Building Complex Systems. Refining ideas.
I build software end-to-end — resilient, considered, quietly complex. From cross-platform mobile apps to browser automation and the APIs that bind them. The best systems disappear: rigorous logic underneath, a human experience on top.
Tangled systems, made to feel simple. I sweat the details no one sees — so the surface always stays effortless.
Curious by Nature,
Precise by Design
I'm Raniel Art N. Montebon — a full-stack software engineer from Davao City who ships production web platforms and automation systems end-to-end. I build with React, Next.js & TypeScript on the front and .NET, NestJS & FastAPI on the back — with a real specialty in Playwright browser automation and large-scale scraping. Across two internships and three startups, I've shipped products real people use, and mentored 200+ students along the way.
Every architecture, whether built in syntax or carved into stanzas, is just an attempt to give lasting form to the invisible. We build the frameworks so the current has a place to flow, rather than simply spilling out into the void.

FarmIQ · MooManage · STRUKTURA & more — view all →
Production platforms built end-to-end — from a solo-architected .NET 9 + React Native farm system to a Play Store-shipped dairy app and a construction marketplace.
- FarmIQ — solo full-stack platform on Clean Architecture, CQRS & a 149-test suite, serving 5 roles from one codebase.
- MooManage — shipped to Google Play as CTO; 40% faster components and a security fix that closed a fail-open auth flaw.
- STRUKTURA — co-architected construction marketplace on NestJS, Prisma, Redis & BullMQ with escrow at its core.
- Six case studies spanning mobile, web, marketplaces, serverless delivery & a hand-rolled PHP MVC.
Deepfake Audio Detection
AP-CQCC LSTM · Feature Fusion Thesis
An LSTM that detects AI-generated voices by fusing acoustic-prosodic and CQCC spectral features — with a controlled ablation proving the gain came from fusion, not a bigger network.
- Cut Equal Error Rate from 27.37% to 24.32% and lifted AUROC to 0.836 on held-out ASVspoof 2021 data.
- Ablation showed 1.89 of 3.05 points of gain came from the feature fusion itself.
- Improved bonafide recall by 7.2 pp — far fewer real speakers wrongly flagged.
Good engineering is a kind of poetry — structure that carries meaning. I build systems that hold their complexity quietly, so the people who use them only ever feel the simplicity.
Experience
Inventiv
Architected an Electron-based B2B SaaS platform end-to-end with Playwright + Camoufox automation for large-scale scraping and live API interception. Shipped cross-platform CI/CD building .exe / .dmg / .AppImage artifacts; cut metrics latency with a Cron polling layer + Redis caching.
