Get to Know Me

About

Shreyansh Singh

I'm a full-stack developer who's spent the last 3+ years building production SaaS applications — from statistical dashboards and CRM systems to complex automation pipelines.

At Portfolio Play, I was the core developer behind Atlas SalesOS, a multi-tenant sales intelligence platform used by B2B companies across Europe. I built everything from the Next.js frontend to the Supabase backend, designed the role-based access system, and wired up integrations with Smartlead, Cloudtalk, and custom automation workflows using Make.com and n8n.

Before that, I worked at BlogVault — a WordPress backup platform trusted by 400,000+ websites — where I optimized server performance by 40%, revamped 150+ API routes, and built tools that handled millions of backups.

I write efficient, well-tested code. My background in competitive programming (top 7.6% on LeetCode, 1,100+ problems solved) means I approach every technical challenge with algorithmic precision.

When I'm not coding, I'm exploring the cutting edge of AI — from building production AI features to experimenting with generative tools. I believe the best developers are the ones who never stop being curious.

Technologies I work with:
