CV
Looking for a Senior Developer who builds scalable systems, not just working code?
With over 18 years of professional experience in the IT industry - including a decade of leadership at international companies like OpenText and MicroFocus -I bring a high-level architectural mindset to every web development project.
My mission is to create technologically efficient, well-structured systems that solve real business problems. Whether you need a high-performance e-commerce platform or a custom SaaS application, I specialize in the TALL/VILT stacks (Laravel, Vue.js, Nuxt) to deliver fast, SEO-optimized, and maintainable solutions.
What I bring to your project:
Full Stack Expertise: Expert-level Laravel (API, complex logic, queues) and Nuxt/Vue (SSR, SPA, composition API).
Performance-First Approach: I build for speed, consistently achieving Lighthouse scores of 90+ for performance and SEO.
Senior-Level Reliability: 10+ years of experience leading teams means I understand deadlines, clear communication, and clean code architecture.
Enterprise Background: Deep experience with Docker-ized production setups, CI/CD (Jenkins/Ansible), and complex database optimization (PostgreSQL/MySQL).
Proven Technical Skills:
Backend: Laravel (FilamentPHP), PHP, Node.js.
Frontend: Vue, Nuxt, TypeScript, Tailwind CSS, Livewire.
DevOps/DB: Docker, AWS, Jenkins, PostgreSQL, Oracle, MSSQL.
Integrations: API expertise with payment gateways (PayPal, Wise, WayForPay) and logistics (NovaPoshta, UkrPoshta).
I am available for both long-term cooperation and complex technical tasks. Let’s build something that scales.
Write to me if you need an expert developer who understands the big picture.

Bug fixes on the project - stage 3
At the same time, after the changes were made, some things worked unstably or worse than before. Discrepancies arose on these points - they were considered as separate tasks for payment, although they appeared to be a result of the changes made.
Also, the deadlines were significantly shifted from the initially agreed ones.
I recommend clearly defining the criteria for task completion at the start, the approach to testing (especially without staging), and what is included in corrections after submission.
