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

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.
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.
