About

Professional summary

I am a Senior Software Engineer with over 3.5 years of experience building enterprise web applications and full-stack software solutions.

I work across frontend, backend, and database layers, developing REST APIs, responsive user interfaces, role-based dashboards, and administrative workflows. My primary stack includes C#, ASP.NET Core, React, TypeScript, and relational databases.

I have experience in system design, clean architecture, database design, query optimization, application performance, and scalability. I investigate technical issues through root-cause analysis and implement maintainable solutions.

I have contributed to architectural decisions, including database sharding for high-volume workloads and Stripe payment workflow design and implementation. I have also improved slow API performance by identifying inefficient queries and server-side processing bottlenecks.

I value testing, code reviews, technical discussions, and collaborative problem-solving. I have worked closely with developers, QA engineers, technical leads, and stakeholders to deliver reliable software.

I am also an active competitive programmer, having solved more than 1,200 problems and participated in over 100 online contests.

Career history

Senior Software Engineer L2 Enosis Solutions

I contribute to architectural and technical decisions by evaluating database design and query-processing approaches to improve application performance, scalability, and maintainability.

I collaborated with the Technical Lead to design and implement database sharding for high-volume workloads. I also investigate issues across application and database layers, perform root-cause analysis, and drive issues through resolution.

Senior Software Engineer L1 Enosis Solutions

I designed the Stripe payment workflow and collaborated with the Technical Lead on the implementation approach. I integrated payment processing, validation, and transaction-related business logic.

I investigated slow API responses, identified inefficient database queries and server-side processing bottlenecks, and reduced response times from approximately 800 ms to 80-120 ms. I also optimized server-side filtering and data-processing workflows.

Software Engineer L2 Enosis Solutions

I developed full-stack features by translating business requirements into frontend workflows and backend functionality. I designed and implemented REST APIs, role-based dashboards, and administrative features.

I wrote unit tests and performed API end-to-end testing to validate backend logic, API behavior, and critical application workflows.

Software Engineer L1 Enosis Solutions

I implemented frontend and backend features based on business requirements and existing application workflows. I built API endpoints, database changes, and responsive user interfaces for new functionality.

I investigated application issues during development, reproduced defects, and implemented fixes for production releases.
