Hire the Best PDF Converters
in Ukraine

I build production web applications - SaaS platforms, B2B/B2B2C products, and custom tools - from frontend (Vue/Nuxt and React/Next) through backend (Node and Supabase), architecture through deployment. Recent work: two years on WeTransfer's flagship product (80M+ monthly users), and lead engineer roles on multiple SaaS platforms, including a Chrome extension with 170,000+ users. 🏆 Why clients hire me At WeTransfer, I spent two years inside a distributed product team on an application serving 80 million monthly users - refactoring core subscriber journeys, writing technical design docs for initiatives spanning multiple divisions, and running UX experiments that lifted conversion and retention, including a rework of a core feature that reduced churn by ~10%. I took part in the on-call rotation and shipped under real production pressure. That's where my standards for code review, testing, accessibility (WCAG), and deploying safely at scale come from. As lead engineer at Gaggl, a creator-hosted TV platform, I built the real-time backbone: Twitch chat and stream-metrics ingestion powering live interactive gameplay across 10+ show formats, an XP/leaderboard system driving repeat engagement, and a monetization feature (Reward Mode) with Wise-integrated creator payouts, serving 1,000+ creators with audiences from tens to thousands of viewers. At Glimpse - a Chrome extension with 170,000+ users, a 4.8⭐ rating, and a Featured badge on the Chrome Web Store, used by teams at companies like Amazon and The New York Times - I led a full architecture revamp: integrating new features, eliminating unnecessary re-renders, moving heavy computation off the critical path, and tightening Core Web Vitals (LCP, CLS, INP) on the marketing site. While SaaS is where most of my recent work lives, the same skills carry to custom builds: browser extensions, admin and internal tooling, scrapers, real-time systems, and gluing third-party services together cleanly. I take ambiguous product requirements and turn them into shipped, maintained features - and I tell you early when a requirement will cost more than it's worth. 🤖 AI-accelerated, senior-reviewed I work with agentic AI tooling daily (Claude Code, Cursor). Faster iteration, better test coverage, and more of the budget spent on architecture and product decisions instead of boilerplate. But every line that ships is reviewed, tested, and architected by me. Speed of AI with senior-engineer accountability. 🛠 Stack • Frontend: Vue 3 / Nuxt, React / Next.js, TypeScript throughout • Backend: Node.js (Express, Fastify, NestJS), REST APIs / gRPC / GraphQL, real-time (WebSockets), third-party integrations (payments, email, analytics) • Data: PostgreSQL, Supabase, MongoDB • Quality: Vitest / Jest, Playwright, accessibility (WCAG), feature flags (LaunchDarkly, Amplitude) • Infra: Docker, GitHub Actions CI/CD, AWS, GCP 🤝 How I work 8+ years of production experience. 6,000+ billed hours on Upwork. 20+ completed projects. 100% Job Success, Top Rated Plus - built on long-term client relationships rather than one-off gigs. Clear, proactive communication in fluent written English: daily async updates, honest estimates, questions asked before they become problems. Tested, documented changes following industry best practices. Whether you're at the concept stage or deep into an existing codebase, I'm happy to talk it through on a call before any commitment. Send me a message with a few lines about your project, and I'll respond with concrete thoughts on approach.

Hi! I’m an automation specialist with 5+ years of experience building smart, AI-enhanced systems using ZennoPoster and other tools. I help businesses automate complex workflows that require not just clicks and scraping — but real logic, decisions, and adaptability. 🧠 I specialize in: • Creating autonomous ZennoPoster bots powered by AI (e.g. GPT) • Integrating AI into workflows to make bots decide, adapt, and respond • Web scraping from dynamic and protected websites • Human-like emulation (mouse, keyboard, wait times, error handling) • GET/POST requests, APIs, Telegram bots, database connections • Building full-scale agent-like systems ⚙️ Tools & Tech: • ZennoPoster (advanced use with logic branching & modular design) • ChatGPT / GPT API integration • Regex, XPath, JSON, CSV, SQL • Telegram Bot API, Email Automation, SEO tools • Python (basic usage for local AI servers and LangChain testing) 🎯 Why work with me? I don’t just create scripts — I build smart systems that *learn, adapt, and scale*. You get automation that *thinks*, not just follows instructions. Let’s talk about how we can turn your manual processes into intelligent, scalable systems. Message me anytime — I’m ready to help.

Hello, and thank you for expressing interest in my work! I’ve been engineering websites on WordPress since 2010 and building dedicated e-commerce stores on WooCommerce since 2013. I specialize in high-performance web architecture, clean code, and advanced technical solutions. If you’re looking for a reliable software engineer who builds websites that are fast, secure, reliable, and profitable — I am the right fit for your business. I have been in this industry long enough to know what actually breaks a store, and it is almost never what the client thinks it is. I do not just complete isolated tasks; I look at your entire technical setup, detect hidden performance bottlenecks, and deliver clean, scalable code. Prior to commencement, I thoroughly ensure that I can provide optimal solutions, often offering valuable suggestions. I don't just claim quality — I test my work as if lives depended on it. Because here in Ukraine, sometimes they do. My core expertise spans custom WordPress development and deep WooCommerce plugin engineering — from building solutions from scratch to refactoring legacy code. I build lightweight WordPress theme architecture utilizing Gutenberg/ACF development, completely eliminating bloated page builders in favor of clean structure, high maintainability, and real-world performance. Technical Expertise & WordPress Customization Services: Custom WordPress plugin development from scratch (or extending and optimizing existing WordPress plugins). Full WooCommerce solutions: payment/shipping integrations, custom checkout, and deep performance optimization. API Integrations & Automation: Connecting third-party CRMs, ERPs, inventory syncs, and integrating modern AI tools (OpenAI/Anthropic APIs) into WordPress workflows. Custom WordPress themes & WooCommerce themes — clean, lightweight, minimal and optimized for speed and conversions. High-contrast, accessible interfaces — designed to remain usable in twilight, bright sunlight, or poor network conditions. Ambidextrous layouts — checkout, search, and registration flows that can be completed with one hand, left or right. Performance-focused front-end — CSS/JS reduced to the absolute minimum, optimized for PageSpeed Insights, Core Web Vitals, and real-world conditions (poor internet, mobile devices). Problems I Solve: - Complex WooCommerce requirements that no standard WordPress plugin can handle; - WordPress breaking after updates or throwing fatal errors; - Data not syncing correctly between platforms or APIs; - Repetitive manual tasks that should have been automated months ago; - AI tools sitting unused because they are not connected to anything real; - Low search rankings and high bounce rates caused by a complete lack of technical performance optimization; Still here? Let’s continue! 👇 Since 2022, Ukrainian developers have shown the world what innovation under pressure really means. For us, usability and speed were not just “nice-to-have” — they were survival. That’s what I call “combat programming” — development shaped by real survival challenges, not just theory. My principles, born out of extreme conditions: 1. Speed. In Ukraine, power and internet are unstable. I obsessively measure page generation time — my benchmark is 0.1–0.2 seconds. Anything slower is rewritten. 2. Accessibility. In stressful conditions, a website must work anywhere: in twilight, in bright sunlight, with poor internet. Google only started to down-rank low-accessibility sites in 2024. I’ve built accessible websites since 2022, because for us it literally meant saving lives. 3. Ambidextrous Interfaces. Just like a soldier must be able to use a weapon with either hand, your visitor must be able to complete key actions (checkout, search, registration) with one hand. Since 2022, I’ve built such mobile interfaces. Later, studies in 2025 showed: e-commerce stores with one-hand-friendly UX make 12–15% more sales. 4. Security. I filter every input, sanitize every source, and approach WordPress development with security-first principles. Constant cyberattacks made me a "security paranoiac" — your site is protected against SQLi, XSS, and exploits at the code level. 5. Code Quality & Standards. No hardcoding, no nested loops, no deprecated functions. I don’t just claim quality — I prove it. My free plugins are on the official WordPress repository for anyone to review. Check your error.log before and after my work — you’ll like the result. Ready to build your project with speed, security, and resilience? Let’s get started. I work with entrepreneurs and store owners who need a reliable в after being let down by previous developers. Click the "Invite to Job" button or send me a direct message describing what is broken or what you need built. I am happy to hop on a short chat to discuss how we can improve conversions and execute advanced performance optimization on your website. And I will tell you honestly what it will take and when I can start.
