Hi, I'm
Ayush Sahay
I'm a Software Engineer (SDE 1) at Kalvium, building full-stack products with React, Next.js, and TypeScript. I care about shipping real user value, growing fast in tech, and embracing AI as a force multiplier for building smarter, faster, and better.
About Me
Software Engineer (SDE 1)
I'm a Software Development Engineer (SDE 1) at Kalvium, working as a full-stack developer focused on modern web technologies like React, Next.js, and TypeScript. Over the past year, I've designed, built, and shipped production features end-to-end—from crafting robust APIs and data models to delivering polished, high-performance user interfaces.
My strengths are rooted in strong programming fundamentals, data structures, algorithms, and clean software design. I'm experienced across the MERN and TNT (Tailwind + Next.js + TypeScript) stacks, and have also worked with Vue and Angular when needed. I'm comfortable across multiple languages including Java, C++, JavaScript, TypeScript, Python, and Go.
I also have hands-on experience with cloud and engineering infrastructure, including Docker, EC2, CI/CD pipelines, cloud functions, batch jobs, containers, monorepos, and process management tools like PM2. Alongside that, I actively work with AI development tools such as Langfuse, OpenAI, Claude, Cursor, and Codex to move faster and build smarter.
I'm deeply excited by the potential of AI as a productivity multiplier and as a way to scale impact in education and beyond. In the last year, I've contributed nearly 5,000 commits and thousands of lines of production code while collaborating closely with product and design teams. I enjoy taking full ownership of features, iterating quickly from user feedback, and spending my free time building side projects and sharpening my system design skills.
