What I'm looking for

I’m looking for a role where I can build and own scalable products end-to-end—combining strong backend engineering with AI integrations—while collaborating in a fast, remote-friendly environment and delivering measurable customer impact.

I’m a builder at heart: I create AI-powered full stack, responsive applications with real-time updates. Recently, I built an AI-powered language learning experience and designed AI agent workflows that deliver intelligent, context-aware exercises.

In my recent engineering work, I scaled B2C email notification infrastructure for B2B partners by decoupling partner configuration from core logic—reducing onboarding from weeks to hours and improving launch velocity 5-10x. I also automated B2B email review workflows, cutting manual effort from 2-3 hours to minutes.

As a Sr. Software Engineer at Groove (a Clari Company), I owned end-to-end development and stability for the Dialer application. I led critical features like Voicemail Box and International Local Dial using Ruby on Rails, S3, Twilio, ReactJS, Apex, and ElectronJS—supporting retention of high ARR customers.

Earlier, as Lead Software Engineer at VueOps Payroll, I led mission-critical modules (VueOps Drive and File Processing Engine), supported hiring and mentoring, and helped the system scale reliably under load. I also built internal tools and backend systems across multiple startups, with a strong focus on stability, performance, and measurable cost and failure reductions.
