Middle Web3 JavaScript && Solidity Developer
I build Web3 systems, smart contracts, AI tools and automation products. My focus is the full path from architecture and implementation to testing and reliable deployment.

I design and build complete products: from interface and architecture to smart contracts, backend systems and deployment

01Technical stack
Tools follow the problem · Fundamentals stay
The stack is broad because the products are broad. The core discipline stays the same: clear boundaries, measurable behavior and boring failure modes.
02Contact
Have a hard product or system to build?
Send the context, constraints and desired outcome. I am especially interested in Web3 infrastructure, AI products, automation and ambitious interfaces that need real engineering.
03Selected work
Real systems, not decorative demos
A cross-section of products built across Web3 infrastructure, AI tooling, automation, native apps and visual systems.
04What I do
From first principle to production behavior
I work across the stack, but the goal is always the same: a coherent product that works when the happy path ends.
05How I work
I like difficult systems and honest results
I am a Middle Web3 JavaScript && Solidity Developer focused on smart contracts, on-chain products, backend systems and automation. I can move from protocol details and database design to polished interaction and reliable deployment.
My strongest work happens in the seams: between a contract and a product, between a model and a real tool, between a beautiful interface and the failure state hiding underneath it.
Operating principlesGood engineering is a feature users can feel.
Root cause over symptom
If two patches fail, stop tuning and change the approach.
Safety is part of UX
Destructive, paid and irreversible actions deserve deliberate friction.
Ship the whole system
A beautiful screen without reliable operations is only a prototype.
06Broader lab
The archive is wider than the featured work
Dozens of local repositories cover earlier prototypes and focused experiments. They are grouped here by the capability they contributed.
