🔹 Core Expertise Backend development: Java, Spring Boot, Gradle, microservices architecture, modular systems Data scraping & aggregation: Large-scale parsers for real estate platforms, marketplaces, and betting websites. Features: anti-bot protection bypass, proxy rotation, request throttling, task scheduling, data deduplication Databases: PostgreSQL (schema design, indexing, performance optimization, migrations with Liquibase) Message brokers: RabbitMQ – async pipelines, distributed parsing tasks, decoupled microservices DevOps & infrastructure: Docker, Docker Compose, Traefik (reverse proxy, HTTPS, domain routing), Hetzner bare metal deployment, monitoring with Prometheus & Grafana APIs & integrations: RESTful APIs, authentication (JWT), API gateway, rate-limiting & security layers Automation bots: Telegram bots integrated with backend systems (real-time notifications, subscription-based services, custom filters) System monitoring & analytics: ELK stack, Grafana dashboards, Prometheus metrics, Node Exporter 🔹 Example Projects ✔ Real estate data platform – Developed an industrial parser for real estate websites (OLX, Dom.ria, Lun.ua). Features included real-time data extraction, proxy handling, Telegram notifications, and scalable architecture to handle thousands of listings daily. Delivered value to real estate agencies by providing clean, structured, and up-to-date property data. ✔ Marketplace scraper – Built a modular parser for marketplaces (Rozetka, Prom.ua) with configurable product categories, automatic error recovery, and data export via API. Designed system so that adding new marketplaces requires minimal code changes. ✔ Sports betting pre-match parser – Implemented an asynchronous Java parser for Leonbets (without browser emulators), handling parallel requests with strict resource limits. Achieved fast response times while avoiding detection and blocking. ✔ Automation & notifications – Created a Telegram bot for real-time client alerts. Example: users get instant updates when new real estate listings match their saved filters (location, price, number of rooms). This system is monetizable through subscription or API access. ✔ DevOps & infrastructure – Set up full-stack infrastructure for a parsing platform on a dedicated Hetzner bare metal server: Docker-based deployment, Traefik with Let’s Encrypt SSL, isolated users for services, Postgres database cluster, ELK for logs, Prometheus & Grafana for monitoring. 🔹 Why Clients Choose Me Scalable, not one-time scripts: I build systems that can run for years, not fragile scripts that break after a minor website change. Business-first approach: I don’t just write code — I create solutions that solve real business problems, generate revenue, and save costs. Reliability: My systems are modular, maintainable, and easy to extend as the client’s business grows. Clear communication: I provide updates, documentation, and practical advice to ensure clients understand the solution, not just receive a “black box.” End-to-end delivery: From parsing logic to backend APIs, deployment, monitoring, and automation — I can cover the entire lifecycle of the project. 🔹 What I Can Build For You Industrial-grade web scraping platforms (real estate, marketplaces, betting, custom domains) Backend microservices for data processing, APIs, and client access Automation pipelines with RabbitMQ for async processing API-first products that clients can resell or integrate into their systems Real-time notification systems (Telegram bots, dashboards, webhooks) Secure deployments with monitoring, logging, and disaster recovery 🔹 Technologies I Use Languages & frameworks: Java, Spring Boot, Gradle Databases: PostgreSQL, Liquibase Messaging: RabbitMQ Infrastructure & deployment: Docker, Traefik, Hetzner servers, Linux Monitoring & logging: Prometheus, Grafana, ELK stack Integrations: REST APIs, Telegram bots, payment systems (for monetization) 🔹 My Approach When I join a project, I don’t just deliver code — I analyze your business case, design the most efficient architecture, and implement a solution that scales with your needs. I focus on automation, cost optimization, and maintainability, so you can grow your business without constantly worrying about technical issues. I specialize in turning raw data into valuable, structured, and actionable information. Whether you need to automate data collection, integrate multiple platforms, or launch a SaaS-style data product, I can deliver a solution that works long-term. ✅ If you are looking for a developer who can build not just scripts but scalable, production-ready systems that deliver real business value — let’s work together.

I am a Software Quality Assurance Engineer with hands-on experience testing web-based and data-driven applications in real project environments. My focus is on identifying functional, usability, and integration issues early so products can be released with confidence. I primarily work on manual testing, including functional, regression, smoke, sanity, and end-to-end testing. I write clear and structured test cases, execute test cycles thoroughly, and document bugs with proper reproduction steps and evidence using standard bug-tracking tools. I also perform API testing using Postman and basic database validation using SQL to ensure backend data accuracy and system reliability. In addition to manual QA, I have practical experience with Selenium-based automation using Python and Java. While manual testing is my core strength, my automation background allows me to support regression testing and contribute to automation efforts when needed. I value clear communication, attention to detail, and structured testing practices. I work comfortably in Agile environments and aim to provide clients with actionable QA feedback, reliable reporting, and long-term testing support. 📩 If you’re looking for a QA engineer who can handle day-to-day testing and also support automation as your product grows, I’d be glad to discuss your requirements.
