    I am a seasoned Full Stack Developer with over 9 years of experience in crafting robust and secure software solutions. I started with traditional languages like C# and Java and have since expanded into various languages like JavaScript, Ruby, and Python. Throughout my career, my primary focus has been on building highly secure platforms and maintaining codebases that are easily testable through unit testing. My extensive knowledge extends to both SQL and NoSQL databases, including Oracle, PostgreSQL, MySQL, MongoDB, and AWS DynamoDB. I have a deep understanding of database design and optimization, which enables me to create efficient and scalable data solutions. In recent years, I've immersed myself in blockchain technology and DeFi, staying at the forefront of this rapidly evolving field. I'm also a proficient user of AWS cloud services for deployment and continuous integration/continuous deployment (CI/CD) pipelines. I've worked with a wide array of AWS services, including but not limited to ECS, EKS, EC2, API Gateway, and Lambda, enabling seamless deployment and scaling of applications. My technology stack is versatile: Frontend: React.js(Next.js and Gatsby.js) and Angular Backend: Java Spring Boot, TypeScript Node.js (Nest.js), PHP Laravel, Ruby on Rails Architecture: Microservices, messaging with Kafka Database: Oracle, PostgreSQL, MongoDB, AWS DynamoDB, Redis DevOps: Docker, Kubernetes, AWS services I'm always eager to learn new technologies and deliver top-notch results. Let's work together to achieve your goals in software development! ít hơn

    I am an experienced and passionate system architect and developer. My main areas of expertise are: .NET: C# 6, VB.NET, Azure, ASP.NET, MVC, WPF, WCF. Web API, LINQ. Databases: SQL Server 7 - 2014, Oracle 9-12. NoSQL: MongoDB, ElasticSearch. Client side: Javascript, AJAX, JQuery, Angular and React. I am a huge MVC follower. I consider this framework the best web dev tool from Microsoft, because it clearly separates the business logic from presentation, solutions are easy to develop and maintain. Ecommerce: I have extensive experience customizing nopCommerce system, building plugins and setting up turn-key shops on the web using this opensource .NET platform. CMS: I have set up a number of sites using Orchard CMS, both for internet and complex intranet systems. I have experience in mobile development. I developed a couple of game apps using Xamarin Studio. This is a fantastic tool which helps us develop native iOS, MacOS and Android games with the Microsoft .NET technology stack. With MVVM Cross we maintain single backend codebase for apps on different mobile platforms. I have exposure to games and virtual reality apps development with Unity3D. Please see portfolio for more samples. Having a university degree in computer science, I value customers who appreciate efforts invested in using OOD patterns, utilizing full strength of OOP and UML modelling. Analyzing business requirements and producing technical specs is something I was doing for the last 10 years. I lead software teams that provide full cycle of software development. I am not interested in "one hour" or "one-day" jobs. I establish long-lasting relationships with my clients. I always consider commitment to the result as the first priority. ít hơn
