Hi! Welcome to my profile. I am a versatile technology and creative professional with over 15 years of experience spanning full-stack software engineering, desktop application development, graphic design, and technical translation. I'm currently pursuing a Bachelor's in Computer Software Engineering, complementing hands-on expertise in Python, C++, and multiplatform application development. As a Top Rated Upwork freelancer with a 100% Job Success Score, I have successfully delivered web and desktop solutions, audio/video workflow automation, and Portuguese-English technical translation to international clients. My background also includes a strong foundation in open-source contributions, such as Audacity project. In addition to my technical skills, I am also fluent in Portuguese and have experience translating a variety of texts including websites, documents, and marketing materials. With a strong background in graphic design, I pride myself on my attention to detail and ability to accurately convey the meaning and tone of the original text. Overall, I am a motivated and versatile individual with a passion for technology and language. I am confident that my combination of technical, graphical and linguistic expertise makes me a valuable asset to your project. RECENT An AI video dubbing pipeline with transcription, translation, voice cloning and audio separation. Python bindings for libobs. A realtime restaurant order system. A map-first real-estate marketplace on Django and GeoDjango. A Qt6 reporting module for a medical-data platform, ongoing since 2023. Two published Grav plugins. Top Rated Plus, 101 jobs, 44 reviews. Five clients active right now; the longest running since 2021. Most of my work is not a one-off project — it is making a half-finished codebase production-ready, then staying on to maintain it.
