Crafting Intelligent
Hi, I'm Noel Niño Olvis. I'm a Full-Stack Software Engineer based in Pasay City, Philippines, specializing in AI integration & automation, multi-tenant security, and scalable systems. Currently exploring advanced RAG architectures and building reliable web platforms.
About Me
Full-Stack Software Engineer — AI Integration & Automation
I'm a full-stack software engineer based in Cebu and/or Pasay City, Philippines, focused on building intelligent, reliable web applications. I specialize in AI integration & automation, engineering Retrieval-Augmented Generation (RAG) pipelines, and architecting scalable backends.
Personally, I prioritize long-form technical literature because it provides the architectural context that blog posts and videos often skip. As mentioned by one of the honorable scholars, "Books to me are better than the palaces of kings."
Intelligent Systems & RAG
LLM APIs, RAG. Engineered custom pipelines using vector embeddings and prompt orchestration to parse documents, ground responses, and minimize hallucinations.
Full-Stack Integration & BaaS
Next.js, Supabase, Firebase. Integrated cloud-native backends for secure authentication, real-time data sync, and serverless storage.
Cross-Platform Client Engineering
React Native (Expo), TypeScript, Tailwind CSS. Built unified, responsive component architectures for web and mobile with robust state management and type-safe data fetching.
API & Service Orchestration
Node.js, REST APIs, AWS Lambda. Integrated third-party services and managed lightweight, event-driven backend logic to securely route data.
Technical Arsenal
Languages, frameworks, and tooling categorized by focus.
Frontend & Mobile

Full-Stack Developer
Pundasyon PH
- Built a 3-sided B2B marketplace within a Turborepo monorepo, scaling the Next.js App Router frontend — proactively refactored a 1,000+ line server actions file into 4 Domain-Driven Design (DDD) packages, enforcing SRP and reducing codebase coupling by ~40%
- Engineered an offline-first CQRS milestone tracker (IndexedDB + TanStack Query) guaranteeing 99.9% remote resilience — designed PostgreSQL/PostGIS spatial schemas executing k-NN queries to drive routing latency to <50ms and power a dynamic fleet Turnaround Time (TAT) algorithm
- Automated an escrow handshake mechanism via the PayMongo API and an immutable double-entry financial ledger — securing distance-based freight calculations and triggering zero-drift payout splits immediately upon customer-verified delivery RPC calls
- Secured multi-tenant data access by shipping Supabase RLS policies and custom RPCs with `FOR UPDATE` locks to eliminate 100% of broadcast race conditions — root-caused and patched mass-assignment vulnerabilities using explicit relational checks and Zod boundary validation
- Engineered a hybrid mapping architecture utilizing the free Photon API for geocoding and reserving the paid Google Maps Routes API exclusively for final truck distance validation, reducing map-related API costs by >95%
