ABOUT
Hi, I'm Yatinj.
I'm a founder and full-stack engineer focused on building software systems that solve real operational and product problems.
My background spans web and mobile development, backend systems, payments, cloud infrastructure, AI, and workflow automation. That allows me to work beyond one layer of a product and understand how the complete system needs to fit together.
Over the years, I've worked with startups, founders, marketplaces, SaaS platforms, and established businesses on everything from Stripe payment architecture and full-stack applications to AI integrations and automated business workflows.
Today, much of my work sits at the intersection of software engineering, AI, payments, and automation - especially where businesses need custom engineering beyond what standard tools can provide.

AI-assisted engineering
Systems over isolated features.
Stripe
Not just checkout - Connect, commissions, webhooks, subscriptions, ACH, and production payment lifecycle design.
AI
Not demos - agents, tool calling, RAG, approvals, and AI features wired into real product workflows.
Next.js
Not pages alone - full-stack products with APIs, auth, data models, and deployment readiness.
Automation
Not only no-code - n8n/Make/Zapier plus custom APIs, databases, and failure handling when platforms hit limits.
