My journey in the tech world has been both challenging and rewarding, allowing me to hone a diverse set of skills and work on various exciting projects. Expertise: Frontend Development: With 2 years of experience using Next.js and React, I specialize in building intuitive and responsive user interfaces. I take pride in creating seamless web experiences that delight users and meet business goals. Proficient in HTML and CSS to ensure pixel-perfect designs. Backend Development: I have 3 years of experience developing robust backend systems using NestJS, Deno, RestAPI, and GraphQL.

As an infrastructure engineer, I transitioned into roles involving the IaC of GCP and AWS resources using Terraform. I also focused on the security, DevOps, and operational monitoring of various internal products, ensuring robust and secure infrastructure foundations. Most recently, I have been involved in internal architecture improvements, where I have gained valuable experience in RDBMS table design, non-functional requirements definition, domain model segmentation, and transitioning to microservices.
