Background

About Joseph Caballero

I’m a Full-Stack Engineer and Director of Engineering & Product Development with a relentless drive to build systems that scale, solve real problems, and leave people better than I found them. Fluent in JavaScript, TypeScript, Java, HTML/CSS, and frameworks like React, Next.js, Vue, Express, Spring Boot, and Maven – I specialize in crafting full-stack solutions that move fast and stay maintainable. I build clean architecture, integrate real-time features, and guide development from zero to launch with precision. Currently, I hold three active roles- Director of Engineering & Product Development at Arplans – where I architected the company’s entire tech stack from the ground up. Using Next.js, Node.js, MongoDB, and Socket.IO, I implemented real-time infrastructure and built scalable features that directly serve early-stage product growth. I led junior devs, aligned vision with stakeholders, and translated business needs into sharp, working code- Equity-Based Engineer at Secured Health – where I contribute across full-stack development, system design, and QA. I work with PostgreSQL, Prisma, tRPC, and Cypress to ensure functionality and stability at scale. I started as an extern but quickly became the go-to for teammates and leadership alike – easing the CTO’s load and anchoring high-pressure deliverables- Tech Lead Consultant at Code Differently - I co-lead a full-stack software engineering bootcamp for 20+ adult learners, serving as both mentor and technical lead. I guide students through real-world development by reinforcing fundamentals, translating client needs into achievable goals, and supporting delivery through architectural guidance, pair programming, and hands-on debugging. I keep teams aligned across externships and lead with steady, growth-minded guidance rooted in ownership and consistency. My foundation was forged at Code Differently’s Full-Stack Bootcamp, where I wasn't just a student – I became a mentor. I helped others debug, problem-solve, and break down complex systems, earning trust as a natural leader and collaborative force. I also completed Scrum training, embedding Agile and delivery focus into my workflow. Before that, I interned at JPMorgan Chase & Co. as a QA Engineer, where I researched and implemented Cypress for scalable E2E testing – presenting my findings to peers and senior leaders alike. Outside of tech, I train as an aspiring boxer - a discipline that sharpens my edge, builds resilience, and reinforces the mindset I bring into engineering: calm under fire, precise under pressure, always improving.
