Dear Sir/Madam, glad to represent myself! I am a professional Perl programmer with over 20 yrs expertise. The DB used in most of my projects is PostgreSQL, which I work with since 2015 on high-load systems. Last 9 years I had a number of jobs as an architect on full-stack projects based on Perl and sometimes PHP. My strong OOP expertise in Perl covers more than 8 years, using so vanilla Perl as Moose. I am passionate about Perl and I hope I will be useful for your project! The main skills I can offer straight away: Perl (for OOP vanilla Perl and/or Moose, Mojolicious), DBI, PostgreSQL, MySQL/MariaDB, SQL, RESTful API, Perl/PL, Regex, Parsing, Bootstrap, JavaScript, jQuery, Memcached, RabbitMQ, Docker, Wordpress, PHP, Python, Django, LaTex, AWS, GIT, NaturalDocs, Sphinx. Recent most interesting projects are available in the portfolio part on this page for you. I hope to be useful for your project!

Unavailable, busy working on the ongoing project, unable to take on new work, but open to discuss something. --- Only if you prefer quality and value proactivity. Willing to take long term projects (3+ months) at lower rate (although this may depend on the project). Looking for long-term part time job during the number of hours per week your business can afford (e.g. 10, 20 or 30 hours/week). Willing to solve urgent tasks submitted in Monday, Asana, Slack (or another PM software) parallelly working on continuous improvements (e.g. security or usability improvements) or new developments for your primary project during remaining number weekly allocated hours. ----------- I am your guarantee of 100%+ completed tasks. I’m expert in Web programming with 30+ years of experience. I always focused on implementing the best engineering practices to optimize and automate processes and increase efficiency. My goal as a programmer — to automate everything as much as possible, implementing intuitive and friendly interfaces and ways of communication between humans and machines. I believe that humans should do only creative work, the routine can be done by programs and robots. I strive to complete everything ever started, not dropping on half way. Autonomous and communicative, always very proactive. Skills: Web application development (both front and back-ends) and System application development for Windows, MacOS, Linux and mobile devices (iOS and Android). Secondary skills: I can do DevOps job, set up CI/CD workflows and automation scripts, create browser extensions, Telegram bots, have some design skills with Adobe Illustrator and AfterEffects. Programming Languages: JavaScript/TypeScript (React/Redux, Node.js+Express.js), GoLang, PHP, Perl. Native system app programming in Delphi and C++ Builder. Some experience with Java, C/C++, C#, Vue.js. And of course, HTML/XML, CSS (Sass, Scss, fav CSS framework is Bootstrap, fav components library is MUI). Databases: MySQL/MariaDB, PostgreSQL, MS SQL, SQLite, MongoDB, Interbase HTTP servers: Nginx, Apache, ISS. Cloud Platforms: AWS, GCP (certified in 2018), Azure, Digital Ocean. CMS, CRM, APIs and integrations: WordPress/WooCommerce, ShopSite, SnipCart, SimpleTix (tickets), GIS / mapping (MapBox, Leaflet.js, OpenLayers), marketing CRMs (HubSpot, Zoho, Klaviyo), Twilio, BigMailer, Meta/Facebook, Bing, full set of Google APIs (incl. Google Analytics), Mixpanel, DocuSign, UPS API, Stripe, PayFlow etc. Security: PCI DSS, HIPAA, GDPR compliance. Git & workflows: GitHub, GitLab, BitBucket, Beanstalk. I prefer working with Cloud services (the most experience with AWS and GCP, some with Azure). For CI/CD workflows I prefer Azure DevOps, although I also have experience with GitLab and GitHub+Netlify. Also, although I’m focusing on software development, I have good design skills, can create user interfaces from scratch and draw vector graphic in Adobe Illustrator, etc. And if you need an old school developer, I do low-level Windows/DOS programming in Assembly language too. And can support and update legacy web-applications written in Perl. I am the author of AppControls and DiskControls packs, 2 popular sets of the VCL components for Delphi and C++ Builder (google for AppControls). Significant periods in my career: 2019 — 2024: freelancer + support, maintenance & couching for past projects (after moving to the USA in 2019) 2007 — 2018: Full Stack Web Architect + Team Leader. Founder and CEO in a small B2B-opriented business operating at the intersection of IT and brand marketing. Public opinion research with gamification. 500+ clients including Microsoft, Samsung, Asus, Mazda, P&G, J&J, Amway, Bayer etc. 1999 — 2007: Windows and Web programmer (Delphi, C++ Builder + various SQL databases + some backend web development in Perl and PHP). Remote work on US companies TeknoSurf. Advertising.com (acquired by AOL) and others. 1995 — 1999: Windows programmer for INET LLC (Kyiv, Ukraine). Energy saving and energy metering systems, development of automated workstation for energy dispatcher. 1992 — 1995: DOS programmer (Turbo Pascal and Assembly language), student’s part-time job.

I am an experienced freelance software developer with over 15 years of experience. To adapt to the rapidly changing tech landscape, I have evolved my workflow to combine my deep background in manual coding with integrated AI tools. This hybrid approach, driven by continuous self-development and personal AI projects, allows me to deliver highly efficient, robust, and productive code much faster than traditional development methods. Although my availability is extremely limited, I am actively taking on select new projects - particularly those with a strong AI development focus or highly complex data extraction requirements. My core expertise remains in automated web scraping of extremely hard-to-get data. I write custom Python code to extract information from unstructured sites, large-scale platforms, and targets using heavy 'scraping protection' (like CAPTCHAs, Distil, and obfuscated protocols). Simply put: I scrape the sites that no one else can. I work most effectively given well-defined specifications, including target URLs, keywords, preferred output formats (usually CSV or SQL), and update frequencies. My source code is built for longevity and reliability. I strictly follow Agile and TDD software design techniques, utilizing Git, Selenium, and various APIs to maximize productivity. Beyond modern web scraping, my technical background includes machine learning and statistical analysis (using R, C++, and Matlab), database management (SQL, MongoDB), and Linux administration. I also have legacy experience with Perl. I have a strong track record of delivering multi-threaded applications, notification systems, and complex API integrations (Dropbox, Twitter, Twilio, Sendgrid). If you have a challenging project and well-defined requirements, please get in touch to discuss. Thanks!
