Frame
Turn vague stakeholder pain into a decision question, success metric, and caveat list.
Standard team workflow, compressed by automation.
Modern data teams win by shortening the path between stakeholder question and trusted decision artifact. My portfolio shows how Hermes Agent makes each stage faster without removing human judgment.
Ingest
Load public data, define schema, inspect fields, document missing operational signals.
QA
Use Hermes to generate data tests, anomaly checks, null checks, and reproducible audit notes.
Analyze
Build SQL/Python metrics, compare baselines, segment risk, and keep assumptions explicit.
Validate
Stress-test interpretation: association vs causality, proxy vs direct proof, signal vs action.
Package
Convert analysis into recruiter-readable dashboard, case narrative, and proof trail.
Ship
Push GitHub PR, preview on Vercel, merge to production domain, document next iteration.
Case studies that show the system working.
Each case demonstrates different analytics muscle: forecasting/planning logic and operations-risk triage.
Favorita Planner Exception Queue
Forecast baselines become planner-review candidates using WAPE, MAE, Bias %, Forecast Score, FVA framing, ABC/XYZ segmentation, and replenishment assumptions.
Forecast QAPlanner queueAssumption control
Olist Delivery SLA Risk
Late-delivery exposure, review-score association, and seller/category/region investigation candidates framed without unsupported root-cause claims.

Automation stack
Human-owned logic. Agent-accelerated execution.
Hermes Agent does not replace analyst judgment. It orchestrates repetitive work: code generation, file ops, browser checks, GitHub PRs, site deployment, and documentation discipline.
Hermes Agent
Task-executing AI assistant for analysis planning, code iteration, documentation, browser QA, GitHub workflows, and deployment automation.
Open Design
Generates recruiter-facing layout artifacts and case-study pages, then hands accepted HTML into a publish pipeline.
GitHub PR workflow
Every published change has a branch, commit message, reviewable diff, and deployment preview.
Vercel production
PR previews for review, main branch deploys to im-khang.com.
Recruiter readout
What this website proves.
I can operate like a lean AI-augmented analytics team: discover the business question, build the evidence model, document limitations, create a decision artifact, and ship it publicly with a modern PR/deploy workflow.
