• Mastery of TypeScript plus deep expertise in one or more systems languages (e.g., Rust, Go, C++).
• Proven track record building scalable APIs, robust infrastructure, and developer platforms.
• Deep expertise with databases (e.g., PostgreSQL, DynamoDB, NoSQL) and major cloud platforms (e.g., AWS).
• Strong knowledge of microservices architecture, CI/CD pipelines, observability tools, and the Secure Software Development Life Cycle (SSDLC).
• Familiarity with applied cryptography, Public Key Infrastructure (PKI), and secure backend architectures.
• Exceptional problem-solving skills, clear communication, and the ability to influence technical direction across teams.
