👨💼 About Me
Hello! I am a software engineer with more than 8 years of experience in software development. I have worked in highly competitive sectors such as e-commerce and innovative areas like environmental management, healthcare, construction project management and accounting.
I am proficient in both frontend and backend development, and I excel in both areas. I have experience leading initiatives from start to finish without supervision. I have implemented automated testing systems for quality assurance and have managed database systems with complex SQL queries.
More recently, I've been implementing AI integrations such as PDF data extraction, embeddings vectors, agents, and chatbots to automate processes and enhance user experiences.
I have worked in both software factories and startups, and I greatly enjoy collaborating in high-performance teams and multidisciplinary cells. I believe that teamwork and effective communication are essential to achieving outstanding results.
