Hire the Best Regular Expressions Developers in Bucharest, RO

I build reliable automation, scraping, API, and back-end solutions for clients who need more than a basic script. My strongest work is in Python, Playwright, JavaScript/Node.js, Express.js, REST APIs, web data pipelines, and automation systems that need to survive real-world edge cases: dynamic websites, login flows, rate limits, unstable third-party services, Cloudflare-like restrictions, proxies, browser automation issues, and messy deployment environments. I can help you with: - Web scraping and data extraction from dynamic or login-protected websites - Playwright/Selenium automation and browser workflow automation - Custom APIs and back-end services using Node.js, Express.js, Python, and REST APIs - Reverse analysis of request/response flows to understand hidden or undocumented APIs - Data cleaning, XLSX/CSV/JSON exports, Airtable/API integrations, and recurring data pipelines - OpenAI API / Assistants API integrations for automation workflows - Debugging broken automations, scrapers, PHP sites, redirects, hosting issues, and deployment problems - .NET/C# desktop or web application support when needed A few examples of work I've delivered: - Built production-ready Node.js/Express APIs by analyzing third-party request flows and internal API behavior - Extracted 21,000+ product records from login-protected wholesale websites and delivered clean XLSX datasets - Built and maintained recurring product refresh pipelines for European e-commerce wholesalers - Rebuilt unstable Selenium scrapers into faster Playwright/aiohttp-based systems - Integrated OpenAI Assistants API into automation bots for contextual conversations and long-running sessions - Fixed broken PHP/hosting/Cloudflare/SSL redirect setups and restored unusable websites - Built C#/.NET desktop tools, ASP.NET MVC apps, REST API integrations, and automation utilities I focus on practical delivery: understanding the workflow, finding the reliable technical path, building the solution, and making sure it can run repeatedly without constant supervision. If your project involves scraping, automation, APIs, browser automation, data extraction, or a technical problem that other developers could not solve cleanly, I can likely help.

Well, I'm Sorin and for over 15 years, I've been doing various programs, scripts and useful things. Lately, I grew very fond of Investment Dominator and their "Format mailing list". Not limited to this, I think that whatever makes sense or has a logic, I can transform it into a small application or script. If we're talking about tabular data, that's even better. I don't really care how big the data is, I think I can handle it. For 12 years, I worked for a courier firm, so my skills increased with Excel, ETL, data handling. For the last 6 years, I'm an Application Admin for a bank and I developed or leveled up different skills: scripting, automation, monitoring, permissions, databases, SSL certificates. I try to think of myself as being very honest so, if I present you with a solution, then that solution I would've use it if I were in your case. If you got this far and you think that I might be able to help you, feel free to start a conversation and let's see if this is the case. Thank you
