# Wing Man L. > Software Engineer Location: San Francisco, California, United States Profile: https://flows.cv/wingmanl I’m a Software Engineer with experience building full-stack applications using React, Node.js, TypeScript, JavaScript, and Express. I’m passionate about using technology to solve real-world problems and enhance user experiences. As a collaborator on the open-source project TkyoDrift, sponsored by OS Labs, I’ve contributed to developer tools focused on AI drift detection. I recently gave a tech talk on TypeScript, sharing insights on static typing and modern JavaScript development with the engineering community. My background in product improvement and technical support has shaped a user-first mindset and strong cross-functional collaboration skills. Outside of coding, I enjoy repairing gadgets and modifying vehicles—hands-on work that fuels my curiosity in emerging tech like autonomous systems. I’m always excited to learn, build, and grow with innovative teams. ## Work Experience ### Software Engineer @ TkyoDrift Jan 2025 – Present • Built Tkyo Drift, an open-source drift monitoring tool helping developers track LLM input/output shifts across time. • Created backend systems for dynamic embedding storage, drift metric calculations, and scalar feature logging using Node.js and PostgreSQL. • Integrated Node.js and Python seamlessly to build high-speed nearest neighbor graphs (HNSW) for drift analysis. • Refactored critical logic for embedding validation, error handling, and cosine/euclidean drift metrics to improve robustness. • Worked hands-on with Transformers pipelines, PostgreSQL, Docker, and OpenAI/HuggingFace APIs. • Focused on building scalable, modular architecture for real-time drift detection and future product extensibility. ### Freelance QA Tester at Testlio @ Testlio Jan 2024 – Present Testing-as-a-Service for some of the world’s largest and fastest-growing consumer app providers.
