Professional summary

Junior Software Engineer with a strong Computer Engineering foundation, system-level problem solving, and hands-on full-stack development experience. Proven track record in architecting high-efficiency APIs, relational database schemas, and AI-integrated systems using Python, TypeScript, and C++, with a passion for robust software architecture and automated workflows.

Experience

Q Asia Magazine Inc.

Information Technology Intern · Mandaluyong City

  • Developed an automated email outreach application using Python, CustomTkinter, and FastAPI, streamlining bulk client campaigns and saving 4 hours of manual work per session.
  • Programmed dynamic data parsing engines to handle Excel and CSV recipient databases, automatically generating tailored HTML invitation templates for up to 150 businesses at a time.
  • Integrated security controls and batch throttling to prevent spam flags, alongside an interactive browser-based previewer, successfully increasing overall outreach efficiency by 60%.

Technical projects

AniVerse

Anime Discovery and Streaming Platform

  • Built and deployed a full-stack anime discovery web app using Next.js, TypeScript, FastAPI (Python), and MongoDB on Vercel.
  • Aggregated metadata for over 27,000+ anime entries by integrating AniList (GraphQL) and Jikan/MAL APIs, normalising disjointed data sources into a unified, indexed schema to reduce search latency.
  • Enhanced backend stability by isolating scraping procedures into asynchronous subprocess jobs and implementing custom caching and merge logic to handle external API rate limits seamlessly.

Vitae

AI Resume Builder

  • Developed a production-grade resume builder using Next.js (App Router), TypeScript, and Prisma ORM, implementing Supabase authentication and real-time auto-save versioning on a PostgreSQL database.
  • Shipped 4 distinct AI features (rewrite, ATS scoring, job-match, cover letters) using a dual-provider architecture (Groq + OpenRouter) to ensure 100% uptime and reliability during LLM API outages.
  • Secured application endpoints by engineering Upstash token-bucket rate limiting, input sanitization pipelines, and strict authorization guardrails against prompt-injection vulnerabilities.

GhostProject

ML Flood Infrastructure Planning Platform

  • Developed a responsive full-stack web application using Next.js (App Router) and TypeScript, leveraging React Server Components (RSC) to optimize data fetching for downstream ML model predictions.
  • Built an interactive geospatial dashboard utilizing React-Leaflet and Tailwind CSS to seamlessly cluster, color-code, and render 9,855 nationwide data points flagged by an XGBoost risk classification engine.
  • Integrated asynchronous REST APIs using FastAPI and Python 3.11 to link the user interface with an in-memory DuckDB database, achieving sub-second model inference responses for predictive budget queries.
