Message

At Kartado, I build full stack RESTful applications with Django and React, supporting PostgreSQL databases that serve 1000+ daily active users. I optimized API endpoints to cut response times by up to 90% and created custom PostgreSQL indexes that reduced wait time for critical queries by up to 50%.

I also implemented asynchronous Excel exports with Zappa and AWS Lambda, reducing export time by 20%, and monitor production systems to maintain 99.95% platform uptime. Earlier at Kartado, I developed Python and Jupyter notebooks to automate customer data modifications; at WEG S.A., I designed an air duct modification that reduced an inverter’s internal temperature by 10%.
