What I'm looking for

I seek a collaborative environment where I can leverage my full stack skills to create impactful software solutions.

I am a Full Stack Engineer with a strong background in developing scalable web applications and APIs. Over the past several years, I have honed my skills in both frontend and backend technologies, enabling me to deliver high-quality software solutions that meet user needs and business objectives. My experience includes architecting REST APIs, implementing complex features, and enhancing user experiences across various platforms.

At InstaLOD, I played a pivotal role in integrating multiple projects that supported over 20,000 users. I designed and implemented a custom OAuth2/OpenID Connect-based consent flow, developed e-commerce features, and built high-performance applications using React and TypeScript. My commitment to quality is evident in my thorough testing practices and my ability to streamline development processes through effective use of CI/CD pipelines.

With a degree in Information Systems and a diverse technical skill set, I am passionate about leveraging technology to solve real-world problems. I thrive in collaborative environments and am always eager to learn and adapt to new challenges. I am excited to contribute my expertise to innovative projects that push the boundaries of technology.
