I am a Software Engineer coming from Latvia who started as a self taught Android developer and proceded with a degree in Technical Computer Science at University of Twente ↗️ (The Netherlands). There, I have received in depth theoretical and practical education across Computer Science field, including but not limited to programming paradigms, algorithmics, data structures, compiler creation, machine learning, work organisation, networking. Familiar with ins and outs of Android SDK, and having deep knowledge of Java and Kotlin, including the fundamental OOP principles, I am eager to be creative in my projects to create robust and stable solutions.

Having worked in challenging projects, I am not afraid to take responsibility and dive deep into seemingly non trivial tasks. I build secure and maintainable backends and pipelines with Docker and Python. I have made code contributions to open source data processing pipelines in Spark and Scala. ↗️

As an Android developer, I have built many apps, from simple single screen apps to ones with complex workflows. I care about good UX/UI and enjoy making user interfaces which are modern, fresh, yet familiar to the users.

My priority in building software is making it robust, consistent, verifiable and simple. I enjoy working on projects with well thought-through testing workflows.

As a software engineer, I am learning on my own from official blogposts, conferences, documentation and StackOverflow. I enjoy unpacking complex problems into smaller bits and coming up with elegant solutions.

In my free time I like widening my horizon by experimenting with new techniques, architectures, e.t.c. As a result, over the years I have accumulated a lot of personal projects, most unpublished, some unfinished. Every single on of those taught me some lessons and I am currently trying to revive some of them, at least for demos.

I use Git, Gitlab and Github, Jetbrains IDEs and Linux bash daily. I develop on a personal laptop (OpenSuse KDE).

I speak English(C1), Latvian and Russian (native). I have some very basic understanding of Spanish and Dutch.

When I am not coding I like to do lap swimming, travelling and watching movies.


Google Assistant helper, guide

Lead software engineer (Android and other), project owner.

Android Java/Kotlin Firebase ReactJS Git Bitbucket, Gitlab Code review 4.8 Million Installs

Using Google Assistant may sometimes become frustrating. While it aims to be close to human-like, in practice misunderstandings happen. This app attempts to educate users about what is possible with Google Assistant using a carefully collected and tested database of phrases and commands anybody can say.

For further simplicity, the smart assistant can be invoked directly from the app, and voice recognition settings can be accessed easily.

My responsibility was to design, prototype, implement, publish and oversee growth of the application, working in a team of three (me, a graphical designer, and a data collector). I was the lead Android developer, making most technical decisions.

The objective of this project, funded by EU funds, was to create a tool for law enforcement officers to facilitate investigations into cryptocurrency money flows and illegal activities.

I was the only engineer in data processing department.
Responsible for: setting goals and developing solutions from architecture to deployment; solving challenges related to efficient data scraping, storage, analysis and querying using available scientific recommendations, as well as experimentation.

Student association website Ockham

Backend developer personal desktop

Laravel PHP Gitlab CI/CD Git Bootstrap In production for >2 years

As an university project we had to build an operational, scalable and easily extenable website for one of the student associations in University of Twente.

Working in a team of 6 (2 human computer interaction specialists, 4 developers), we organized our work accoding to Agile methodology, using Scrum poker, daily stand ups and retrospectives.

Issue tracking was done in Gitlab. An extensive CI testing was implemented, with sufficiently high coverage.
Regular code review was being performed by me and my colleagues.

Main requirement for the website was to make it easily extendable and customizable for non technical users, so the architecture had to be highly modular and all visible strings had to come from the database.

Android Kotlin Multiplatform Jetpack Compose / Multiplatform Clean Architecture MVVM DI Laravel Unit testing Gitlab CI/CD Published

Knowledge base of PC keyboard shortcuts (a.k.a. hotkeys) for Android and Desktop.

Using latest design and architecture patterns, I have developed a robust platform-independent codebase that is used to create Android and desktop applications (website is planned too).

The project was designed to provide a great and personalized user experience. Apart from browsing shortcuts across many categories, users are able to add programs and shortcuts to favourites for near-intanteneous access across their devices when needed.

Harry Potter Spells & Quiz

Android developer, 2017 personal desktop

Android Java Published

One of the first projects at SDE Dev, SIA and my debut as Android developer.

Based on an idea from a colleague, we made a simple compilation of spells from the Harry Potter franchise. My colleagues were resposible for collecting the information and images, and suggesting ideas for visual presentation, while I was responsible for programming the app all the way from ground up.

To complement the information provided, we also implemented a small quiz inside the app to test the knowledge.

SMS, Email, Call Scheduler

Android Developer personal desktop

Android Databinding Services Unit testing Published, previous version ~1M installs

An Android app for automating SMS, Emails (Gmail), Reminders, VK and Twitter. Extensively tested in production, a lot of feature requests were received and implemented.

This project back from 2016 gained ample attention during the first phase, before Google Play introduced restrictive SMS permissin policy in 2019, and the app was removed. In 2021 I managed to republish the app, but I had to give up the SMS functionality unfortunately. Hoping to resolve in the future. Two versions can be found below: one current and one from before the SMS permission ban.
