Hire the Best Puppet Developers in Kyiv, UA

I build complex automation platforms, data scraping systems, API integrations, and AI-powered solutions that eliminate manual work and turn inefficient processes into scalable, production-ready systems. I enjoy working on projects where the problem is genuinely complex and the solution requires real engineering thinking, not just plugging libraries together. If you need something built properly — designed to scale, reliable in production, and easy to maintain — that's exactly the kind of work I do. ➤ What I can help you with: • Automation systems (Workflow Automation, Browser Automation, AI Automation) I build automation systems that replace manual workflows with reliable, scalable processes. This includes browser automation, multi-step workflow automation with full business logic implementation, and AI-powered automation that makes systems smarter and more adaptive. • Data Scraping systems (Web Scraping, Data Extraction, Real-time Monitoring) I develop data extraction solutions for any complexity — static and dynamic sources, protected targets, and real-time data monitoring. The result is always structured, clean data delivered to any format or destination your project requires. • Backend & SaaS development (API development, API Integration, SaaS Platforms) I design and build backend systems and complete SaaS platforms — from REST API development and third-party integrations to full product architecture. Whether you need a standalone API, a complex integration layer, or an entire platform built from scratch, I handle the full cycle from architecture to deployment. ➤ Why me? My work goes beyond standard implementation. I have a deep understanding of how browsers, security systems, and detection mechanisms work at a low level — which allows me to build automation and scraping solutions that hold up against complex, well-protected targets. What sets my work apart is that understanding: I've built a private human behaviour simulation library from scratch — with a custom algorithm for realistic mouse trajectory generation, keyboard dynamics, and AI-assisted behavioural patterns — which reflects how seriously I approach the engineering behind automation. ➤ Tech stack and tools: Python, JavaScript, TypeScript, Go, FastAPI, Django, PostgreSQL, MySQL, MongoDB, REST APIs, Selenium, Playwright, Puppeteer, Scrapy, BeautifulSoup, Pandas, cloud services, OpenAI API, ChatGPT, Claude, Gemini, Google Sheets API, Airtable API, CRM APIs, payment APIs, and custom backend systems. I work best when the project requires more than execution — when there's a goal to define, a scope to think through, and a solution that needs to hold up long-term. If you need an experienced developer who can understand the goal, clarify the scope, build a reliable solution, and support it over time, I can help. Send me a message with your project details, data sources, tools, API requirements, or current workflow, and I’ll help you define the best technical approach.

I build production-grade Python-based data extraction and Web Scraping systems that survive where others fail. Projects range from focused data extraction tasks to large-scale Anti-Bot resilient infrastructures — each engineered for stability, performance, and long-term reliability. Over 12+ years, I’ve designed extraction systems processing 1B+ structured records across marketplaces, aggregators, AI/ML platforms, competitive intelligence systems, and enterprise catalogs. My systems are built using Python, Scrapy, Playwright, and Selenium — combining Web Scraper development, Data Mining, API Integration, and ETL pipeline design into stable, production-grade architectures. Whether you need a targeted scraping solution or a high-volume distributed pipeline, I architect the right system. When data becomes mission-critical — reliability matters more than code. ────────────── What I Build ────────────── • Custom Python Web Scraper and Data Extraction systems aligned with business logic • Scalable web crawlers handling anything from selective datasets to millions of pages • Continuous update pipelines (batch & incremental ETL workflows) • Queue-based distributed processing • High-concurrency execution models • API-based data extraction and system integrations • Clean ingestion into PostgreSQL / MySQL / APIs / cloud storage • Automated validation, deduplication & anomaly detection • Structured Data Mining pipelines for growing datasets You receive structured, business-ready datasets — not scripts to babysit. ────────────── Anti-Bot & Protection Layers ────────────── Modern platforms are protected.I work inside environments guarded by: - Cloudflare (403 / 429 / Turnstile) - DataDome behavioral detection - Akamai Bot Manager - PerimeterX - Reverse engineering of detection vectors & TLS/JA3 fingerprint alignment - Headless & browser fingerprint detection - hCaptcha / reCAPTCHA v3 Enterprise - Sustainable session & token lifecycle management This is not proxy swapping. This is controlled, sustainable access engineering. ────────────── Scale & Cost Control ────────────── As volume increases, scraping typically fails in two ways: 1) Stability collapses 2) Infrastructure & proxy costs explode I optimize concurrency models, routing logic, batching strategy, request distribution, and traffic patterns to maintain high throughput with controlled infrastructure load. Where relevant, I reduce proxy and infrastructure costs by up to 30% while preserving system stability. Result: High uptime. Predictable performance. Controlled margins. ────────────── Future-Proofing ────────────── Websites evolve. Structures change. Protection layers update. I implement structural drift monitoring and heartbeat systems that detect site changes before pipelines fail — shifting from reactive recovery to proactive control. Most developers fix scraping after it breaks. I design systems that minimize breakage from the start. ────────────── Who This Is For ────────────── • Founders building data-driven products • AI/ML teams requiring proprietary datasets • Businesses automating competitive intelligence or market tracking • Companies where reliable data access supports growth ────────────── Confidence Check ────────────── If needed, I can provide a working sample before full engagement to demonstrate data quality and bypass stability. To get started, send: - Target website(s) - Required data fields - Expected volume - Update frequency - Preferred output format Whether you're starting with a focused scraping task or building a large-scale data infrastructure — let’s build it properly.
