I design and build robust automation systems and scalable data extraction pipelines. With a background in Systems Engineering, I specialize in delivering structured, high-quality datasets and automation workflows that are reliable, maintainable and production-ready. My expertise includes: • Large-scale web data extraction • Multi-threaded & concurrent processing • Automation bots (Windows & Web) • Data normalization & transformation (ETL) • Database integration (PostgreSQL, MySQL, SQL Server) • API integrations • Advanced Python development I focus on performance, clean architecture and long-term reliability. If you need a scalable and professional solution — not just a script — let’s talk.

My web development process consists of four crucial steps to achieve maximum quality in PHP applications: Consulting, Analysis, Innovation and Scalability. Demonstrated ability to identify and troubleshoot critical issues. Knowledge of emerging technologies and platforms. Excellent communication skills. Quality and client needs are my priorities. Talent, skill and passion... not necessarily in that order but always aligned :) I put your ideas in action.

We are a software development team focused on building custom digital solutions for businesses that need more than just code — they need clear execution, technical depth, and reliable delivery. What started as a solo freelance practice has evolved into a flexible team of specialists. This allows us to adapt to the real needs of each project: when a task is best handled by one expert, we keep the process lean and direct; when a project requires broader coverage, we work as a coordinated team across multiple technologies. Clients work directly with professionals involved in the actual execution of the project. We value clear communication, strong ownership, practical problem-solving, and software that is built to be maintainable, scalable, and useful in the real world. Our team works across a wide range of technologies, including: Python / Django, PHP, JavaScript, MySQL, C# / .NET / .NET Core, WordPress, custom WordPress plugins, Svelte, Angular, Flutter, HTML5, Stripe, Google Maps API, GPS, Cartography & Maps, and n8n automation. We help businesses with: • Custom web application development • Backend systems and API development • Frontend implementation with modern frameworks • Mobile and cross-platform app development • WordPress custom development and plugin creation • Payment gateway integrations • GIS, mapping, and geolocation-based platforms • Workflow automation, integrations, and process optimization with n8n • Technical planning, architecture, and scalable product development Our structure is flexible by design. Some projects only need one highly specialized developer. Others benefit from a broader team working together across backend, frontend, mobile, integrations, automation, and deployment. We can do both efficiently. We are not focused on delivering generic solutions. We build software tailored to the goals, constraints, and growth plans of each client. Whether the need is a custom platform, a business-critical integration, an internal tool, a mobile app, or a complete product from scratch, we aim to deliver solutions that create real value. Our track record here reflects the seriousness, consistency, and quality we bring to every project. Let’s build something solid, scalable, and valuable together.

"If human thinking fails, try anthropoid thinking. Fresh approach helps remove the obstacle." There used to be an ape-man in the photo: MoonWatcher. His bio takes us way back in time. I like to think of MoonWatcher as my oldest known ancestor. Had he lived in our times, he'd be well versed in the following: ● Database systems: • Airtable: database design, automation and scripting. • MS-Access, a sentimental favorite, handy and versatile like the ancient bone-made tools. • other databases: MS-SQLserver • MySQL • PL/SQL • DB2 SQL/400. • lastly a set of forgotten, prehistoric tools: dBase, Borland, Paradox, FoxPro. ● Programming languages (in alphabetical order): • C# • Cobol, all its reincarnations • IBM AS/400-iSeries, its languages: RPG, Cobol, CL, SQL/400, Query/400. • Javascript • SAP Datasphere, SAP Analytics Cloud • Visual Basic, all its reincarnations As you've read up to this point, you may feel intrigued by MoonWatcher's origins and developments. Read the first chapters in Arthur Clarke's "2001, A Space Odyssey". The anthropoid's fears and amazements, his early attempts at understanding the world, are magistrally depicted.
