Senior Full-Stack Developer | Laravel/PHP, APIs & Modern Web

Senior software engineer with 20+ years of hands-on development experience, based in Kaunas, Lithuania.

I build and ship production web applications end-to-end: robust backends and APIs, clean data models, admin tooling, integrations, and polished frontends when the product needs them. Strongest on Laravel/PHP, MySQL/PostgreSQL, REST APIs, CMS platforms (October/Winter CMS, WordPress/WooCommerce), plus React/TypeScript where a proper SPA makes sense. Also experienced with payments/wallets and API integrations (including BVNK/OpenPayd-style flows).

How I work:

• Clear scope, practical architecture, and maintainable code

• Fast delivery with AI-assisted implementation and careful human review

• Security, correctness, and handover documentation first

• Fluent English (IELTS 8.5, EFSET C1/C2); comfortable overlapping EU / DACH timezones

Certifications: IELTS 8.5 (Oct 2016); Google AI Professional Certificate; Google AI Fundamentals (Coursera); EFSET C1/C2.

Typical work: custom web apps, API integrations, e-commerce/CMS features, automation, and ongoing product maintenance.
