About Me

Experienced Web Developer specializing in building robust and scalable web applications with Python, utilizing powerful frameworks like FastAPI, Flask, and Django. With over 10 years of experience in web development, I bring a strong foundation in understanding client needs, delivering functional solutions, and ensuring project success.

My journey into coding began at 17 with that first "Hello, World!", and I quickly gravitated towards Python for its elegant syntax and versatility. That initial spark continues today, driving me to constantly explore new developments within the Python ecosystem and modern web standards to ensure I'm using the best tools for the job.

My approach focuses on understanding the core business need before diving into technical solutions. I prioritize clear communication throughout the project lifecycle and believe strongly in writing clean, maintainable code that stands the test of time.

While I enjoy the full stack, I particularly relish tackling complex backend challenges, especially those involving data integration. At the same time, I find great satisfaction in building intuitive user interfaces that make powerful applications easy to use.
