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.

6000 USD Real estate and art sales platform with booking and payments.
Web Programming
LibraArte is a web platform built for a villa owner who also sells artworks. The project evolved from a simple website into a full-featured CMS and booking system. The frontend is implemented with Vue.js and Inertia.js, while the admin panel is built using Filament.
The system includes villa booking management, artwork catalog and sales, blogging, static pages, SEO configuration, additional services, and order handling. Payment processing is integrated via Stripe, and a calendar export was added for an external property management agency.
… The project is currently in active development and demonstrates complex business logic combined with a flexible admin interface.
Stack: Laravel, Vue.js, Inertia.js, Filament, Stripe
Result: Scalable CMS-based platform for real estate rentals and art e-commerce

2500 USD Website and mini service-booking system for a psychotherapist
Web Programming
The project was built to create a warm, calm, and trustworthy online presence. I proposed the design concept and developed both the public website and a custom admin panel using Laravel and Vue (Vite).
The site goes beyond a simple presentation page and includes blogging, static content management, and a services module with a checkout flow. Special attention was paid to SEO structure, editable content, and flexible media handling, including PDF uploads for qualifications and certificates. Email templates and key site texts are fully manageable from the admin panel.
… Stack: Laravel, Vue (Vite), Admin Panel, SEO, Mail
Result: Deployed psychotherapy website with blog, services, checkout, and flexible content management

1000 USD Car rental website with SEO-focused structure and dual theme
Web Programming
The project started as a simple landing page request, but after analyzing competitors, the concept evolved into a full-featured car rental website. The client provided a light-themed template, for which a matching color palette was selected and extended with a dark mode, implemented as a dual light/dark theme.
The platform was built using Nuxt, allowing the site to scale beyond a landing page. The final structure includes a car listing, individual vehicle pages, and additional content pages designed for SEO and organic traffic growth.
… Special attention was given to SEO-friendly architecture, ensuring that listings and car pages are properly structured and indexable.
The project is currently paused, as further development requires an admin panel for content management, which the client is not yet ready to invest in.
Stack: Nuxt, JavaScript, SEO, Light/Dark Theme
Result: SEO-optimized car rental website with listings, vehicle pages, and scalable structure

700 USD Mini e-commerce website for cinema-related products
Web Programming
The project was developed without templates or an admin panel. I designed the structure and UI based on competitor analysis, creating a clean, light-green themed interface suitable for the cinema snack niche.
The site was implemented as a Nuxt-based mini e-commerce application with a custom shopping flow. Product data is stored in YAML files on the filesystem, while cart and checkout logic are handled on the frontend using Pinia. Orders are saved as files on the server and email notifications were implemented and tested.
… The solution focused on simplicity, performance, and minimal backend complexity, matching the client’s real needs.
Stack: Nuxt, JavaScript, Pinia, YAML, Mail
Result: Deployed mini e-commerce site with catalog, cart, checkout, and order notifications

800 USD Landing page for Fitness Center
Web Programming
Fitness center landing website built from scratch
The project was developed without a formal technical specification - only a reference design provided by the client.
I rebuilt and adapted the template into a custom Vue-based frontend and later integrated a Laravel backend to support real business functionality.
…
During development, different approaches were tested (including Nuxt), and the final solution was chosen based on stability and client needs.
The Laravel backend enabled working contact forms and email delivery, which directly led to the first real inquiries from the website.
A redesigned contact section, customized beyond the original template, became one of the key features appreciated by the client.
Stack: Laravel, Vue.js (Vite), HTML/CSS
Result: Deployed website with functional contact forms and real customer requests

Bug fixes on the project - stage 3
The collaboration was generally fine: the contractor was in touch, the main functionality was implemented.
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.

Bug fixing on the project - stage 2
Everything is fine: a responsible approach and quick communication. The implementation of the idea turned out to be a bit more complicated than expected, but Oleksiy took all my edits into account without any problems and brought the task to completion. Thank you for the collaboration, we continue to work further.
