👋🏼 Hi, there! I'm Lucas Da Cruz.

I am a Software Engineer with 4+ years of experience specializing in backend development, API design, and distributed systems. Beyond backend, I have hands-on experience building modern frontends and implementing DevSecOps solutions. My main focus is on building scalable, efficient applications while exploring emerging technologies like AI, robotics, and cloud computing.

At Ecolab, I've delivered impactful solutions across the full stack. I contributed to distributed IoT systems processing real-time data from tens of thousands of devices with automated alerting capabilities. Building RESTful APIs and microservices, I enhanced system performance and reliability. On the frontend, I co-led the delivery of an Executive Business Review application serving 300+ global account managers. I also built infrastructure and developer tooling to improve engineering velocity and system observability.

Beyond my full-time work, I engage in freelance projects with startups and small businesses, delivering automation solutions that drive operational efficiency. At Torchlight, I modernized their test automation by migrating legacy Selenium suites to Playwright, significantly improving reliability and reducing test runtime. I also developed Python tools for concurrent link auditing and built automated report generation mechanisms that reduced manual reporting time from days to just hours.

During my free time, I enjoy learning new technologies, reading books, blogging, cooking, and spending time with my wife and three kids. Check out my projects page to see more of the work I'm passionate about - from backend systems and frontend applications to infrastructure and developer tools.
