I don’t learn from books. I learn by doing, by breaking things until they make sense. That’s how I taught myself DevOps, how I learned to build modern web products, and how I ended up running a quiet studio on the side.
At Hashira I make systems faster, cheaper, and safer. I moved a sprawling infrastructure from a costly cloud setup to a leaner stack, introduced Cloudflare tunnels and a hardened network fabric, deployed a Kong gateway, and reduced monthly spend by an order of magnitude without sacrificing reliability. I care about security because good architecture makes insecurity impossible, not because a vendor told me to.
I build user‑facing products too: React + Vite for client‑heavy experiences, Next.js when SEO and SSR matter, FastAPI for pragmatic backends, and Rust for parts that need to be fast and unforgiving. I run vanguards.studio, where we ship production sites for real businesses—real estate, automotive, and marketing teams who want results, not buzzwords.
I built Obscura, a privacy‑preserving mixer using ZK‑SNARKs with a distributed indexer and a live beta on Sepolia. It’s a side project that grew into a real system: circuits, verifiers, deterministic factories, and a public indexer API. It taught me more than any course could.
I work mostly alone. I sprint. I stretch when a problem demands it and I negotiate scope when it doesn’t. I mentor, I hire, and I push teams until they hit the finish line or we agree the work needs different support.
My approach is simple: start building, learn the hard parts on the way, and make systems that are honest—secure, simple, and quiet when they run. In five years I want to be leading teams and products, doing bigger things and finally taking a breather because the work I built is standing on its own.
