Capabilities

Dashboards and analysis first, then the engineering that supports the data work and keeps it running. Written from what I have shipped, not what I have read about.

$ cat stack.json

Tech stack

The tools the work actually runs on. Analysis on top, dashboards and documentation in the middle, what ships at the bottom.

$ ls ./projects

Projects

Eight projects, with what each one actually produced.

EGACE status dashboard

Dashboard

A recurring Excel dashboard tracking every scholarship trainee through the five EGACE stages — Enrolled, Graduated, Assessed, Certified, Employed — built on lookups against the trainee records so the counts update from one source rather than being tallied by hand.

→ One place to see where a batch stands, instead of five separate counts.

Agentic CI/CD workflow

DevOps

A GitHub Skills challenge completed end to end: an agentic GitHub Actions workflow authored in markdown and compiled to a .lock.yml pipeline. Runs on a daily schedule or on demand with read-only permissions, fetches sources over an explicit network allowlist, keeps its credentials in repository secrets, and returns its change as a draft pull request instead of pushing to main.

→ Triggers, least privilege, secrets and a human review gate.

linear-git-skills

Workflow

Two custom Claude Code skills that automate the branch-to-PR loop for teams using Linear with the GitHub integration. Linear links a branch to an issue only by matching the branch name it would have generated itself, so create-feature-branch reproduces that format exactly rather than re-implementing the slug, and create-pr runs the project's checks, summarizes the real diff, and updates an open PR instead of failing on one.

→ Read-only against Linear, so a two-way sync can't produce duplicate issues.

Dengue Outbreak Forecasting Dataset & Model

Published

A monthly 2015–2024 dataset for SOCCSKSARGEN, reconciled from DOH-CHD case records, Google Earth Engine rasters and NAMRIA shapefiles, and the forecasting model built on it.

→ 2,918 rows × 19 columns from three incompatible source types. First author of four.

Screenshot of the research pipeline in Claude

AI research & verification pipeline

Process

A repeatable pipeline built in Claude: topic and niche validation, source gathering, automated scraping with Firecrawl, claim verification against official documentation and peer-reviewed sources, then an editorial pass for voice and consistency.

→ Ran on every article, so the process stayed auditable and each claim traceable.

Skill output landing in Google Docs

medium-draft, a custom Claude skill

Tooling

A Claude skill that outputs publication-ready drafts directly into Google Docs, so research and publishing meet without a manual reformatting step in between.

→ Removed the reformatting step entirely.

Transaction tracking mobile app

Internship

Built at LEADSolutions INC as an on-the-job trainee: a Flutter mobile application for transaction tracking, integrated with the company's existing web system on Azure Cloud so data moved between the two without manual re-entry.

→ Designed the UI/UX as well as the build, from navigation through to cloud integration.

Records or compliance documentation (redacted)

TESDA scholarship records, end to end

Ongoing

Trainee, programme and scholarship records encoded into T2MIS, TESDA’s national training management information system, plus the compliance documentation behind them and the billing reconciled against government purchase orders.

→ Three vocational programmes kept audit-ready for four years running.

Writing, and the gate before it

Long-form technical articles on AI and software engineering, 1,200 to 2,500 words, for professional audiences on Medium and LinkedIn. Every one of them went through these five steps.

1. 01

   Topic and niche validation

   Is there an audience, and is there anything new to say to them.

2. 02

   Source gathering

   Government, academic and technical documentation first, commentary second.

3. 03

   Automated scraping

   Firecrawl pulls the sources so the reading list is complete before drafting.

4. 04

   Claim verification

   Every technical claim checked against primary sources. Nothing publishes on trust.

5. 05

   Editorial pass

   Voice and consistency, plus diagrams so verified facts read at a glance.
