I’m a QC Engineer with 7 years of hands-on experience testing web and mobile applications across different industries and complex business workflows. My focus is simple: find issues before your users do and help you deliver a reliable, user-friendly product. I can support your project with: Manual, Functional & Exploratory Testing Web & Mobile Application Testing Regression, Smoke & Sanity Testing UI/UX & Usability Testing API Testing using Postman Database Testing & Data Validation Cross-browser & Cross-device Testing Requirements Analysis & Test Scenario Design Test Case Design & Execution UAT Support Bug Reporting & Defect Management Agile/Scrum Testing AI-based Application Testing Performance Testing I provide clear and actionable bug reports with detailed reproduction steps, expected vs. actual results, severity/priority, screenshots, and screen recordings when needed. I’m experienced with tools and technologies including Jira, AIO Tests, Postman, JMeter, Selenium WebDriver, Java, Jenkins, Git/GitHub, and SQL/database validation. Beyond executing predefined test cases, I enjoy exploratory testing and thinking from the end user’s perspective to identify edge cases, usability problems, and unexpected behavior that may not be covered in the requirements. Whether you need someone to test a new feature, perform regression before a release, review your complete application, support UAT, or provide ongoing QA support, I can adapt to your project and workflow. Available for both short-term testing projects and ongoing QA support.

If your .NET system is becoming harder to maintain, integrations are slowing delivery, or requirements are still unclear, I can help turn the complexity into a reliable, scalable solution that is easier to build, support, and evolve. Software projects rarely become difficult because of code alone. Requirements change. Existing systems accumulate complexity. Integrations create dependencies between teams and platforms. Technical decisions that looked reasonable early in a project can later make every new feature slower, riskier, and more expensive to deliver. The real challenge is turning all of that into software that works for the business, remains manageable for the engineering team, and can be supported reliably in production. Where I usually add the most value Unclear requirements → a practical technical direction When business requirements are still evolving, implementation should not start with assumptions. I work from the problem outward: understanding the workflow, identifying dependencies and constraints, translating requirements into technical decisions, and defining an implementation approach that is realistic for the project. That can include solution planning, API design, architecture decisions, integration strategy, technical breakdown, and implementation itself. Growing codebase → maintainable architecture As systems grow, adding features can become slower because responsibilities are unclear, components are tightly coupled, or the same logic is being rebuilt in multiple places. I work with .NET applications to improve structure, introduce reusable foundations, separate responsibilities, and apply patterns such as Clean Architecture, Domain-Driven Design, SOLID, CQRS, and modular architecture where they provide real value. The objective is not architecture for its own sake. It is to make the system easier to understand, change, test, operate, and extend. Disconnected systems → reliable integrations Enterprise applications rarely operate alone. They often depend on external APIs, internal services, CRM platforms, third-party providers, messaging infrastructure, and other engineering teams. I design and implement RESTful APIs, third-party integrations, and message-based workflows with attention to data flow, validation, failure handling, maintainability, and production troubleshooting. My integration experience includes Microsoft Graph, ClickUp API, Dynamics 365 CRM, RabbitMQ, MassTransit, and multiple enterprise third-party systems. Development completed → production-ready delivery Writing the feature is only one part of delivery. Testing, CI/CD, deployment, environment coordination, troubleshooting, production support, and communication with stakeholders all affect whether software actually succeeds after release. I work across the full software delivery lifecycle — from requirements and technical planning through development, SIT/UAT, deployment, production support, and continuous improvement. Experience behind the approach In my current role at Link Development, I lead technical delivery for a large enterprise government platform across .NET API development, integrations, solution planning, testing, deployment, and production support. My responsibilities include coordinating 13 enterprise integrations, supporting a platform used by more than 500 users, and mentoring engineers across planning, implementation, and code reviews. At Brace Technology, I led engineering teams across multiple projects and designed a reusable modular-monolith foundation using DDD, Clean Architecture, CQRS, MediatR, MassTransit, RabbitMQ, and event-driven architecture. For a US-based software company, I led backend development across multiple projects, built .NET APIs with complex business logic and integrations with Microsoft Graph and ClickUp, and created reusable libraries and shared components to reduce repeated implementation work. Core engineering stack C# • .NET • ASP.NET Core • REST APIs • SQL Server • Entity Framework Core • Dapper • Clean Architecture • DDD • CQRS • MediatR • RabbitMQ • MassTransit • Docker • Azure DevOps • CI/CD • Angular • TypeScript • Dynamics 365 CRM • Microsoft Graph The goal The goal is not simply to deliver more code. It is to understand the business problem, make the right technical decisions, reduce unnecessary complexity, and build software that the team can continue working with confidently after delivery. If you are dealing with a difficult backend, an application that needs restructuring, a complex integration, unclear technical requirements, or a system that needs dependable production support, share the context and the outcome you are trying to achieve. From there, we can determine the most practical technical approach.
