Contributed to migrating a legacy healthcare platform from server-rendered PHP to React, introducing API-driven workflows and establishing consistent behavior across devices.
- Built React interfaces for admin dashboards, patient records and medication workflows.
- Implemented GraphQL queries and mutations for form submission, validation and pagination.
- Developed reusable form patterns and layout primitives for large, mobile-constrained workflows.
- Ported legacy PHP screens to React while maintaining parallel old and new interfaces.
Stack: React, TypeScript, GraphQL, Styled Components
Mobile Developer

Jan 2023 - Sep 2023
Worked on mobile banking applications from initial development to release, covering core financial workflows under production constraints.
- Built React Native interfaces across account management, transfers, payments and debit card features.
- Integrated REST APIs handling authentication, request mapping, pagination and error states.
- Improved flow modularity and shared component structure to reduce duplication across screens.
- Participated in App Store and Google Play release processes.
Stack: React Native, TypeScript, REST APIs
Software Engineer
INOV
Mar 2021 - Feb 2022
Worked on applied computer vision research for infrared-based object detection and classification in surveillance systems.
- Built an infrared-based detection system for identifying people, vehicles and deer.
- Collected, labeled and curated datasets, including organizing on-site data acquisition.
- Trained and evaluated models using TensorFlow and supported deployment into a C# inference application using OpenCV.
Stack: Python, TensorFlow, CUDA, OpenCV, Computer Vision
Projects
Designed and built a production-level mobile application covering the full workout lifecycle from setup to execution and tracking.
- Cross-platform mobile architecture with React Native and Expo Router enabling fast iteration and consistent behavior.
- State-based timer system with a 1Hz update cycle ensuring predictable execution under runtime constraints.
- UI-thread animations with React Reanimated avoiding JavaScript thread blocking.
Stack: React Native, Expo Router, React Reanimated, TypeScript
Designed and built a portfolio platform for presenting projects, documentation and a developer profile.
- Next.js App Router architecture with server-rendered pages for landing, project and documentation flows.
- Motion-driven UI using Framer Motion for layout transitions and content sequencing across the platform.
- Multi-surface structure combining projects, documentation and profile content within a single application.
Stack: Next.js, TypeScript, App Router, CSS Modules
