Slopify is a music application that continuously generates AI music based on each user's evolving taste profile and preferences. As the founder and solopreneur, I was responsible for everything from ideation and business analysis to engineering and infrastructure. I singlehandedly shaped the user experience, designed and built new features, analyzed adoption metrics, and made data-informed decisions to drive the product's growth and overall quality.

Evidentree is a healthcare software product focused on evidence-based supplement, condition, and healthcare provider discovery. My role was to evolve the Flutter mobile app and Supabase backend while working directly with the founder to evaluate architecture options, technology trade-offs, and delivery paths. I implemented core product systems across Riverpod state management, Postgres migrations and RPCs, Supabase Edge Functions, scheduled data-sync jobs, analytics integrations, and a React-based internal CMS. The work also included shaping recommendation and personalization flows from in-app activity, hardening external medical-data ingestion, building new UX flows, and supporting reliable staging and production releases.

This was a public transportation startup targeting both passengers and drivers where my role was to deliver two MVP mobile applications that would work together alongside the pick-up and drop-off processes and I built the entire architecture that holds up both roles and multiple flavors and implemented the majority of features and layouts, including in-app purchases with Stripe, map integration with a mixture of Mapbox and Leaflet, and a ride process with real-time updates.

A cross-platform wellness product spanning iOS, Android, a Flutter web CMS, and a Firebase back end. I owned the architecture and delivery end-to-end as the sole engineer driving the product, building the mobile app, the internal content-management tools, and the back-end services that power onboarding, personalized program progression, guided media playback, notifications, analytics, and commerce. The platform combines audio and video sessions, dynamic plans, deep links, push/email engagement, and Shopify Plus in-app purchase flows, and I was responsible for turning product requirements into a scalable, production-ready system across environments and releases.

A classic scooter-sharing application mainly targeting the Czech Republic market. It covers a broad set of functionality, ranging from identity validation and booking to payments via different methods and rendering dynamic objects on the map.

As a lead Flutter engineer, I designed the architecture from the ground up by following clean architecture principles, participated in making important product-related decisions, helped the client save money by providing detailed consultancy about optimization options, and guided designers and back-end engineers with platform-specific expertise.

I led the refinement of a social media platform on Flutter for Web, iOS, and Android, focusing on enhancing core functionalities and user experience.

A set of small loan-processing applications targeting different countries: Sri Lanka, Kenya, and India. I built them from the ground up by developing an internal development kit consisting of reusable modules for these kinds of products. This allowed speedy delivery and expansion into other countries by simply assembling them from those modules with product-specific tweaks and customization. The most notable features include lengthy registration and forms processing, online support service, tracking of current loan statuses and payments, and new loan application with on-the-fly calculations.

This is a mobile application for sports betting, gambling, and online casinos. Developed as a symbiosis of Vue Native and React Native since it was originally ported from a web app based on Vue.js. I was responsible for a complete design overhaul and transition to cross-platform technologies (React Native) while preserving the original business logic from the web app.

A health and beauty industry startup with applications for two roles: masters and their clients. I built React Native-based applications for each role with unique functionality that revolved around booking appointments in the calendars and numerous social media features, i.e., feeds, portfolios, chats, and reviews. Additionally, there was a third, separate app for masters to manage their bonus programs which I insisted on developing with Flutter since it was relatively small.

A personalized food recommendation app that helps find restaurants or dishes specific to the user's taste, desires, and preferences. I rebuilt an Android Flutter-based application from a few years of deprecated state by using up-to-date SDKs to introduce new features and improve the existing ones. As a result, I initially delivered the well-polished app to the Google Play Store.
