# Brendan K. > Full-Stack Engineer (React/TS · Node/NestJS) | AI Agents & RAG Location: Napa, California, United States Profile: https://flows.cv/brendank I build clean, reliable products across the stack: React/TypeScript on the front, Node/NestJS on the back. Lately I’ve been adding AI features that actually work in production—agents that call tools, remember context, and automate real workflows. I favor clear architecture, typed contracts, and measured delivery: REST/GraphQL APIs, DTO validation, job queues (BullMQ/Redis), and CI/CD with meaningful tests. I care about performance, accessibility, and DX. Recent focus: LLM agents, RAG over Qdrant/Supabase, prompt design & cost controls, and observability. Keywords: Node.js, NestJS, TypeScript, React, GraphQL/REST, PostgreSQL, Redis, BullMQ, LangChain.js, OpenAI, Qdrant, Supabase, Jest, Docker, AWS/GCP. ## Work Experience ### Software Engineer @ MonetizeNow Jan 2021 – Present I successfully contributed to the development of a multi-tenant SaaS billing platform that streamlined revenue management processes. • Built responsive UI components and integrated advanced reporting features for improved analytics. • Managed a large-scale Nx monorepo, ensuring high code quality and efficient collaboration. • Established CI/CD pipelines to automate testing and deployment, enhancing development efficiency. ### Back End Developer - Freelancer @ upwork Jan 2019 – Jan 2020 I focus on delivering high-quality back-end solutions that drive efficiency and performance. • Cut API p95 latency from ~800 ms to ~260 ms through effective caching and connection pooling strategies. • Reduced LLM token spend by approximately 25% by implementing prompt templates and response post-processing. • Introduced contract and end-to-end tests, preventing regressions and accelerating delivery timelines. ### Senior Software Engineer @ IoTfy Jan 2018 – Jan 2019 | United States Developed hospital patient management system leveraging Particle.io IoT devices to collect and monitor sensor data such as room occupancy and vital signs. Designed APIs to control IoT devices remotely and trigger alerts based on sensor thresholds, improving healthcare staff responsiveness. Built web-based real-time control panels using Vue.js for monitoring and managing IoT device events. Integrated AWS IoT Core services for device communication, event processing, and secure data streaming. Ensured scalability and reliability of the IoT platform through modular architecture and asynchronous event handling. ### Full-Stack Engineer (Remote) @ Captable, Inc. Jan 2016 – Jan 2018 Developed and maintained full-stack web applications using Node.js, TypeScript, React, and Vue.js, delivering scalable and maintainable codebases. Architected RESTful and GraphQL APIs, integrated real-time data streaming with WebSocket for trading platforms such as Binance and Bittrex. Built and deployed smart contracts in Solidity and dApps using Web3.js and Ethers.js, including ERC-20 and NFT standards. Created trading bots based on market arbitrage and signal algorithms, improving client trading efficiency and automation. Integrated wallet solutions with MetaMask and Coinbase Wallet for secure user authentication and transaction signing. Applied best practices in testing with Jest and Cypress to ensure robustness and reliability of applications. Utilized cloud infrastructure on AWS (Lambda, DynamoDB, S3, API Gateway) for serverless backend deployments. ## Education ### Bachelor's degree in Computer Science Auburn University Jan 2012 – Jan 2017 ### Bachelor's degree in Computer Software Engineering Zhejiang University Jan 2011 – Jan 2012 ## Contact & Social - LinkedIn: https://linkedin.com/in/brendan-kam-np - Website: https://brendankam.dev/ --- Source: https://flows.cv/brendank JSON Resume: https://flows.cv/brendank/resume.json Last updated: 2026-03-29
