about
Independent builder, Bratislava, working mostly after dark. The work splits into three categories — sometimes one bleeds into another, but the categories are real.

What I make
Crypto + signal infrastructure
AlphaFeed and SharpFeed are the live ones — AI-curated alerts that subscribers act on, real-money auto-traders behind them, both gated by paper-trading proof windows before any capital deploys. The thing I actually care about there isn't "AI in finance". It's the discipline around running automated capital deployment safely: kill switches, idempotent state, approval gates, daily heartbeats, restart-safe by construction.
Web — done well, one customer at a time
Receptiv is the paid service: custom websites for small Slovak businesses that need a real site without the agency price tag. Each one designed and built individually — no templates, no page-builder slop. Fixed price, fast turnaround, year-2 handoff direct to the customer's chosen Slovak host so there's no lock-in. Currently open for work.
Security + reverse engineering, on the side
I came up on the user side of the cheating community before I ever wrote one — paid customer, watched the games and the ecosystem long enough to learn how things actually break. PEX (a PE analyzer) and Evrima ESP (a Windows kernel-mode research project) are where that side shows up in code. Authorized assessment writeups live at /findings — the bug classes worth teaching, with targets anonymized.
How I work
Solo, async, honest about what I don't know. I prefer one thing shipped over four things half-built. Tests for safety-critical paths, light tests for everything else, no tests for ten-line one-off scripts. SQLite by default; Postgres only when SQLite stops being enough. Docker for anything that needs a daemon, plain rsync for anything that doesn't. Boring infrastructure, interesting product surface.
I try to write the kind of project writeup I wish other people wrote — the decisions that actually mattered, the tradeoffs, the bugs that taught me something. If you find a writeup here that reads like sales copy, tell me and I'll rewrite it.
Currently open to
- Receptiv work — Slovak SMB websites, €399 flat including year-1 hosting
and domain. Email
saxx@receptiv.devor any of the socials on the home page. - Authorized security work — bug bounty, paid pentest, RE consultancy. Web app and Windows-side both fine. Not interested in anything that requires bypassing anti-cheat or terms of service.
- Remote async collaboration on something genuinely interesting — crypto, prediction markets, low-level Windows / RE, automation infrastructure for small teams. Comfortable being the only engineer on a thing.
What I won't do
- Phone calls. Genuinely, none — async text only.
- Agency-style pretending to be a team I'm not.
- Anything that requires my legal name on a public surface.
- Crypto-token launches, NFT projects, growth-hacking schemes.
