sanchesfree - Overview
Alexander Gusev
Technical Founder / CTO — I build products from zero to production: architecture, backend, DevOps, and everything in between.
Based in Russia · Working remotely worldwide
What I do
I take business ideas and turn them into working products. Not just code — the whole thing: infrastructure, integrations, analytics, automation. Currently focused on e-commerce, AI-powered tooling, and micro-SaaS.
Core stack: PHP, Python, TypeScript, Go, Rust · 1C-Bitrix, React · MySQL, PostgreSQL, ClickHouse · Docker, CI/CD, Linux · OpenAI, Claude, LLM integrations
Open source contributions
I actively contribute to open source projects across different ecosystems:
- umputun/revdiff — TUI diff reviewer for Claude Code. 5 PRs, 3 merged:
- Layout-agnostic keyboard bindings — hotkeys work regardless of active keyboard layout (Cyrillic, Greek, Hebrew)
- Untracked/staged file support — toggle untracked files in the file tree
- Kaku terminal support — added split-pane overlay detection for Kaku (WezTerm-based terminal)
- mikeyobrien/ralph-orchestrator — Contributing to multi-agent AI orchestration framework

Business impact
Beyond writing code, I understand the business side:
- Grew e-commerce sales by 40% in one month through A/B testing, dynamic merchandising, and automated pricing
- Built a metrics collection system (sales, user behavior, ad spend, net margin) that drives automated pricing and merchandising decisions
- Launched multiple products from scratch — from server setup to first paying customers
