⭐⭐⭐⭐⭐ 40+ successful Angular & .NET projects delivered via Upwork and direct enterprise contracts. I help companies architect, build and optimize enterprise apps that scale. Over the past 8+ years, I’ve worked on SaaS, fintech, healthcare, logistics, ESG, blockchain and enterprise platforms, building clean frontends, strong backends, and full systems that are fast and maintainable. I’m strongest when a project needs both hands on development and senior level architecture thinking. My core stack is Angular, TypeScript, C#, ASP.NET Core, SQL, Entity Framework, REST APIs, and modern cloud based development workflows. I also work with NgRx, Signals, RxJS, SSR/SSG, microfrontends, Nx monorepos, PostgreSQL, MongoDB, Redis, SignalR, Stripe, and role based enterprise systems. 💡 Clients usually bring me in when they need one of these: - a senior engineer to build a product properly from the start - an existing app that has become slow, messy, or hard to maintain - a strong Angular frontend paired with a reliable .NET backend - better architecture, cleaner state management, and more scalable code - someone who can turn Figma designs into polished, reusable components - performance, SEO, SSR, database, or API optimization 💡What you can expect from working with me: - clean, maintainable code - strong communication and reliable delivery - architecture decisions that make sense long term - attention to performance, structure, and code quality - someone comfortable working solo or with an existing team I’ve worked on large scale business applications, multi role dashboards, admin systems, real-time features, payment flows, and enterprise products where stability and code quality matter. 👉 If you need a senior engineer who can both build and think through the bigger technical picture, feel free to reach out.

I'm a senior software engineer with experience in various fields, based in Bosnia and Herzegovina, Europe. Master of science in Automation and Robotics. I specialize in Angular and Java/Nest.js/Python development, while having a lot of experience in other tech. Development skills: Backend/Desktop: - C# (.net core, .net framework) - Python - Java Spring - Nodejs/Nestjs Backends were developed in many different technologies, from MES application backends to real-time monitoring backends using simple data aggregations to multi-service backends integrated together to produce KPIs and other reports. EntityFramework with .NetCore was used for database operations, while SignalR was used for real-time communication. AZURE CLOUD: - IoT Hub - Stream Analytics - App Service - Web Job - Azure Container Registry - Power BI One of my projects was building an entire pipeline starting from a sensor on an industrial machine itself to a visualization in MS Power BI. .NetCore was used to read the data from PLCs using OPC client, then Azure technologies like IoT Hub and Stream Analytics were integrated to move and process the data in Azure Cloud. App Service and Web Jobs were used for various tasks like hosting the Angular applications and WebJob specifically had many usages - from generating periodic e-mails depending on some conditions to generating PDF files with reports and storing them to database. DB: - SQL Server - PostgreSQL - MySQL - InfluxDB - Redis I have several years of professional experience with MS Sql server and PostgreSQL, while in recent couple of years I started also using Redis as a "cache" storage for my applications. Lately, I started working with Flux as well, using it for various KPI calculation for my monitoring application. Application that works with Redis is written in Nest.js while backend working with InfluxDB is Java. Frontend: - Html5 - CSS/SCSS - Angular 11+, Angular 17+ - Vue.js - Nest.js - Node - Chart.js, Highcharts Typical web applications I have built are for manufacturing industry, MES or real-time monitoring applications written in Angular 10+. Most of visualizations were done with libraties such as Chart.js, while for styling I used Material and TailwindCss. MESSAGING PROTOCOLS (used in current solutions): - MQTT - REST - SOCKET - Kafka - OPC UA I have extensive experience with OPC UA protocol for reading PLC data and streaming it to other services using Kafka. I used socket technologies for real-time monitoring applications, transferring machine data from various backends to Angular frontend. DOCKER ENGINE + CI/CD: - Docker - Azure Container Registry - Kubernetes - K3s - Harbor During my time as MES specialist, I worked extensively with k3s on Raspberry Pi devices, ensuring correct deployment and installation of applications. I built a big pipeline in Gitlab which automated the installation of applications from Harbor to k3s cluster hosted on Raspberry Pi devices. These deployments were connected to Rancher. VERSIONING SYSTEMS: - GIT - Azure DevOps - Gitlab

I’m a backend-focused software engineer specializing in C# and the .NET ecosystem, helping clients build, fix, and integrate production systems with reliability and speed. My core work centers on ASP.NET Core–based backend services, Web APIs, and business logic. I’m often brought in to resolve urgent issues, stabilize existing systems, upgrade .NET applications, or integrate new functionality into established codebases. Recent projects include fixing production problems, upgrading .NET versions, and delivering clean solutions under tight timelines. Primary focus areas - C# development and ASP.NET Core Web APIs - Backend services, refactoring, and system stabilization - SQL Server and data-driven workflows - System integrations, webhooks, and third-party APIs - Backend automation and process optimization On the frontend side, I work with Angular for internal dashboards and business tools, and I’m expanding my use of modern JavaScript frameworks (such as React & Vue) to deliver clean, API-driven admin interfaces when a UI layer is required. I’m comfortable working independently, communicating clearly, and taking responsibility for backend-heavy tasks where clients need dependable results rather than experimentation.
