Experience

Optimized the smart assistant: end-to-end analysis, spotted a data-architecture issue and migrated from a relational database to a vector database (Milvus) — response time cut in half. Built role and access management for external providers, technical screens, and documentation adopted as an internal reference.

Complete interface redesign in Figma and creation of the visual identity. Ran research and usability tests to align the design with real needs, simplified the user flow, and improved accessibility.

Within the Sales R&D team: maintenance and new features on the loyalty module (order-wide discounts, loyalty in the portal, bug fixes). Every change was validated by tests (unit, integration, UI) before going to production.

Collected and structured data (web scraping, APIs) with a maintainable class system. Extended a REST API to automate imports from Dropbox. Rebuilt the Twitter streaming API on v2 (multiprocessing, async requests, parallel keys) to fetch tweets in real time at scale.

Built several pages (contact, referral, leaderboard, partner stores, onboarding) for a donation app. Refactored code and data, with UI/UX contributions mostly adopted and full ownership of some pages.

Supported and mentored students in project-based learning: helping them grasp technical concepts, hands-on demonstrations (data structures in C), debugging complex problems, running activities, and grading projects.
