Also delivered a Webflow CMS-driven Capoeira site (dynamic events/profiles) and shipped updates iteratively under tight timelines with strong QA and accessibility practices.”

“Frontend engineer who helped build a desktop-as-a-service product from scratch and has delivered complex React + TypeScript workflows (including multi-stage approvals). Notable for performance-focused refactoring (removing unnecessary memoization), building reusable component patterns, and leading a major shift from hard-coded forms to a configurable form-builder with strong dev/QA collaboration and heavy scenario testing.”

“Frontend engineer who led the Cariveco frontend end-to-end, establishing a scalable React/TypeScript architecture with a design system, CI-driven quality gates, and strong performance practices (Lighthouse, code-splitting, caching). Experienced building complex dashboards with role-based views and real-time data using Redux + RTK Query, and shipping major features quickly with automated testing, feature flags, and Sentry monitoring.”

“Frontend engineer who led end-to-end delivery of an HR Service Desk (HRSD) module used daily by HR teams, setting a modular React architecture with standardized data access and shared component libraries. Focused on scaling and performance (lazy loading, memoization, pagination, normalized state) and enforced quality via unit testing, strict code reviews, ESLint, and TypeScript.”

“Frontend engineer with digital banking experience who led end-to-end development of a React/Next.js dashboard and later shipped a major digital-signature feature under tight deadlines. Emphasizes scalable architecture and team-wide quality practices (Husky/ESLint/Prettier, code reviews), plus pragmatic state/data tooling (Zustand + React Query) and controlled rollouts via feature flags.”

“QA tester based in Egypt with experience across web/mobile/app testing plus SQL/database, API, and performance testing. Interested in transitioning into console game testing (PlayStation/Xbox/Nintendo) despite no direct TRC/XR/LOT experience, and has used ChatGPT to quickly upskill and convert automation from Puppeteer to Playwright using a Page Object Model.”

“Unity/C# gameplay programmer with professional experience at Fabwelt Studios on the play-to-earn title "Arsenal," implementing player mechanics, interaction systems, and event-driven gameplay features. Also built a research-focused Tetris prototype as a master’s thesis, adding seedable RNG controls, data logging, and a playtest harness to study how randomness affects player perception.”

“3D artist from a live marketing agency in São Paulo who shipped VR/AR/MR brand experiences, including a Meta Quest tennis experience for FILA and a mixed reality perfume feature demo for Natura. Creates user-comfort-focused VR feedback VFX and can prototype interaction checks in-engine using ChatGPT-assisted coding before handing off to engineering.”

“Robotics lead engineer (PhD/agriculture research context) who built and iterated a three-unit, wirelessly coordinated greenhouse data-collection robot—solving real-world alignment and comms reliability issues by redesigning the rail/gear system and moving from RF to ESP Wi-Fi with MAC-addressed control. Strong embedded C/C++ background with full-stack robot control implemented from scratch; beginning exposure to ROS 2 via an upcoming field deployment.”

“Marketing/brand designer with portfolio work spanning luxury cosmetics social creative and a Figma-designed website (Shea Organics), plus reusable brand kit templates.

“Unity developer with hands-on Meta Quest XR experience building a radiography/X-ray training proof-of-concept and deep expertise in performance and large-world optimization. Built a bus simulator largely solo, implementing modular vehicle systems, localized traffic AI, multiplayer, and low-end device optimizations. Also develops internal AI tooling (auto-documentation and an AI UI generator) to speed up prototyping and reduce boilerplate.”

“Unity/Meta Quest VR developer focused on training simulations and digital twins across defence, construction, real estate, factory, and education. Built a factory VR twin by reconstructing spaces from photos/dimensions and iterating on interactivity, and also delivered a client-driven VR horror game end-to-end using a full GDD/gameflow process.
