A full-stack engineer passionate about building fast, scalable web applications with React, Next.js, and modern technologies, with a focus on AI-powered features and seamless user experiences.
I'm Faisal Salim, a Full-Stack Engineer with 9+ years of experience delivering AI-integrated, scalable, and high-performance web solutions. Specialized in modern web technologies including ReactJS, NodeJS, SolidJS, NextJS, ExpressJS, Redux, TypeScript, and asynchronous JavaScript. Strong background in building LLM-powered features, integrating streaming APIs, and deploying intelligent systems using Python and JavaScript. Worked with clients like Aramco, EdgeUnity, Deloitte, and others across diverse domains. Proven ability to lead teams, manage clients, and ship robust full-stack systems.
I'm interested in working with teams that prioritize excellence - where engineering is treated as a core advantage, not a support function. If you're building at that level, I'm always open to a conversation.
Professional experience that I have accumulated over several years.
Operated as a high-impact full-stack engineer delivering production-grade SaaS and enterprise applications across multiple domains including procurement, energy tech, and fintech. Architected and scaled applications end-to-end using modern serverless and edge-first infrastructure. Built and launched multiple SaaS platforms from scratch, driving real user adoption and business value. Led cross-functional teams, optimized engineering workflows, and consistently delivered performant, scalable, and maintainable systems.
Engineered and scaled complex web platforms including identity management systems and learning platforms used in high-stakes environments. Delivered robust frontend and backend systems across React, Vue, and Angular ecosystems. Played a key role in improving engineering velocity and product quality through strong ownership, test automation, and collaboration with product teams. Led onboarding initiatives and contributed to measurable gains in team productivity and delivery timelines.
Delivered full-stack solutions across multiple client projects, contributing to both frontend and backend systems. Collaborated directly with clients to translate business requirements into scalable technical implementations. Took ownership of technical documentation, product specifications, and proposal development — operating beyond typical engineering responsibilities to influence product direction and client success.
Built a strong foundation in software quality assurance through rigorous testing, data analysis, and compliance auditing. Designed test datasets and conducted detailed reporting to ensure product reliability and adherence to standards. Developed a deep understanding of system behavior, edge cases, and quality processes that later informed robust engineering practices.
