I build production backend systems, AI platforms, and event-driven workflows with Ruby on Rails.

Message

I've built agentic AI and backend platforms at Sourcefuse Technologies, including a Ruby on Rails system that turns client requirements into approved solution blueprints and provisions cloud infrastructure through AWS Bedrock, Bedrock AgentCore, Mastra, RAG, and pgvector.

I also unified tenant onboarding, lease processing, invoicing, reminders, agreements, and rewards into OneFlow, replacing manual workflows with a Rails, Node.js, and N8N platform. Previously at Foxy, I built a public Shopify app for merchant onboarding and catalog integrations, plus a personalized product discovery feed for its grooming and beauty e-commerce app.

At PlanetSpark and CaratLane, I've delivered secure video-auditing, CRM, real-time support chat, order-to-invoice automation, and AWS Lambda microservices. I focus on dependable multi-tenant systems, event-driven workflows, and practical automation that moves work from days to hours.
