Hubspot API Expert Dev It was great working with Jan although I had requirements that kept changing and my original brief was a bit vague. Thank you.

Build a Rails service object to connect our meeting scheduling system to Microsoft teams / Graph API We first asked Jan to help with a relatively contained coding issue, but over the months he worked with us, he ended up assisting us on a far broader range of issues. He's very capable, good at explaining the best way to proceed and has been hugely helpful in keeping our Rails system working. Highly recommended.

"connectwise manage API" specialist. We worked with Jan for almost a couple years on a project. Lots of changes being made along the way. He brought lots of talent to the table, and not sure this project could of been completed without that knowledge.

Maintenance and new feature building of Healthtech Ruby on Rails app Jan has worked with us now for a while on a number of different projects. He is a super hard working developer that gets almost anything you throw at home done quickly and at a high standard. I highly recommend him for any full stack projects, especially Ruby on Rails with React.

Backend Code Review Jan was as professional and meticulous as he's always been in our prior interactions with him.

We asked him to do a code review of our Ruby on Rails codebase, and he did a terrific job with his many recommendations.

I am the go to guy resolving any tech problems in your company. Value is what I am focusing on. I am mostly experienced with Ruby on Rails and React so probably a full-stack engineer title sticks for me, but I am not only focusing on the programming work. My goal is to understand your business and its problems helping you operate more smoothly, worrying less about development. Delegate any challenge to me, I will find the solution to it allowing you to focus on your things.

As mentioned I am seasoned full-stack dev, mostly experienced with Ruby on Rails(also being it's open-source contributor) and React. But during over 6 years been working on vast majority of projects in many different programming languages and on different positions. I am not scared of building web scrapers, reporting tools or managing servers(DevOps). Being an all-rounder helps me understand the businesses on multiple levels and have a broad perspective which results in the happiness of my freelancing clients.

Project Highlights:

🔹 COVID-19 Vaccination Passport Platform: I architected a system from scratch for a major German city, efficiently managing over 500,000 records, ensuring security, and maintaining high scalability during peak demands.

🔹 Telehealth Platform for Physiotherapists: I spearheaded a redesign of search functionalities, achieving a tenfold improvement in performance and markedly enhancing the user experience.

🔹 Marketing Automation Platform: My implementation of AI-driven messaging and data enrichment strategies has saved hundreds of hours and notably increased conversion rates.

Client-Centric Approach:

🌟 Problem Solving: I dive deep into each project's unique challenges, ensuring solutions are tailor-made to address specific needs.
🌟 Value Delivery: Each solution is designed to maximize ROI, whether through enhanced efficiency, increased security, or scalable growth.
🌟 Technology Expertise: As an official Ruby on Rails contributor, I bring authoritative knowledge and innovative practices to every project.

Technical Skills:
🛠 Languages: Ruby, JavaScript, SQL, Elixir, Python, HTML/CSS
🛠 Frameworks/Tools: Ruby on Rails, React, Docker, GitHub Actions, RSpec
🛠 Databases: PostgreSQL, MariaDB, Redis, AirTable
