Summary
🤩
Rockstar🎓
Top SchoolTim Weller is a Senior Software Engineer specializing in embedded RTOS and kernel services with a strong track record integrating POSIX features, C/C++ runtime support, and low-level debugging for resource-constrained devices. He brings over two decades of embedded systems experience across companies like Mentor Graphics, Siemens, wolfSSL, and Red Lion Controls, blending legacy system knowledge with modern TLS/cryptography work. His open-source contributions to the widely used wolfSSL project include TLS/DTLS 1.3 enhancements, AES-GCM and signature verification work, and UART-oriented buffer handling—demonstrating practical security and IAR toolchain expertise. Tim pairs hands-on cross-compilation and optimization skills with academic depth from an M.S. in Computer and Information Sciences, making him adept at both design and gritty platform debugging. Based in Daphne, Alabama, he quietly bridges industrial control and IoT security, often solving cryptographic and build-chain issues that surface only under real embedded constraints.
