About
Over 4 years experience
I was developing many various things starting from SDN (software defined network) and ending on regular web applications rich in functionality like digital medical clinics, insurance shop and internal applications. Although I am also into marketing, I can also help you monitor your business conversion and introduce analytics tools, to monitor clients behavior.
Things I can do for you
I specialized in writing custom applications that meet your needs, when generic templates available on the web fail. I can also help speed up your application by scaling it or doing optimization according to web vitals parameters. Last but not least, I can help with moving your company into a cloud provider like Azure, AWS, GCP as a part of scaling your business.
Keeping your business growing
When your business will grow larger you also need to scale your application. I can help you also with that, because I have experience with scaling applications using cloud providers, so your company can provide service for millions of people around the world! I also have knowledge about marketing and SEO, which helps your company reach more and more people

Projects
Digital clinic
Application helps with running the clinic, main functionality was collecting diagnostic and examination from users devices, shared by doctors. It also has the ability to carry out video and text chat with the patient by doctor. Last but not least there was an option to conduct a survey, it was very useful especially during the pandemic period. There were multiple clients who were using the product and they were really satisfied with it. I was also responsible for a maintenance of the application, to solve bugs reported by user and add new functionalities according to users needs.
Pitkalkulator
It solves the problem of Polish investors, which use revolut because it helps to create yearly statements to calculate tax according to Polish law. It helps a lot of people, at peak there were 200 visits on site per day. It was parsing pdf files provided by revolut and outputting the balance sheet from the investor account. Right now the site is not needed anymore, because revolut introduces csv information for users itself. Source code of the website is still publicly available on github, used technologies are flask and next.js,
Campaing App
Application which allows to create campaigns to collect funds in the form of cryptocurrency using the technology of blockchain. The main benefit of using blockchain to this application is that rules applied to collecting funds are written down in a form of a smart contract and publicly available, so everyone can familiarize oneself with it. Also after deploying no one can modify the contract, so initial rules always apply. The project helps me to get knowledge about the blockchain technology and solidity language, which allows me to write smart contracts, so I can also help clients to utilize blockchain to solve problems. Here is link to the application.
Pomodoro App
A pomodoro application helps to make short or longer breaks during work periods. The idea is based on a time management method developed by Francesco Cirillo. It uses a kitchen timer to break work into intervals, typically 25 minutes in length, separated by short breaks. The application has rich customization settings allowing for changing theme color and font You can try it here link to the application.
