Rafał K. - Fullstack Developer, Tailwind CSS, tailwindcss

My journey at Softaims has been defined by curiosity, growth, and collaboration. I’ve always believed that good software is not just built—it’s carefully shaped through understanding, exploration, and iteration. Every project I’ve worked on has taught me something new about how to balance simplicity with depth, and efficiency with creativity. At its core, my work revolves around helping businesses and people achieve more through thoughtful technology. I’ve learned that the most successful projects come from teams that communicate openly and stay adaptable. At Softaims, I’ve had the opportunity to work alongside professionals who challenge assumptions, share knowledge generously, and inspire continuous improvement. I take pride in focusing on the fundamentals—clarity in logic, consistency in design, and empathy in execution. Software is more than a set of features; it’s a reflection of how we think about problems and how we choose to solve them. By maintaining this perspective, I aim to build solutions that are not only effective today but also flexible enough to support the challenges of tomorrow. The culture at Softaims promotes learning as an ongoing process. Every new project feels like a step forward, both personally and professionally. I see each challenge as a chance to refine my skills and contribute to the shared vision of building technology that genuinely improves lives.

Experience Highlights

Map of cold damage and costs in USA

The interactive map of cold damage costs and heating costs in United States is based on a MongoDB database populated with data scraped from United States Census pages. The map is created in Leaflet.js, with interactive elements managed with D3.js.

Public Shopify app for logistics management

The project involved end-to-end creation of a public Shopify app for assisting Shopify store owners in management of their 3PL/warehouse network and order management. The scope of the project was from initial design and mockup to deployment of the application to an Ubuntu server, submission to the Shopify App Store, and subsequent maintenance. The application was built on MERN stack, deployed to an Ubuntu server, and utilized Shopify GraphQL APIs and two other custom APIs to obtain granular data regarding warehouse, inventory and order routes.

Custom analytical visualization of inventory value

The client required a custom solution for analytical visualization of their inventory based on their warehouse API. The visualization is based on data saved and regularly updated in a MongoDB database, based on repeated API calls to the warehouse provider and similar API calls to Shopify store.

Inventory and payout management tool

The client, owner of several Shopify and FBA stores, requested creation of a comprehensive inventory and payout visualization based on the total value of all of their inventory throughout all of their stores and warehouses. The application, utilizing D3.js for the visualization side and Node + MongoDB for the backend and database respectively, utilizes several APIs of Shopify, Amazon SP-API and different warehouse providers to retrieve inventory numbers and values and update the state of the inventory every day.

Custom inventory state visualization

The project involved creation of a custom visualization based on inventory statistics retrieved from a warehouse API and saved to a MongoDB database. The visualization allows the user to analyse the status of inventory and look up detailed inventory and order history for individual articles.
