Millions of users each day are interacting with my work.

Who am I?

Hi, I’m Aleksandar, web and mobile developer .

Over the past decade, I have founded, led, and delivered cross-platform mobile apps, enterprise clinical platforms, and high-traffic media systems. My work is used by millions — from fitness app users tracking daily workouts to clinical investigators streamlining trial workflows, and even powering internal distribution systems for Disney+.

Throughout my career, I have built and shipped production-grade apps with React Native, TypeScript, Expo, Node.js, Express, PostgreSQL, AWS (Lambda, ECS, S3, SQS, Chime), .NET Core, C#, GraphQL, Apollo, Redis, ElasticSearch, and RabbitMQ. I have architected offline-first mobile experiences, real-time video conferencing, secure eConsent and media capture pipelines, background job processing with Bull queues, and AI-powered personalization using vector search and OpenAI. I’ve also delivered full-stack web solutions with React, Next.js, Angular, and ASP.NET Core — from custom CMS platforms to scalable REST and GraphQL microservices.

I am highly proficient in modern cloud infrastructure and DevOps, including Docker, CI/CD pipelines, and serverless architectures. I write clean, testable code with Jest, Cypress, Mocha, and Storybook, and I believe in component-driven development, automated pipelines, and resilient sync strategies that work offline first.

I’m a founder-minded team player. I’ve led teams of engineers, mentored developers, and run sprint planning, architecture reviews, and technical onboarding. I take ownership of products from concept to App Store and Google Play. I love solving hard problems — whether it’s making a clinical app work reliably in a basement with no signal, or shipping a fitness AI feature on a tight deadline. I stay positive, move fast, and never stop learning.

Projects I am proud of

Dotnet CLI

Recently I wrote about how good angular works with .net core. And since I already went through that exercise I decided to share some of my experience with the Dotnet CLI and how to get your dotnet application up and running.
