Hey, I'm Claudiu
I’m an engineer who builds apps and AI workflows: shipping real products, automating the busywork, and constantly learning what works.
Who Am I?
Engineer by day, builder by night. I build apps with AI and design workflows that automate the busywork: real iOS apps, web tools, and automations. I’m constantly learning what AI can actually do well, and I share the journey publicly on X while balancing a full-time job and family. I believe in shipping over perfection.
Between the 9–5 and family time, I carve out hours to build products that solve real problems, using AI to move faster. Prompt Eval helps developers test and compare LLM prompts. GiftEasy helps people find thoughtful gifts quickly. My Subscribe and Mood Fast are iOS apps for subscription tracking and daily well-being. SubRadar is a growth tool for discovering relevant Reddit conversations. Alongside the apps, I build AI workflows and automations that take the repetitive work off my plate, and I’m constantly learning what AI does well (and where it doesn’t). Everything I learn and ship, I share openly on 
Apps &
Projects
Real products I ship with AI.
Prompt Eval
An AI tool to test, score, and compare LLM prompts side by side, so you ship prompts that actually hold up in production.
Overburn
ccusage tells you what you spent; Overburn tells you what you shouldn't have — a local audit of your Claude Code logs that turns wasted spend into fixable line items.
Loop Kit
A plug-and-use AI agent loop harness — context hygiene, safety brakes, and maker/checker verification so agents finish real tasks instead of drifting.
GiftEasy
A web app that helps you quickly find thoughtful gift ideas for the people you care about.
My Subscribe
An iOS app to track and manage all your active subscriptions in one place and save money.
Mood Fast
An iOS app designed to help you improve your day-to-day mood with quick, structured check-ins and actions.
SubRadar
A Reddit scraping tool I built to discover relevant posts where my apps can genuinely help, staying within platform rules.

Having a draining 9-5 job while pursuing side projects is challenging, especially with a family you don't want to neglect. I feel there aren't enough hours in the day and need more.
Hey @steipete, Apple should definitely give you a percentage of the Mac Mini sales since you’ve contributed to them for the last months.
Everyone talks about AI. Even the CEOs that have no idea on how to actually use it.
Freelancing for some extra bucks doesn't seem such a bad idea now.
I really hope people would start using Telegram more than WhatsApp.
You can use ccusage with Claude to see what you spent. But if you want to know what you shouldn’t do or have, use overburn. npx overburn. Try it out with your Claude Code sessions.
