Need workflows automated, a CRM built end to end, or data scraped, cleaned, and delivered exactly the way you want it? You're in the right place. I've been in the freelancing space for over 5 years — no exaggeration. I started building Discord bots in Scratch, and I've spent the years since going deep into workflow automation, CRM systems, web security, and scraping, delivering real projects for real clients. Everything below is exactly what I do — no filler, no buzzwords, every line means something. I'm not a one-trick freelancer. I work across the full lifecycle of data and automation: building systems that run on their own, getting the data that feeds them, and making that data genuinely useful. That range is the point — you get one person who can see a project end to end instead of stitching together three. Workflow Automation & CRM Systems: I connect the pieces so your processes run without manual work. I build automations in n8n — multi-step workflows, API integrations, scheduled pipelines, and data routing between apps — and I design and build inside GoHighLevel: pipelines, custom fields, tagging, intake forms, and task/notification automations. Whether it's feeding data into a CRM, triggering actions on a schedule, or building a full opportunity-tracking system from scratch, I wire it together cleanly and document it so your team can actually use it. Scraping & Browser Automation: I build reliable scrapers and browser automation in Python (Playwright, Selenium, BeautifulSoup) and Golang (bogdanfin TLS for high-security targets, with or without solvers). I handle dynamic JavaScript-rendered sites, login-protected pages, pagination, proxy rotation, session management, and anti-bot defenses — and I download images and documents alongside the data when you need them. Data Processing & Delivery: Raw data is rarely usable as-is, so I don't stop at extraction. I clean it (deduplication, normalization, validation), transform and reshape it, merge and cross-reference datasets, enrich it where useful, and structure messy or inconsistent sources into clean, predictable output. You get exactly the schema and format you asked for — CSV, Excel, or JSON — ready to drop straight into your workflow or CRM. What I specialize in: n8n workflow automation & app integrations GoHighLevel CRM builds (pipelines, custom fields, forms, automations) Scheduled data-collection and processing pipelines API analysis and integration E-commerce product scraping Business directory & lead-generation data collection Login-protected and high-security sites Large-scale and multi-threaded high-performance scraping Data cleaning, transformation, and structuring Tools I work with: n8n · GoHighLevel · Python & Golang · Playwright, Selenium, BeautifulSoup · decent C & C++ · proxy integration & session management · pagination & image downloading · API integration · CSV / Excel / JSON exports · HTML & CSS What you receive: High personalization — I listen closely and keep communication clear and unambiguous. Clean, maintainable code — proper comments, logical flow, and functions structured so the next developer can pick it up effortlessly. Fast, reliable delivery — I take deadlines seriously. Well-structured output — formatted precisely the way you want it. Full documentation & support — video guides, Zoom, AnyDesk, whatever makes you comfortable. I bring capability across multiple fields, and I've kept this focused on where that range delivers the most value. If you need a CRM or automation system built, data collected and cleaned, or the whole pipeline connected end to end — let's talk about your project.
