What I'm looking for

I seek backend roles building scalable SaaS and AI-driven systems, with opportunities for technical ownership, integrations, and production-grade reliability.

I am a software engineer with 6.5+ years of backend experience focused on building scalable SaaS platforms and high-performance APIs. I specialize in Ruby on Rails and have strong experience with distributed backend architectures and background job systems.

I design and implement REST APIs, marketplace systems, payment integrations, and automation workflows, and I maintain production applications on cloud infrastructure. My technical work routinely uses PostgreSQL, Redis, Sidekiq, and various cloud platforms.

I have delivered AI-driven backend solutions including RAG pipelines, voice agents, and automation workflows using LangChain, LangGraph, and LLM APIs, plus integrations with Stripe, Twilio, and third-party SaaS tools. Notable projects include patient onboarding and voice AI for healthcare, lesson-booking marketplaces with Stripe payouts, and clinic lead-management systems with marketing automation.

I prioritize reliable, observable systems and measurable performance improvements, applying tools such as New Relic, Sentry, and CI/CD pipelines to keep production services resilient and performant.
