    I am in Web Development since 2015 and have worked with many Frameworks in the backend and frontend. As my first web experience, I have worked as a full-stack developer and DevOps engineer.

As a DevOps Engineer, I developed CI/CDs via Gitlab CI, deployed NodeJS (AWS Beanstalk), Django (AWS Beanstalk), React (AWS Amplify), and NextJS (Lambda Functions) on AWS. I also managed the infrastructure of the whole project via terraform to have a comprehensive insight about the resources and good version control on them. The technologies I used in these projects include, Python/Django, React, Gitlan CI, AWS (Lambda Functions, RDS, AWS Beanstalk, AWS Amplify, Docker, Celery, RabbitMQ).

    If you are looking for an independent and proactive web developer with a wide range of skills, you have come to the right place. I am an information retrieval and ranking specialist, well versed at helping clients index and search their data swiftly and efficiently. I am at my most efficient working with Python frameworks like Flask or Django, Elasticsearch and SQL databases. Beyond that I can help you build full-fledged web applications, websites, APIs or other custom software. I can join your teams to get a new feature up and running quickly. I do site migrations, Linux system administration, maintenance. I am well versed in ETL operations. I can help you with raspberry pi projects, 3D modeling and specialized research tools. I have 5 years of experience with professional freelance web development, 10 editing and creating media & a good track record of working with designers. We've won awards together. Most notably, The Grand Prix at the 5th Brumen Biennal. Since web technologies are in constant motion, I stay familiar with a wide range of tools/frameworks: python (flask, django, fastapi), elasticsearch, sql (postgresql, mysql, sqlite), js/jquery, html/css/scss, vue.js, angular.js, babylon.js, docker, aws, openrefine, processing, wordpress, prestashop, typesense And while technologies come and go and stacks change, the tasks a developer faces remain the same: assess requirements, choose the appropriate design pattern, write clean reusable and debuggable code, write tests, solve problems efficiently, design storage optimally, understand the end-user, communicate patiently and concisely, identify/remove bottlenecks, take ethical/political challenges seriously etc. I can help you with all of those and more. I am generally curious but particularly interested in working on projects which look to address social, organizational, political or artistic issues. Move fast. Don't break things. Open source them. My educational background is in journalism and media studies. I wrote an MA dissertation on the history of dashboards and live data visualization (Goldsmiths College) and a PhD on the political aspects of valuation via metrics (Coventry University).

    I'm a fullstack PHP developer specializing in Laravel/vue.js I'm just starting on Upwork but have about 15 years programming experience, mostly in web development: building e-commerce websites, content management systems, doing all kinds of API integrations, admin panels, membership sites and so on. I have worked on long term projects with pretty complex functionality. An example would be icraftgifts.com which I built from scratch both backend and frontend. I am a senior developer and can handle virtually any task even if never done it before. If you need a website that requires custom programming and existing solutions (like wordpress) are not a good fit. Or when you need some web application built from scratch according to your requirements. Or if you have an existing website or application that needs ongoing development – these are the situations when I can help you a lot. After the job is done you are not left alone as I am interested in long term relationships with my clients and provide support for the code that I developed. In fact I have had clients that worked with me for years. An example would be thegarageinc.com – a web studio based in Bend/Oregon. The first project I did for this client was in 2003 and now as of 2019 there are still several websites that I support for them. So if you are looking for a reliable developer, you have found the right person :) If you contact me right now, I would be happy to discuss your project with you. I'm located in Europe and available online every day during normal office work hours (between 7am – 4pm UTC). Or I can get online at any other time if we schedule a meeting. Looking forward to talk to you soon. Best regards, Viktor
