Hi, I’m Evan Czako, a Full-Stack Software Engineer who builds scalable UIs, services, and data-driven systems. I enjoy turning complex requirements into clean, modular frontend and robust backend implementations using React, TypeScript, Node, and SQL while collaborating closely with backend teams to optimize API contracts and data flows. In roles at Bloomberg and ASML, I pair hands-on development with mentorship, performance-minded thinking, and a passion for maintainable architectures. I also pursue side projects like ChordFinder and DoughLoops to explore interactive UI design and audio-data workflows, continually learning and sharing best practices with my teammates.…Hi, I’m Evan Czako, a Full-Stack Software Engineer who builds scalable UIs, services, and data-driven systems.

Work Experience

Senior Software Engineer at Bloomberg LP

August 1, 2025 - August 1, 2025

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

Optical Process Engineer at ASML

April 1, 2021 - April 1, 2021

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.
