How I designed the execution engine, node system, variable resolution, and streaming for a visual AI workflow tool.

An open invitation to developers who want real AI engineering experience — how to contribute, what skills you'll gain, and what the project still needs.

A visual tool for chaining LLMs, web search, RAG, and more into real AI workflows — no code required to run them.

How I built the multi-provider LLM layer — routing, streaming, token tracking, cost estimation, and why abstraction matters more than people think.

A simple email system helped me reduce churn, recover abandoned checkouts, and bring old users back.

The stack i keep coming back to when i want to ship fast, keep costs low, and still build something serious.

A few things I keep coming back to when building real AI products.

I built mouse gesture control into Velin AI — draw an S, Circle, or Triangle with your mouse to trigger AI actions invisibly and hands-free.

The stack I use to keep infra and tooling costs near zero while still shipping real products.

The stack I use to build AI products that are fast, reliable, and actually shippable.

How I built my personal site and added a blog.

What i did for Velin AI and other products to get indexed, get found, and start bringing in users.

AI engineering, SaaS building, dev workflow, prompt design, infra, and product notes from the build.
