Build the interface
React and vanilla JavaScript front ends with semantic HTML, responsive CSS, and states that hold up on a phone as well as a laptop.

Kerneil Rommel S. Gocotano
Web & Software Developer / QA Analyst / React, Django & Node.js
I build web applications end to end and test them before anyone else has to. React and JavaScript on the front, Node.js and Django behind it — plus two years of hands-on QA on a licensing platform that real users depend on every day.

/what-i-do
Build it, wire it, then try to break it
Three jobs, one workflow. The last one is the part most developers hand to somebody else — I've been doing it on my own platform for two years.
Wire up the backend
RESTful APIs and relational schemas in Node.js, Django, and Laravel — authentication, role-based access, and the data model underneath all three.

Test it before release
Every PandaAuth release goes through a manual API pass: request cases in Postman, edge cases with curl, traffic inspected and replayed in Fiddler.

Selected work
Four builds with real users behind them — two running in production I maintain myself, two from my internship.
PandaAuth Key System Service
2022 — Present
Authentication and licensing platform handling registration, license validation, and entitlement checks for real users. I built the API layer, run the QA pass on every release, and manage the Linux/Nginx VPS it runs on.
- Token-based authentication and license validation APIs
- Manual API regression suite in Postman, traffic analysis in Fiddler
- Self-hosted deployment with reverse proxy and uptime monitoring

Clinic Web Application
2025 — 2026
Healthcare platform for patient records, appointments, and clinical workflows. I rebuilt the backend around REST APIs and a PostgreSQL schema, then added AI-assisted documentation tools clinicians use during consultations.
- REST APIs and PostgreSQL schema for records and appointments
- LLM-generated patient notes and real-time speech-to-text transcription
- Encrypted auth, role-based access, HTTPS-enforced data handling

Multilingual Speech-to-Text
2026
Django transcription service tuned for Philippine languages — Cebuano, Tagalog, and English, including code-switched Taglish and Bislish in the same sentence. Handles file uploads and live microphone input, returning word- and segment-level timestamps with confidence scores.
- Whisper Large-v3 pipeline with automatic per-segment language detection
- Real-time transcription over Django Channels WebSockets
- Audio preprocessing and noise reduction across WAV, MP3, FLAC, M4A, OGG, and WebM
- REST API plus JSON, TXT, SRT, and VTT export, with custom vocabulary for local terms

PandaBlox
2026
Server-rendered platform where users publish, browse, search, and moderate Roblox Lua scripts. Runs in production at blox.pandadevelopment.net, with the source released under GPL-3.0.
- JWT and bcrypt authentication, plus PandaAuth and Google OAuth sign-in
- Script publishing with tagging, thumbnails, full-text search, and view tracking
- Moderation dashboard with audit logs and an HMAC-SHA256 signed publish API
- Redis caching and rate limiting, Helmet CSP, input sanitization, Docker deployment

Where I've worked
Full-Stack Developer & QA Analyst
August 2022 — PresentPandaAuth Key System Service
- Architected and deployed a full-stack authentication and licensing platform serving real users — registration, license validation, and entitlement checks over Node.js REST APIs.
- Own QA for the platform: write and run API test passes in Postman, probe edge cases and malformed payloads with curl, and inspect, replay, and tamper-test live traffic in Fiddler before every release.
- Designed token-based auth and automated license validation that form the core of the entitlement-checking pipeline.
- Self-manage the Linux/Nginx VPS end to end — security updates, reverse proxy configuration, and uptime monitoring.
