Developed and modernized internal microfrontend applications using TypeScript and a React-inspired declarative framework, while designing and integrating RESTful service endpoints consumed by the UI. Built dynamic, data-driven cashflow projection tools for mortgage-backed securities, orchestrating data retrieval, validation, and transformation across multiple internal services and models. Collaborated with backend teams to shape API contracts, optimize service payloads, and improve request performance, resulting in faster chart rendering and reduced over-fetching. Ensured reliability and maintainability through Jest unit tests and Cucumber end-to-end workflows. Contributed to the design and implementation of a signal-based reactive framework used across multiple microfrontends, improving data-flow performance while simplifying application architecture. Mentored engineers on best practices for building modular full-stack features using internal frameworks, promoting clean separation of

Wrote MATLAB programs and VBA macros to automate and accelerate the review of optical metrology data for both commercial and non-commercial modules. Compiled an executable MATLAB program allowing spindle polishing technicians to evaluate the surface figure error of optics in their workcenter, minimizing rework and saving several hours of processing time per optic. Scripted a new method of filtering surface figure data to improve compatibility with CNC MRF machines and increase the likelihood of successful MRF polishing runs. Facilitated PFMEA for optical metrology to identify and mitigate potential process risks.
