What I'm looking for

I am looking for a role that values innovation, collaboration, and continuous learning.

I'm a Full Stack Developer with a strong focus on building highly maintainable and asynchronous products using Node.js, Express.js, and React. My experience includes designing APIs, managing relational and analytical databases like PostgreSQL and ClickHouse, and delivering clean front-end user experiences. I thrive in fully remote, goal-driven environments and have contributed to various SaaS platforms and financial tools, always ensuring high ownership and test coverage.

At BetterWorld Technology, I developed scalable, multi-layered digital solutions using JavaScript and Microsoft .NET technologies. I built and maintained React dashboards with Redux and RxJS, developed backend APIs in Node.js and .NET Core, and participated in sprint planning and continuous delivery workflows. My previous role at NuWare involved delivering full stack features for enterprise projects, where I migrated legacy projects to .NET Core and implemented access control across modules.

As a Freelance Developer on Upwork, I delivered full stack modules for web clients, designed PostgreSQL schemas, and built frontend interfaces with reusable components. My key achievements include optimizing ClickHouse for financial workflows and mentoring junior engineers on Node.js projects. I am passionate about clean code and effective collaboration, and I continuously seek opportunities to enhance my skills and contribute to innovative projects.
