Engineering rigor. Data clarity. Reliable execution.
I am Kerwin Dio Joseph Arlan, a continuing Civil Engineering student at UP Diliman. I automate PAGASA cyclone tracking, calibrate storm-surge models for Manila Bay, and bring hands-on data analysis, AI data operations, and construction quality control to every team I join.
Evidence over buzzwords.
A cross-disciplinary background built through real operational work, technical quality checks, direct client interaction, and long-term teaching.
Operational analysis
Analyzed operational data using Excel and CRM tools, performed database quality checks, and produced weekly performance dashboards.
ML data readiness
Prepared, cleaned, validated, annotated, and audited datasets while helping refine annotation protocols with data engineers.
Construction quality
Supported site engineering work and supervised quality control for finishes on a five-storey school building.
Teaching and support
Built customized learning plans over several years and handled complex customer billing and service escalations.
A non-linear path with a consistent pattern.
Each role strengthened the same core habits: investigate carefully, communicate clearly, document the work, and improve the process.
JAN 2026
Junior Data Analyst
Swinnerton-Staten Solutions, Inc.- Extracted and analyzed operational data from CRM systems and client databases, building repeatable analyses in Excel.
- Performed structured data-quality audits on client databases, catching inconsistencies before data reached reporting and decision-making.
- Built weekly performance dashboards and reports that directly informed operational and strategic decisions.
- Worked with cross-functional teams to streamline repetitive data-entry workflows, reducing manual handling in routine operations.
MAR 2023
AI Data Operations Associate
Diliman Technology Laboratories Inc.- Prepared, cleaned, and validated training datasets for machine-learning models, applying quality gates before handoff to engineering.
- Executed annotation and labeling guidelines at scale, resolving ambiguous edge cases through systematic quality audits.
- Audited data integrity across systems, tracked recurring defect patterns, and documented process improvements.
- Worked directly with data engineers to refine annotation protocols, feeding error patterns back into model performance.
2024
Academic Tutor, Mathematics and Sciences
Private Tutoring Practice- Tutored a student from Grade 7 through senior high who gained admission to UP Diliman, Ateneo, and DLSU.
- Developed customized learning plans and transitioned instruction to online platforms.
- Emphasized deep conceptual understanding over rote memorization.
AUG 2022
Customer Service Representative
Concentrix, AT&T Account- Resolved complex billing and service issues using systematic problem-solving and Salesforce CRM.
- Managed escalations and tracked customer data to identify recurring service issues.
JUL 2018
Assistant to Site Engineer, OJT
Primeart Builders Inc.- Supervised quality control for tiling, plastering, and ceiling work on a five-storey school building.
- Documented daily progress of structural elements and verified fixture installations.
Technical fluency, grounded in operations.
The toolkit is intentionally practical: analyze the data, maintain quality, communicate the result, and keep the workflow moving.

Building the next layer.
Formal engineering training is now being paired with data engineering skills and a broader record of disciplined professional development.
B.S. Civil Engineering
Expected graduation is July 2027. Starting August 2026, the academic load is Thesis I and II, one major subject, and two PE subjects, allowing full-time work availability.
Japanese Language and Nursing Care Training
Completed an intensive online program focused on technical Japanese vocabulary and caregiving protocols while balancing full-time data analyst responsibilities.
portfolio_v1.0 / build log
This website is also part of the proof.
A lightweight static portfolio designed with liquid-glass surfaces, semantic HTML, responsive CSS, vanilla JavaScript, accessible motion, a working command palette, and a projects grid auto-synced from GitHub.
PAGASA Track Agent.
An autonomous agent that watches PAGASA cyclone bulletins, parses them with an LLM, computes the cone of uncertainty, and ships a live map - fully unattended.
PAGASA Track Agent
Scrapes the latest PAGASA tropical cyclone bulletin, extracts structured storm data with DeepSeek V3 under Pydantic schema validation, builds the tangential cone of uncertainty in GeoJSON, and auto-deploys an interactive Folium map to GitHub Pages on an hourly cron.

Interactive Photobooth Web Application
Feature-rich event photobooth application with real-time camera processing and instant output generation.
First load may take ~30s while Render wakes the free-tier service.
Watch Alley - Zero-Cost Viber Broadcast
Three merged PRs in the official Watch Alley repo. The flagship replaces a €100/mo Viber Business API with a native viber://forward deep link: one click opens Viber pre-filled with the watch name, the canonical URL on line 2 so Viber's crawler fetches the og:image, and specs truncated at word boundaries to fit OS URI limits.
Everything else I ship.
