What I'm looking for

I'm looking to own frontend architecture and build high-performance, data-dense products, while setting engineering standards, mentoring teams, and applying AI-native workflows in fintech or capital-markets environments.

I've built and maintained React interfaces for Numerix Market Risk products serving US capital markets clients, including AG-Grid-driven screens for large risk datasets and a migration from a legacy monorepo to micro-frontends using Webpack Module Federation.

Previously at Tazapay, I shipped scalable Vue and React features for B2B escrow payments, built and published a Shopify Payments app, and led a frontend team of 4–6 engineers through code review and mentorship. At TCS, I solely delivered a globally deployed React Payment Status Search UI for an international bank and built treasury UI flows for hedges and deposits.
