Hire the Best Web Scrapers
in Turkey

I help researchers, data scientists, and AI teams process, clean, and structure complex biological datasets and multimedia inputs into reliable, analysis-ready formats. With a strong academic background in molecular biology, bioinformatics, and music theory, I bridge the gap between computational automation and domain-specific precision. Core Technical Capabilities: • Bioinformatics & Scientific Data: RNA-seq data processing pipelines, differential gene expression analysis, academic literature curation, and scientific data mining (PubMed scrapers). • Data Processing & Scripting: Python (pandas, NumPy, SciPy, Matplotlib), R, and statistical testing (ANOVA, t-test, regression models) built in Linux/WSL environments. • AI & Audio Annotation: Audio metadata labeling, instrument/genre classification, and bilingual (English/Turkish) LLM output evaluation (RLHF). • Automation & ETL: Custom web scraping (Playwright/BeautifulSoup), automated data extraction, and structured dataset formatting (JSON/CSV/SQL). Whether you need a reproducible data processing pipeline, a custom script debugged, or domain-specific dataset annotation, I deliver clean, well-documented, and mathematically sound results. Available for both short-term problem solving and ongoing research workflows. Let's discuss your project.

Your business runs on data — leads, contacts, records — but it's scattered across sites, sheets and tools, and someone on your team is still copying it by hand. I build the automated systems that make that work disappear. ⭐ Top Rated · 100% Job Success · $10K+ Earned · 600+ hours delivered Hi, I'm Caner 👋 My foundation is in mathematics and data science — it's how I first learned to code — and it grew into building production data & automation systems. That's how I work: precise, structured, and built so nothing breaks silently. 🚀 A recent result: I built a custom extraction system that collected and enriched 100,000+ contacts across 19 data fields — 1.9 million data points. By hand, that's over 2 years of full-time work. I engineered the extraction logic for each source and solved the anti-bot challenges directly, using AI agents only where deterministic code fell short (like email discovery) — keeping running costs low. Other work: ✅ Verified B2C lead-list systems (Ontario, Canada) — 5-star rated ✅ An AI Agent web scraper a client called "the most skilled and detailed developer I've worked with" ✅ Currently building an ongoing researcher contact-enrichment pipeline (Python, Supabase, APIs, scraping) The problem I usually solve: Data lives in ten places. Leads slip between channels. Reports are built by hand every week. You know time and money are leaking somewhere — but the current setup makes it hard to see where. I turn that mess into one system that collects, cleans, enriches and moves your data automatically. 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 𝗜 𝗯𝘂𝗶𝗹𝗱: • AI agents & LLM workflows — automations that classify, summarise, enrich and act on your data (Python, OpenAI/Claude APIs) • Automation & ETL pipelines — lead gen → enrichment → CRM/Sheets → outreach (n8n, Python) • Data analysis & dashboards — clean, structure and analyze data into clear insights and live dashboards (Pandas, SQL, PostgreSQL, Supabase), backed by a strong mathematical foundation • Data collection & scraping — when a project needs external data, resilient anti-bot scrapers (Playwright, Selenium) feed clean, verified data straight into the pipeline ⚙️ I build what actually fits — not the flashiest option. Fully "hands-off" data systems only work when the source is fixed and stable. When sources change or block you, it takes real engineering — the right architecture, an anti-bot strategy where needed, and AI used only where it genuinely adds value. Sometimes the right answer is an AI agent; sometimes it's a cleaner pipeline or one source of truth instead of five tools. I'll tell you honestly which one your project needs — and keep your costs down while I'm at it. 🏗️ Built to maintain, not to throw away. Each data source is engineered as a reusable module — not a disposable one-off script. When target sites change their structure (which they do every few months), refreshing the whole system takes days instead of a rebuild from scratch: what would be a 3–4 month rebuild becomes a 1–2 week update. That's what makes it viable for large companies running data operations at scale — no constant babysitting, low long-term maintenance cost. Why clients keep me: ✅ Fault-tolerant by design — no silent failures, no data loss, no schema drift ✅ 0–4 hour response time and clear, honest communication ✅ Delivered exactly what's promised, on time What clients said: "…the most skilled and detailed developer I have worked with." "He goes above and beyond and always delivers!" If your data or lead process is creating manual work or hiding revenue somewhere it shouldn't — send me a message and let's map out the system that fixes it. 🚀

I help businesses collect, clean, and organize data from websites and documents. I work with Python, Requests, BeautifulSoup, Pandas, Excel, and Google Sheets. I can help with web scraping, data entry, web research, lead generation, contact list building, and Excel/CSV data cleaning. I have built sample scraping projects that collect public listing data and organize the results into clean Excel files. I can extract fields such as company names, websites, emails, phone numbers, prices, locations, and source URLs. I focus on accuracy, clean formatting, duplicate removal, and easy-to-review spreadsheets. I am new to Upwork, so I keep my rate affordable while building my first reviews. I can also provide a small sample before starting the full project.
