What I'm looking for

I’m looking to build scalable B2B products with modern web architecture and measurable impact—shipping full-stack features, strengthening engineering standards, and delivering AI-powered experiences (e.g., LLM/RAG workflows) with strong performance and developer experience.

I’m a Software Engineer with 2.6+ years of experience building scalable B2B SaaS platforms and AI-powered applications. I focus on performance, scalability, and developer experience, and I’ve supported products exceeding $1M ARR.

At Zintlr Pvt. Ltd., I’ve owned end-to-end platform work—from architecture through full-stack delivery. I was promoted twice in 18 months for consistently delivering high-impact features, modernizing platform architecture, and improving engineering standards.

I built a centralized notification system end-to-end, unifying fragmented alerts into a single service and delivering notifications to over 95% of active users. I also developed an AI-powered Zoho SalesIQ conversational layer trained on a custom knowledge base, integrating Teams/Calendly and automating 80% of inbound queries.

I’ve led modernization efforts such as the App Router migration, rolling out a Playwright + Vitest strategy reaching 85%+ coverage. I’ve also engineered core product capabilities like Stripe and Razorpay billing integrations and improved operational efficiency by 90% through scalable RBAC workflows, while reducing Docker image size by 60%.
