Latest Projects

Cloud Service for interacting with IoT devices - Customer project 2024

My main responsibilities were to design and implement a cloud service architecture in Azure for communicating with IoT devices. We decided to use Hasura GraphQL Engine on the API layer to streamline basic data CRUD operations. It turned out to really speed our development tasks and we used Azure Functions for any operations that required more business logic. Hasura (v2) works out-of-the-box with the PostgreSQL database so that was chosen for the data storage.

The API and frontend (NextJS SPA) were deployed to Azure Kubernetes Service using Azure DevOps Pipelines. I had a chance to improve my CI/CD skills as well with the pipeline development.

Also, I participated in building a demo application in Python for the IoT device and testing MQTT communication between the device and cloud.

Reporting application - Customer project 2023

I was responsible for building a reporting application for a customer’s developer platform. The task consisted of data ingestion from a developer platform in AWS to Microsoft Power BI reports. An infrastructure built with AWS CDK to deploy several components and transform JSON data to Parquet files and store them. Integration from Power BI to Amazon Athena for querying data and building visualisations.

Admin application build - In-house project at Dicelight 2020-2021

I had a significant role building an admin view and several backend features for a lottery management application. The admin view was part of a NodeJS application deployed to Azure Web Apps exposing a set of REST APIs. The UI was based on a Figma design and built using React. The main tasks were to create views and new REST endpoints and backend logic for authentication flow, lottery management, starting a lottery run (updating the view in almost real-time) and storing data in a PostgreSQL database. This was a really rewarding project which gave a chance to design and build end-to-end infrastructure for a cloud-based application.

History

Typescript has been my main programming language since 2020. Prior to the developer platform project I used Typescript to build a data / integration platform in the event management industry. This was a NodeJS application deployed to Azure Functions using CosmosDB as the data storage.

For the first 10 years of my professional career my main focus was in backend development using Java/Spring. Of course nearly every project I’ve done has included some frontend tasks too.
