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.

Are you looking for a skilled Prompt Engineer to help you automate your customer support, streamline your workflows, or improve your user engagement? Look no further.

I am a seasoned developer with a strong natural language processing and machine learning background. I have worked on several projects that involved building conversational interfaces, chatbots, and virtual assistants for various industries, mostly e-commerce and marketing.

One of my recent projects involved developing a virtual assistant for a marketing agenc that helps them sell their services. Using a combination of prompt engineering and Chat GPT API integration we've built a conversational interface that could understand the user's needs, track the conversion steps, and provide personalized recommendations based on their sentiment.

In addition to my expertise in prompt engineering, I am proficient in several programming languages, I do have over 5 years of experience in Ruby programming, with contributions to Rails framework. Additionally I am no stranger to JavaScript and it's libraries like React.

If you're looking for a skilled Prompt Engineer who can help you leverage the power of conversational interfaces and NLP to improve your business processes and user experience, let's chat.
