Conducted internal and customer interviews to identify and prioritize optimizations that removed major pain points in deploying and scaling integrations with Keyfactor’s core products; follow-up interviews showed measurable improvements in customer deployment speed and reliability.

Combined understanding of customer pain points with product and technical context to guide features that reduced deployment friction and enabled long-term scalability.

Identified a major inefficiency in deploying lab workspaces, where deploying Keyfactor’s products typically required 2+ hours of specialized work across many skill domains. Designed and built the Simple Environment Service to reduce this to under 10 minutes, providing fully configured, batteries-included environments without requiring domain expertise. Championed adoption across the company, with over 20% of staff using the service to launch 100+ environments on 40+ nodes, handling 1.8M+ daily HTTP requests and ingesting 68M+ log records per day.

Recognized widespread frustration from customers and engineers caused by inconsistent documentation across 100+ integrations. Developed a standardized documentation format and parser that separated content from presentation, allowing engineers to focus on code while ensuring customers received clear, uniform docs. Championed the approach within the team and drove adoption across 100+ repositories, improving readability, reducing maintenance overhead, and accelerating updates.

Researched and documented how 30+ DevOps tools use X.509 digital certificates, building a knowledge base that accelerated responses to customer technology inquiries for the Solutions Engineering team.

Wrote Kubernetes controllers to extend cert-manager issuance capabilities to Keyfactor Command & EJBCA.

Wrote HashiCorp Vault PKI engine to extend Vault PKI features to Keyfactor Command & EJBCA.

Wrote Terraform provider to enable configuration & certificate issuance with Keyfactor products.

Designed mission profiles for each sub-system on board EagleSat-2 to implement the required satellite functionality. Mission profiles are implemented with finite state machines that maintain nominal satellite operation while EagleSat-2 is not in contact with the ground station on ERAU's campus.

Configured and managed the On-Board Computer (OBC) real-time operating system (FreeRTOS with CMSIS RTOS V2 API) and developed low-level drivers for serial communication (CAN, UART, I2C).

Led the communications sub-system team for the EagleSat mission, leading the design, development, and integration of a full-stack satellite communication framework to implement command and control (C2) over EagleSat-2.

Designed and implemented a headless UHF ground station and a packet-radio communication application (C++) to handle packet routing between the primary C2 platform and the satellite, provide connection statistics, detect satellite range, and calculate Doppler shift.
