With a background in sales leadership and high-performance team management, I transitioned into software engineering because I saw the potiential the industry had when it came to increasing productivity.
With all the amazing people I got to meet in my sales journey, I realized that Tech was and will always be part of our future. So I made the hard decision to start from scratch and start builiding. I always knew that if I could persevere as one of the worst sales rep that my company ever had with making one sale per week to going to 30 sales per week and becoming the top performer in the country on multiple occasions that I could learn the ropes in software enginnering.
Now I build scalable applications and cloud-based solutions. I have experience in microservices architecture, cloud deployments, and API development, with expertise in Spring Boot, React.js, Node.js, and Docker.
