About Mayank Sharma
Software Engineer with 3+ years of experience building scalable, high-performance applications across backend and full-stack environments. I specialize in designing reliable systems using Node.js, TypeScript, and AWS, with a strong focus on microservices architecture, API development, and data-driven solutions. In my recent role, I’ve worked on production systems handling 10K+ monthly transactions with 99.9% uptime, optimized database performance to reduce response time by 60%+, and built integrations with major platforms like Amazon, eBay, and logistics providers. I enjoy solving complex engineering problems, improving system reliability, and delivering efficient, maintainable solutions. My core expertise includes: • Backend Development: Node.js, Express, NestJS, REST APIs, Microservices • Frontend: React, Next.js • Cloud & DevOps: AWS (Lambda, S3, RDS), Docker, Terraform, CI/CD • Databases: PostgreSQL, Redis (performance tuning, indexing, caching) I thrive in fast-paced, collaborative environments and bring a strong foundation in system design, data structures, and scalable architecture. Currently open to Software Engineer / Backend / Full Stack opportunities in the USA.
