Piyush Singh

I am a full-stack engineer and engineering leader with 12+ years of hands-on experience building, scaling, and operating high-impact digital products across fintech, Web3, SaaS, and consumer platforms. My background combines deep technical execution with system-level thinking, enabling me to deliver reliable, scalable, and revenue-driven solutions.

On the backend, I have extensive experience designing and developing APIs and core systems using Python (FastAPI, Django) and Node.js.

On the frontend, I have worked with React and Next.js to build dashboards, consumer-facing applications, and admin platforms.

I have strong experience deploying and operating systems on AWS, including architecture design, CI/CD pipelines, monitoring, scaling, and cost optimization. I have worked with cloud-native setups using EC2, containerized services, RDS, and object storage, ensuring high availability and operational stability. I hold the AWS Certified Solutions Architect – Professional certification, reflecting deep practical knowledge of cloud infrastructure.

Database design and optimization are a core strength. I have worked extensively with PostgreSQL, handling schema design, indexing strategies, query optimization, and performance tuning for large datasets. I have resolved real-world issues such as slow queries, N+1 problems, transaction bottlenecks, and data consistency under load.

Beyond individual contributions, I have led and mentored teams of up to 50+ engineers, scaled organizations from zero to maturity, and delivered 100+ SaaS/PaaS solutions globally. I have taken multiple products from zero to one and scaled platforms to 500K+ users, driving multi-million-dollar revenue growth.

Overall, I bring a balanced combination of hands-on engineering, architectural rigor, and execution discipline, with a strong bias toward building systems that perform reliably at scale and deliver measurable business impact.
