Application architecture and engineering delivery across enterprise payments and banking: shared monorepo foundations, performance, security, technical reviews, and mentoring.
Explore responsibilities +
- Shape application structure and reusable engineering patterns across enterprise products, translating business requirements into maintainable implementation decisions.
- Build with React, TypeScript, Next.js, reusable component patterns, shared libraries, modern state/data tooling, and monorepo workflows.
- Coordinate with product, design, QA, backend, architecture, and DevOps partners to clarify requirements, manage dependencies, and carry features through review, release, and production support.
- Review technical approaches and code for module boundaries, reuse, state and API flows, performance, accessibility, security, and long-term maintainability.
- Support Agile delivery through estimation, sprint execution, defect resolution, production fixes, release coordination, and continuous improvement.
- Use AI-assisted engineering tools including Claude Code, GitHub Copilot, Gemini, and ChatGPT for exploration, debugging, refactoring, documentation, tests, and prototyping while keeping architecture and release decisions human-reviewed.
- Mentor and support other developers through code review, reusable patterns, debugging guidance, and engineering best-practice discussions.

Citi
Data-rich financial interfaces where feature delivery, state management, rendering efficiency, and load performance were central engineering concerns.
- Delivered 20+ frontend features using React, TypeScript, and Next.js across financial application journeys.
- Built dashboards, graphs, and interactive data experiences while keeping reusable UI patterns consistent across the product.
- Implemented Redux Toolkit and React Query patterns that reduced unnecessary re-renders by 35% and improved data-flow efficiency.
- Improved reported page load performance by 40% through code splitting, lazy loading, and frontend optimization.
- Worked with OWASP-aligned security practices and engineering quality checks during development and review.
- Delivered in two-week Agile sprints with 90% on-time delivery across the engagement.
- Mentored 3 junior developers, performed code reviews, and helped build reusable component patterns for the team.
