Oleksandr delivered exceptional automation engineering, seamlessly integrating a robust Python+Selenium workflow with our multi-session Safari automation and persistent cookie-based sessions for a seamless user experience. The clear backend architecture separated responsibilities, resulting in a stable, scalable, and production-ready automation layer. Oleksandr’s professionalism, attention to detail, and reliability make him an invaluable collaborator

Oleksandr delivered outstanding automation engineering from start to finish. He built a robust Python + Selenium system fully tailored to our workflow, integrating multi-session Safari automation, browser profiles, and persistent cookie-based sessions. He also implemented a clean backend architecture with detailed logging, status tracking, and reliable session management, making the automation layer both scalable and production-ready

He built a robust Python + Selenium system fully tailored to our workflow, integrating multi-session Safari automation, browser profiles, and persistent cookie-based sessions. He also implemented a clean backend architecture with detailed logging, status tracking, and a reliable scheduling flow for our posting tasks. Communication was fast, structured, and highly professional — every update was clear, and each milestone was delivered on time. The final solution is production-ready, stable, and easy to extend. If you need reliable, scalable automation or a custom bot for a complex platform — Oleksandr is absolutely the right engineer to hire. Highly recommended.

We needed to extend our existing JavaScript-based SaaS platform with a robust automation layer using Python and Selenium. Oleksandr designed and implemented a scalable architecture that integrates multiple parallel Safari sessions via macOS system users. He reworked our backend logic, introduced a persistent session mechanism, and created a clean database schema for tracking automation statuses and daily post limits. Everything was clearly documented and ready for production. This is exactly the kind of deep system-level engineering we needed — reliable, scalable, and fast to implement.

Working with Oleksandr was an excellent experience. He quickly understood our technical requirements and provided clear solutions for both backend (NestJS/Python) and frontend (Vue + Tailwind). His proactive communication and attention to scalability made the whole process smooth. Highly recommended for anyone building SaaS or automation systems.

You will get JS application for CRUD Operation with Vue.js Composite API, Vue Router
Oleksandr delivered a clean, API-driven Vue 3 application with a strong engineering focus. The frontend was built using the Composition API and Vue Router, strictly aligned with the provided API endpoints.He implemented a scalable CRUD architecture with proper routing, state handling, and validation, and also delivered reusable components for fast CSV upload and bulk data ingestion. The work was purely technical infrastructure, API integration, and maintainable frontend architecture.

Job Success
Kiev, Ukraine - 12:31 am local time
Some examples:
• Python + Selenium multi-session browser automation
• Node.js + Puppeteer scraping + PDF workflows
• n8n automation pipelines
• CRM integrations and API orchestration
• Laravel/Vue business platforms
• WordPress/WooCommerce debugging & stabilization
• AI-assisted backend workflows
Recently I crossed:
→ $50K+ earnings on Upwork
→ 100% Job Success
→ 1000+ production hours
But the most important thing is not the number.
It’s understanding how real production systems fail:
• unstable APIs
• broken automations
• duplicate processing
• scaling bottlenecks
• messy integrations
• legacy architecture under load
This is the work I actually enjoy.
Current stack:
Python, Laravel, Node.js, TypeScript, APIs, Selenium, Puppeteer, n8n, Docker, AWS, CRM integrations.
Right now I’m open to:
• backend automation projects
• AI workflow integrations
• CRM/API orchestration
• stabilization of production systems
• SaaS backend architecture
I work best with founders and business owners who already have traction and need systems that actually scale.
