"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.

VB.NET and VB6 with Access development (archived) $$

Carlos was a lifesaver on our VB6 migration project. Legacy migrations are rarely easy, but he showed a deep understanding of both the old VB6 logic and the modern VB.NET we moved to. He didn't just convert code; he refactored and optimized it effectively. Communication was clear. Highly recommended for anyone dealing with complex legacy systems. [11 July, 2025] Great SQL query development.

Carlos is quick to respond, very professional and meticulous. This was our second project, and he delivered as he promised. I'll work with him again for sure.

Throughout my career I’ve had few chances (or need) to achieve certifications on any topics. Typically I’d be provided technical manuals and functional documentation to read, grasp and apply to practice on the go. Such an approach, rather imposed by business dynamics than thoughtful maturation, led me to build an eclectic methodology for systems development, which I dubbed “Stick n Bag” in a colorful reference to its expeditious steps.
