System architect, tech lead and full-stack web developer

I am an experienced software architect and a tech lead with a track record in designing and delivering systems. Starting back in the day 20 years ago as a full-stack PHP programmer (which was customary back then), I have always valued responsibility and deep understading of tech and business process of every project. During the last 10 years I've been progressing from frontend web development, to full stack, to tech lead and team mentoring, release management of web and mobile projects, and a software architect on multiple projects, including those outside of Upwork. My expertise includes system architecture, mentoring development teams, and building cloud-based solutions using Azure. I have extensive experience collaborating with stakeholders to align technical solutions with business requirements, ensuring high-quality, scalable outcomes and always trying to find a good balance between speed/quality/performance/tech debt in order to achieve current business priorities. I specialize in Azure cloud services, designing secure and cost-efficient architectures that support modern applications. My programming experience spans a wide range of technologies, including TypeScript, JavaScript, Node.js, and .NET, enabling me to adapt to various project needs. I am proficient in setting up CI/CD pipelines, DevOps practices, and development frameworks to streamline and improve project delivery. I have successfully led and mentored developer teams, guiding them in adopting best practices and fostering collaboration across multiple teams. Whether it's reviving stalled projects, creating prototypes, or ensuring technical alignment, I bring a hands-on, results-driven approach to every project. Technologies that I work with professionally are: Software Architecture: Writing design documents/Specification/Technical drawings Business modelling: Domain Driven Design DevOps: Azure DevOps, Bitbucket Pipelines Azure: Container App Environments, Web Services, Azure Storage, Service Bus, Active Directory and authentication, etc Languages: Typescript/JS/C# Backend: .net/nest.js/Swagger API + code generation/GraphQL Messaging systems: Azure Service Bus/AWS SNS/SQS Databases: Mongo DB / MySQL / Postgres / Cloud Databases / Redis Frontend: React / React Native and everything that comes with it If you are looking for an expert in system architecture, Azure cloud, and technical leadership to elevate your project, I’m ready to help.
