Senior Scripter
Verve
developing survey web pages, doing data analysis and working on automation apps. I created a QA app which 'scored' survey scripting correctness, and a survey creation automation app which took a project defined by the project owner, converted it to XML and JSON, and then automatically created the whole project in the two internal scripting apps, saving up to 80% of scripting time and only letting the human do the most difficult retouches. Word documents which were completely different from one another were converted to HTML and then to clean data, and that dataset was used to create 'features' like in a machine learning algorithm.

Summary
I am a results-oriented AI engineer, interested in emerging technologies and working with data. I am also a certified trainer in web technologies, having mentored entire teams in two different companies so far.
After starting out as a survey programmer and getting a hand for statistical analysis and market research, I have been a web developer since 2015 - when I started creating web apps and UI components. My work ethic has led me to winning two Employee of the Year awards and I was also an Innovation Prize winner for my additions to the company tools.
In 2018, I worked on a large-scale React project for an enterprise in New York City. As a developer and consultant, I implemented new features, components, workflows, and created middleware code. I also re-architected legacy code while learning a lot of useful processes for large-scale development and deployment.
At the end of 2019 I switched to applying my skills in the online store realm, managing a multi-site online store (PHP + MySQL) and creating new modules, researching how best to apply new technologies in order to solve emerging issues.
From 2023 I've been active in a market research company where I've been using my web development (and AI) skills to automate processes, analyze data and help my colleagues on various development tasks.
Finally, in 2025 I combined my programming and data analysis skills, together with my greatest asset - my creativity - to produce data-focused solutions in the AI realm, as well as researching innovative ways to solve complex issues in the B2B sales domain.
