Successfully developed the real-time multiplayer game "Arena of Dreams". The project required a robust technical foundation to handle thousands of concurrent users interacting in real-time, demanding high performance, scalability, and observability.I was responsible for:Technology stack: Leveraged C#, Docker, MongoDB, Open Telemetry, Grafana, Prometheus, and Redis to build a scalable and efficient backend.Cloud architecture: Designed and implemented a microservices architecture on AWS, utilizing a wide range of services including EC2, S3, DynamoDB, RDS, CloudWatch, Lambda, ElastiCache, SQS, and SNS.DevOps practices: Implemented a robust CI/CD pipeline using AWS CodeBuild and CloudFormation to automate the build, test, and deployment processes.Performance optimization: Optimized the game engine to ensure smooth gameplay and minimal latency for thousands of concurrent users.Observability: Implemented comprehensive monitoring and alerting using Open Telemetry, Grafana, and Prometheus to ensure system health and performance.

I was involved in all stages of development (architecture, modeling, coding, testing, and production deployment) of various software projects based on wearables (Fitbit and Garmin). During this period, my clients were foreign companies, and my communication with the project team was always in English.The backend utilized a wide range of AWS services (EC2, S3, Dynamo, RDS, CloudWatch, Lambda, ElastiCache, VPC, SES, SQS, SNS, and others), with a microservices architecture and using C# as the primary language, along with NoSQL (DynamoDB) and relational (SQL Server) databases. RESTful APIs were exposed for frontend communication.C and JavaScript were used for applications running on the devices. Both platforms offer a highly constrained execution environment, with limited memory (ranging from 32 to 128 Kilobytes) and very low clock speeds (40 to 200 MHz). This environment was extremely challenging in terms of CPU utilization and memory consumption optimization.Administration websites and user interfaces were built using Angular, Bootstrap, and React. Mobile applications were implemented using React Native.

I was involved in the architecture, modeling, coding, and testing of a system focused on risk analysis in financing operations. The product's primary clients were insurance companies and telecommunications operators.The backend was coded in C#, using an architecture that allows for horizontal scalability, high performance, and the ability to handle massive demands, on the order of thousands of operations per minute.Quality was ensured through the adoption of TDD (test-driven development), with a strong focus on BDD (Behavior-driven development) and Gherkin language. SpecFlow was the chosen tool for test construction.The frontend was coded in JavaScript (AngularJS) and Bootstrap.I participated in the product's development for 8 years (my entire tenure at the company). The agile methodology was adopted throughout the project cycle, and Scrum rituals were strictly followed.I was involved in all stages of the product's lifecycle, from the proof of concept to the first release (MVP), and the entire process of building, improving, and maintaining it. I was actively involved in configuring the CI/CD environment, including automated testing, test coverage, and automatic release generation. Target Process (Jetbrains) was the primary tool for this process.When I left the project team, the product consisted of dozens of independent services, operating and communicating asynchronously, and the software as a whole was composed of over two hundred projects.

I started my journey at this consultancy as a Senior Systems Analyst and left as a Technical Lead.I used English extensively in my day-to-day work. I constantly communicated with development teams in other countries on the projects I worked on.During this period, I coded dozens of projects in various sectors (Manufacturing, Finance, Transportation, Press, Insurance, etc.).I gained a vast amount of experience regarding the specific and common difficulties of clients and worked on understanding business requirements and problems.I implemented best practices and led, from a technical standpoint, several teams at different clients.It was this period of my professional career that solidified my ability to understand and evaluate problems objectively. It taught me to understand the client's perspective and showed me that we need to be pragmatic in our technical approaches.During this period, I worked primarily with Microsoft technologies.
