I'm a developer and builder who uses AI as a creative partner to turn ideas into working products. Each project starts with a real problem — something people I know actually struggle with — and ends with something shipped and live.
The range spans education, health, personal finance, and developer tools. The common thread is making people more capable through thoughtfully-built software.

Your AI accountant for freelancers.
Freelancers spend hours tracking expenses, writing invoices, and guessing their tax bill. AgentBook handles it all — just chat naturally or use Telegram, and the agent does the bookkeeping.
Explore the human body like never before.
Anatomy is hard to internalize from flat textbooks. MedAtlas is an interactive 3D body explorer for pre-med students — navigate systems, structures, and spatial relationships with AI explanations alongside.
Where kids fall in love with math.
Students in grades 4–11 see math as abstract punishment. MWorld flips that by turning mathematical ideas — patterns, geometry, number theory — into something you can explore and play with. Intuition first, formulas second.
Smart support for young athletes.
Young athletes, coaches, and clubs lack unified tools for wellness, injury prevention, and training guidance. SafePlay+ brings it together — personalized, accessible, and built for the real pressures of youth sport.
Self-publishing, simplified.
Most aspiring authors give up before they reach readers — the process is fragmented, expensive, and opaque. BrainLiber Books guides writers from manuscript to marketplace using AI-assisted editing, design, and distribution.
Visualization for AI agents.
AI agents can reason and write — but when they need to show a chart, diagram, or spatial map, they go silent. Glyph is an agent-native visualization library: give any agent the ability to generate and render rich visuals across any framework.
About the builder
I believe the most interesting thing you can do right now is pair human judgment with AI capability — not to replace thinking, but to compress the distance between an idea and a working product.
Each project starts with a problem I or someone I know genuinely faces. I use AI as a creative and technical partner to go from zero to shipped faster than was ever possible for a single person. But the ideas, the judgment calls, the care about whether something actually helps — that stays human.
The work spans education, health, finance, and developer tools. The common thread isn't a domain — it's the belief that good software makes people more capable, and that capability should be accessible to everyone, not just those with the resources to hire a team.
More projects are coming. If something here resonates, I'd love to hear from you.
