Slava Weber

Senior full-stack web engineer, 13+ years shipping production websites and web applications end-to-end. For ten years (2016-2026) I worked remotely, as an independent contractor, for a German digital agency, 4eck Media, where I grew from front-end developer to senior full-stack developer and technical owner of the client platform the agency’s project work is built on.

What I owned there: a Dockerised, Composer-managed WordPress platform (custom ACF/Gutenberg block library, Vite/Vue 3 build, GitLab/GitHub CI/CD, Coolify) that became the foundation of 50+ agency sites; client briefings and site blueprints; the hardest parts of delivery (web apps with real logic, headless CMS, WordPress Multisite, custom API integrations such as booking systems, migrations of 1,000+ pages incl. Typo3 to WordPress); pre-release review against a 10-tool checklist (Core Web Vitals, WCAG 2.2, security headers, structured data, AI-readiness). I also worked full-stack in Laravel + Inertia + Vue 3/TypeScript on a large German e-learning SaaS (20+ engineers) and led its Laravel 11 to 12 / Inertia v2 modernisation.

AI, by dates and artifacts: coding assistants since 2022; in 2025 I evaluated coding agents from several vendors and standardised the team on Claude Code; from March 2026 the team shipped through the agent harness I built (Agent Skills, path-scoped rules, project memory, a self-review gate), running in 15 repositories. Separately I designed, led and accepted against evidence an LLM system in Python + C++: typed tool contract, hybrid retrieval over a knowledge graph, guardrails, an eval harness; the code was typed by coding agents under my direction. Since September 2026 I publish repositories where the core module is written by hand: github.com/slav-weber.

Format: remote only (Kyiv, EU time zone). Contract / B2B with a foreign company, 80+ hours a month, invoiced as a Ukrainian sole proprietor; from 30 EUR/hour on a long-term contract, from 42 EUR/hour for separate tasks. Not considering on-site or hybrid. Currently open to offers, not in active search. English has been my working language for the last ten years. Client names, live links and a signed reference letter are in the CV I send directly.
