I will build a simple custom web app or automation tool for you


About this gig
Need a small tool built fast, functional, and without the overhead of a big dev agency? That's exactly what I do.
I build lightweight web apps, trackers, generators, and automation scripts using Python and React Native/Expo. Recent examples: an AI-powered training plan app that generates personalized ultramarathon schedules via an LLM API, and a self-contained party word-game app built and deployed entirely from scratch.
I'm not a huge dev shop I'm one person who ships working things quickly, without padding the scope or overengineering. If you need a calculator, a tracker, a scoring system, a small internal tool, or a simple automation script that saves you manual work, this is for you.
What I can build:

- Small multi-feature apps with clean, functional UI
- Automation scripts (data processing, file handling, repetitive task automation)
- Simple integrations with APIs (including AI/LLM APIs)
- Mobile-friendly web apps (React Native/Expo experience)

- A clear description of what the tool should do
- Any specific inputs/outputs you have in mind
- Reference examples if you have them (a similar tool, a

FAQ
Can you host the app for me long-term?
Basic/Standard packages include delivery as a working link during the project. Premium includes basic hosting setup. Ongoing hosting/maintenance can be arranged separately.
What if my idea is bigger than what's listed in Premium?
Message me first with your requirements and I'll send a custom quote.
Can you work with an existing codebase?
Yes, for bug fixes or feature additions — just share the repo/files and I'll scope it before we start.
