Mayank Awasthi
Senior Full-Stack Engineer | React, TypeScript, Node.js | SaaS & Cloud
I’m a Senior Full-Stack Engineer with 13+ years of hands-on experience building production web applications, SaaS platforms, APIs, and cloud-based systems.
My core stack includes JavaScript, React, TypeScript, Node.js, PostgreSQL, REST APIs, and AWS. I work across the full product lifecycle—from understanding requirements and designing solutions to development, testing, deployment, and production support.
I’ve worked on eCommerce, OTT, marketplace, business, and data-driven applications, with a strong focus on scalable architecture, performance, API integrations, reliability, and maintainable code.
I’m particularly comfortable joining an existing product or codebase, understanding the architecture quickly, and taking ownership of features from requirements through production. I enjoy solving practical engineering problems and working closely with product and engineering teams to deliver reliable solutions.
I also have experience with AI/LLM integrations and modern application architectures, and I’m comfortable working across frontend, backend, APIs, databases, and cloud infrastructure.
I’m looking for long-term opportunities where I can contribute as a hands-on senior engineer, take ownership of meaningful technical challenges, and help build products that are reliable and scalable.
