    Solutions Architect With a decade of experience, I am an automation expert and provide strategy consulting for data analysis and report generation. As a Data Engineer, my background includes data governance, data quality, data architecture, Azure, AWS, UiPath, algorithm development, ETL/ELT, API development, Tableau/Pentaho, and web app development. My projects have solved interface and efficiency issues through contract work for companies like Merrill Lynch, ContractRx, and the City of Baltimore. I have additionally worked for "smaller" companies in the Healthcare space. My clients are executives and business owners who work with large or sensitive data sets. Some are unaware of the capabilities of technology and the large amount of work time saved through data automation. With my assistance, our clients can streamline their business intelligence pipelines - often cutting costs and saving thousands of work hours per year. The most commonly requested projects typically include: - Executive dashboard creation and automatic report generation - ETL design and process automation - Generating new data or or external files based off input data - Cloud migration, database modeling and design, improving data pipelines - Enterprise app development and internal web tools - Creating aggregate data feeds for tools like Tableau/PowerBI/Pentaho - Data Integration (APIs, AWS pipeline) Languages --------------------------------------------------------------------------------------- SQL, Java, PLSQL, VB, Perl, Python, ASP, .NET, BASIC, C++, PHP, Ruby on Rails, JavaScript, HTML, XML, jQuery Databases --------------------------------------------------------------------------------------- Oracle, SQL Server, PostgreSQL, MySQL, DB2, and Access If you have a larger or more complex project in mind, my team of skilled developers will provide you with a solution at a blended rate. If interested, please ask for details. I offer discounts for repeat clients or larger projects (500+ hours). Feel free to contact me if you have any questions - you can typically expect a reply within a day. Thanks for reading

    I have wide experience in developing, designing and managing projects with a variety of technologies. My preferred development languages are Perl, Go and Python; also, I'm proficient in Java, Javascript/AJAX, jQuery, full-stack web development and SQL. Ones of the most effective my skill are: automating of routine tasks; creating some scripts and utilities; creating desktop application; boundary problems: cross-technology, cross-language, reverse engineering, etc. I met with the computer for more than 20 years ago and since then my work is closely related to programming. Most of this time I was working alone, so I implemented the full cycle of software development in the projects I've worked on. I am a fast learner and problem solving oriented programmer. My priorities are quality and client satisfaction.

    My primary skill is web and desktop automation. Over the last 15 years, I have developed a wide range of applications using Python, PHP, C#, Google Apps Script, different APIs, frameworks, Zapier, Make etc. Most of my work is done using Python but I can work with Perl, C#, PHP, VBA, VB.NET too. Also I have worked a lot with Zapier and some of my workflows / zaps are really complex: including dozens of steps and different APIs / app. I have created several hundreds of web scrapers, spiders and different parsers (CSV, XML, XSLT, JSON, text logs etc). I can work with different database engines (MySQL, Postgres, MS SQL Server etc) and other output formats (CSV, Excel, XML, JSON). Usually my work starts with a simple (and free) demo version which my client can evaluate. My rates are not the cheapest but my code is really good and I'm always prioritize code quality over cost, resulting in robust and maintainable solutions.

    Ever since I was a kid, I've been fascinated by computers. I was introduced to Linux almost 15 years ago, and that was the time I discovered my first true passion.. I worked as a software developer (iOS - Swift) and Linux system administrator, but I wasn't satisfied with neither developing corporate/commercial applications, nor repeating same routines like adding/removing users, setting up VPSs, configuring programs following the same conventions.. I needed something to satisfy my passion for creativity and problem solving/algorithmic/programmatic thinking, but that is still related to Linux.. Enter Bash, an amazing way to interact and utilize full potential of your Unix OS in a totally programmatic manner.. I've been perfecting my Bash skills for over 5 years now, and I have quite a lot of complex projects, successful jobs and happy clients to support that.. I'm also quite proficient with Python as well, but given my stand on mainstream appliances, I'm only interested in jobs utilizing core principles, I DON'T have any "domain-specific" skills, so please DON'T contact me about AI/Machine Learning/Trading/Full stack/bot automation etc, only basic python skills.. That being said, if you're looking for a Linux expert who thinks of Bash as a programming language and vim as an IDE, feel free to reach out and I'd be happy to provide my services! :)

    Overall I am in IT industry business from about 1999. The first years I've mostly been working with servers and networks, later about in 2003 I've got interested in programming. Worked with Perl/CGI,ASP, but mostly with PHP/MySQL. I am in IT business untill nowadays. I think there is no need to mention that I worked with SOAP, OOP, XML, various API, REST etc. I still enjoy Classis ASP, old-code software like OsCommerce etc. I have a commercial experience in XHTML/CSS, frameworks etc. My favourite framework is CodeIgniter. To "keep a PHP shape" I also like creating of pure structural code on my own projects :) So I can fix 99.9% of the software/server problems, as I am a programmer with strong system administration background. ******************************************************************************************** 1.I am not one of those who wins the bid and then seeks for other programmer to complete a task; 2.I am not one of those who shouting "I am the best and the cheapest". The best cannot be the cheapest, right? (maybe only when there ar no reviews). You cannot buy Maybach for 100$, right? I think every webmaster should expect the same quality of work he pays :D 3. I want you to make happy with my work, so i will work untill you are satisfied. 4. I always try to place reasonable and wise-priced bids. I cannot place 100$ bid for 2 lines of code. But if you want "create flash casino connected with db and all featured edited within admin area+ affiliate system" for 20$... I think you will just get a stolen software, wich copyright links removed. I saw such things many times. Believe me, you will mee problems later with that :D But of course, it is your choide. 5. I usually need FTP/Cpanel access, to modify your files. If you cannot provide this login dues some reasons, please DO NOT accept my bid. How can I work, then? I CAN make some exceptions, of course. 6. If I bid, I am 99% sure about success. 7. I always provide support for my jobs. 8. If I do not respond email within 1 day, that means I am busy like in hell, so I am just sorry about that. Just write to me AGAIN, please. You WILL get a response. Sometimes I miss emails via lots of emails in my inbox. 9. I ususally do not bid, if webmaster wants: "Just change one colour", including reinstalling server, reslicing entire website, fix bugs :D In those cases I just bid for "Just change colours"; well, usually I do not bid. Also, if you have lots of cancelled projects, I do not trust such webmasters too much. Well, I can work for those webmasters, but require escrow. 10. usually I do not require escrow. I try make webmaster happy first, in order me to keep for further jobs. 11. I am always open for any negotiations :D 12. If I've made fixes for 15$, that does not mean I will work with your complex project for that price. As I've mentioned, prices should be adequate. Quality of work usually is proportional of the price + programmer reviews. 13. You can just contact me for some consulting or questions. That does not mean I will work offsite. 14. I read all invites to bid. If I do not bid or respond, that means your budget is far away from realistic budget. Believe me, I also would like to hire people to work for $1 or less per hour. I dont believe, you can get a quality work for that price. 15. Please DO NOT BOTHER me with $5 projects. I will also ignore "a very simple job, I simply dont know how to do it". To become a millionaire is also a very simple jo, I simply dont know how to do it. I will also ignore "the cheapest wins". Even I am new on this site, I am active freelancer on some other sites. I think I could give links to my profiles on those things. Also... I did not used any spell checker or Google translator to write all this, so you can evaluate my English level :D Thanks for reading. :D

Perl FAQs

What is Perl?

With the slogan, “There’s more than one way to do it,” Perl came on the scene as a flexible, powerful server-side language that could do more than one job. And for a number of years, Perl made very important contributions to modern web technology—especially for a language that was developed before the web even came to be.

It’s prominent on the list of back-end programming languages, has an active developer community, and stands out among other server-side scripts as one of the most popular languages used in CGI scripting. But in terms of developer popularity—arguably one of the key barometers of the health and future of a technology—it’s appeared to wane with new learners, falling behind popular languages like Ruby and Python.

Today, Perl is still really prominent—and often makes up the P of the popular LAMP stack (Linux/Apache/MySQL/Perl, PHP, or Python). Get to know a little more about this language below.

  • Perl is a server-side script. Server-side scripts create the architecture and functionality of a site that you don’t see to help the client-facing part of a website you do see run smoothly and dynamically.
  • Perl is free, open-source, and object-oriented.
  • It’s cross-platform and lightning fast. It was built to run on the Unix operating system but can run on over 100 platforms. And compared with other scripting languages like Python and Ruby, it runs incredibly fast and performs well handling large amounts of data.
  • It interfaces well with C/C++ languages, with major syntax similarities to C and PHP. Unix has a built-in Perl interpreter.
  • It supports database integration with almost every possible relational and non-relational database, serving as the “glue” for back-end software. It’s ideal for database mining, as well.

Perl is most often used for:

  • System administration
  • CGI scripting
  • Intrawebs and older web systems
  • Data mining and statistical analysis
  • GUI programming
  • Web automation
  • Security system prototyping
  • Network prototyping
  • Regular expressions in bioinformatics, widely used in the 1990s
