Nina Valdez

I’m a full-stack and mobile developer with 4 years of experience building deployed apps, backend systems, and ML-enabled IoT pipelines. I enjoy turning complex requirements into reliable, user-focused products—from core UI/UX to production-ready services.

In my Capstone, I architected a scheduling system that supports multi-perspective views (by room, time, instructor) with full CRUD, with all operations persisted via Supabase. I collaborated with a team of 3 using Git workflows and reduced scheduling preparation time by 50% by automating conflict detection and timetable generation.

I’ve also shipped backend APIs and ML-enabled IoT features, designing a custom lightweight routing protocol for multi-node LoRa communication and building FastAPI APIs for ingestion, processing, and alerting. From a cybersecurity internship, I built Python/VBA automation to streamline security workflows (reducing manual review time by 4 hours per week), and I’ve launched Flutter apps with real-time sync and monetization tooling, managing a user base of 1,000+ installs during an active lifecycle.
