30 minute consultation
I had a wonderful experience working with Oleksandr's team during the consultation for an AI voice agent. He was able to answer all of my questions in depth, offering useful insights and recommendations that were specific to my business. Oleksandr's knowledge about AI agents is extensive, to say the least, and it is valuable for anyone who needs advice on AI and LLM integration. It was also great to see solid expertise with platforms such as ElevenLabs, Twilio, and Azure, which are essential in developing effective AI voice agent solutions.
Oleksandr is a good communicator, making complex topics sound simple, and was very collaborative in our work together. I also appreciate his focus on quality and solution-oriented mindset. Will certainly reach out later, when it comes to implementation!

Lviv, Ukraine - 12:10 am local time
I specialize in delivering end-to-end solutions using .NET, Angular, Azure, and AI-driven technologies, combining strong backend architecture with modern frontend experiences.
As a .NET Developer, I build robust backend systems using .NET Core and ASP.NET Core, design clean RESTful APIs with WebAPI, develop enterprise applications with ASP.NET MVC, integrate services via WCF, and create cross-platform solutions with Blazor and .NET MAUI.
On the frontend, I craft dynamic and responsive interfaces with Angular, React, and Vue, using TypeScript and JavaScript alongside HTML5 and CSS3 (Less/Sass). I enhance usability and state management with Redux and build polished UI experiences with Bootstrap, KendoUI, jQuery, and KnockoutJS.

I work confidently with relational databases such as MSSQL, MySQL, PostgreSQL, SQLite, and MariaDB, and build high-performance distributed systems using MongoDB, ElasticSearch, DynamoDB, CosmosDB, CouchDB, and Redis.
Choosing the right storage strategy is always driven by ⚙️ performance, scalability, and long-term maintainability.
☁️ Cloud & DevOps
As a .NET Developer, I deploy and maintain solutions across Linux, macOS, and Windows environments.
I build cloud-native applications on Azure, AWS, Google Cloud, Heroku, and Digital Ocean, using Docker for containerization and managing CI/CD pipelines with MSBuild. For frontend automation and build processes, I work with Webpack, Gulp, Grunt, Bower, npm, and yarn.
