Summary
👤
Senior🎓
Top SchoolSteven Kalt is a senior full-stack engineer with 11 years of experience building scalable web and cloud systems, currently focused on climate tech from Philadelphia. He blends hands-on frontend work—contributing improvements to popular open-source Vue components—with backend and DevOps expertise, having hardened ASGI Lambda adapters and streamlined CI/CD and Terraform workflows. At REsurety he architected terabyte-scale energy market visualizations, replaced fragile IAM policies with concise, maintainable alternatives, and reclaimed ~100 TB of storage to cut costs. Comfortable across the stack, he brings a practical security mindset (AWS SSO, MFA, private networks) and a knack for developer ergonomics—compiler toolchains, linting, type checking, and reproducible dev environments. Known on GitHub for pragmatic fixes and test-first improvements, he jokes he’s an “expert at not knowing things,” which fuels a curiosity-driven approach to solving unfamiliar problems.
