Warsaw, Mazowieckie, Poland
I build what others can't buy off the shelf. At 19, I've independently designed and deployed production-grade systems that handle real money, real users, and real threats — without relying on third-party APIs or ready-made solutions. What I've built: → Anti-fraud system — real-time transaction scoring, behavioral analysis, automatic flagging of suspicious activity with full user history forwarded to manual review panel. Decision engine: approve / block / reverse. → Crypto payment infrastructure — fully custom, zero external APIs. BLIK-to-crypto flow: user verification, payment processing, automatic balance updates, LTC withdrawals. Built and deployed solo. → End-to-end encrypted data transmission — proprietary E2E encryption technology for secure transfer of sensitive financial data between system components. → Telegram bots & automation — custom bots integrated with payment and fraud systems. → Full-stack web development — advanced frontends, REST APIs, backend architecture, endpoints — built from scratch. My approach is never a template. Every client gets a detailed needs analysis, a custom mind map, a project skeleton reviewed together — then full execution with ongoing consultation. I'm looking for: partners, resellers, direct clients and investors across Europe. 🔷 EXPERIENCE — Cybersecurity & Software Development Founder & Lead Developer — Independent / Stealth 2023 – present Designed and deployed proprietary anti-fraud engine with real-time risk scoring and manual review panel Built custom E2E encryption technology for financial data transmission Developed full crypto payment system (BLIK → crypto) without external APIs — solo Delivered full-stack projects: frontend, backend, REST API, database architecture Clients receive individual project skeleton, mind map and full consultation throughout development 🔷 EXPERIENCE — Crypto Trading & Exchange Founder & Operator 2023 – present Operating automated crypto buy/sell/exchange platform built entirely in-house Integrated BLIK payment processing with automatic crypto settlement Built and maintain fraud detection layer protecting every transaction Managing client verification, balances, withdrawals and dispute resolution 🔷 SKILLS Cybersecurity · Anti-Fraud Systems · Encryption · JavaScript · TypeScript · Node.js · React · C++ · REST API · Backend Development · Frontend Development · Telegram Bot Development · Crypto Payments · System Architecture · Full-Stack Development · NIS2 · DORA · Fintech · 📩 Open to serious inquiries.
