I build production SaaS features across React, Node.js, payments, automation, and AI workflows.

At Venture Miner, I build production SaaS features end to end across React, Next.js, Node.js, NestJS, Prisma, and PostgreSQL.

I've reduced feature-delivery time by roughly 25% by delivering interfaces, APIs, authentication, permissions, schema changes, and external integrations. I also built a secure document pipeline with browser encryption, S3 uploads, integrity checks, and context-bound sessions that reduced invalid-document retries by roughly 30%.

I implemented Stripe and TazWorks screening flows covering checkout, off-session payments, consent gates, webhooks, reconciliation, and idempotent refunds. I've also built AI-assisted property imports and conversational commerce across web chat, WhatsApp, SMS, and email with Shopify context and human handoff.

Earlier at Venture Miner, I shipped 20+ production screens and reusable components, and cut campaign setup and mailbox follow-up time by approximately 40% through event-driven email processing. I work comfortably across frontend, backend, integrations, testing, and delivery automation.
