, creators and small businesses turn an idea into a real product:

a custom app, an MVP, a dashboard, an internal tool or a web app.


This is not a template. Your project is planned, designed, coded and deployed

around your actual business goal.


Tools I work with: Replit, Claude and Codex


What you can request:

- Custom web or mobile application, or an MVP

- Dashboard, SaaS idea, client portal or internal tool

- Frontend and backend structure

- AI chatbot or OpenAI and Claude powered features

- Deployment and handover


My process:

1. Concept, sitemap and feature definition

2. UI direction and screen structure

3. Frontend build, every page users see

4. Backend logic and core functionality

5. Testing, refinement and optimisation

6. Deployment and handover


Send me a message with your concept. I will tell you honestly what it needs

and what it costs.
