Hi, I'm Olivia.

Top-three Korean financial group · 7-month engagement

Mapped statutory accountability for 6 executives under a brand-new regime

Korea's senior managers regime had just landed with no domestic precedent, so I researched the UK original, then worked across business and control functions to break executive duties (covering technology, AI, and asset management) into department-level controls. The manuals department heads use today came out of that.

Leading Korean securities firm · first external IT audit

Turned 40+ interviews into an audit method that didn't exist yet

Co-owned the scope that had to outlive us: a risk pool across five audit domains, a quantitative scoring model grading every area from priority to monitoring, and a security architecture for external LLM use. Codified into a seven-chapter manual written for non-specialist auditors, plus Tableau dashboards embedded on the firm's own platform with drill-down for the audit team and aggregate trends for executives.

A large Korean securities firm · joint IT and information security audit · 2023 · sole scope owner

Designed controls for MyData, cloud, and robo-advisory with no audit precedent

Sole owner of the emerging-technology theme review on a seven-week joint audit, two years before the engagement below. MyData, cloud and robo-advisory were where fintech partnerships were being built on infrastructure nobody had audited yet, so every control had to be reasoned from first principles rather than pulled from a library.

Financial institution clients · cross-team process design

Traced repeated requirement rework to one cause: six teams, six vocabularies

Compliance, risk, technology, security, strategy, and vendor teams were using the same terms to mean different things, so requirements kept getting rebuilt. I built a shared glossary and cross-check process, adopted on two implementations.

Bank & securities group · post-regulatory-change remediation

Sequenced 10 remediation initiatives, then shipped 18 compliance screens on schedule

After regulators tightened conflict-of-interest rules for dual-role executives, I ran 30 interviews to score and sequence the response, then owned functional design through to live screens. Analysis and delivery in the same pair of hands.

Korean insurance subsidiary · first-time lead consultant

Benchmarked 12 sections of a global IT asset standard against local reality

First engagement as lead: benchmarked the subsidiary against its group standard across 12 sections and reconciled ServiceNow CMDB records against physical assets. The gap analysis and a 7-process ownership redesign became the local team's remediation plan.

Findings and remediation detail remain client confidential.

Systemic financial market infrastructure · 5.5-month engagement · 2023

Redesigned KRI governance from monthly batch reporting to real-time alerting

Sole owner of the indicator workstream. Moved ownership from the second-line risk function to the business units under a three-lines-of-defence model, designed a two-tier breach and escalation architecture, and connected breaches to loss events and control improvements, which had been three separate processes. Separately co-designed the Basel III standardised-approach operational risk capital methodology with the engagement director, benchmarked against DTCC, Euroclear and Clearstream from primary PRA, FSB and IOSCO sources.

Top-five Korean life insurer · Basel III operational risk system build · 2023

Built the indicator and control layer of a Basel III operational risk system

Owned a third of the technical workstream on a four-month build. Defined 9 key risk indicators across 9 departments, each specified down to formula, source system, interface ID and target table, with statistical thresholds set on a 24-month moving average at 95% and 99% confidence. Wrote 13 of roughly 40 screen specifications with role-based permission matrices and approval workflows, and validated a decade of loss data across two legacy systems left over from a merger. Detection lag went from quarterly to monthly.

Suwon City Hall · Smart City Division · Team Leader · 2021

Built a composite risk scoring model on a 250m grid, and six of its recommendations became city policy

Merged 30+ datasets (40,000+ police call records, floating population, CCTV and lighting infrastructure, demographics) onto a standardized 250m × 250m grid. Multi-criteria decision analysis with consistency-ratio validation set the weights, K-means clustering classified the grids, geospatial analysis in QGIS mapped them. Grand prize at the city's public safety big data competition.

Suwon City Hall · Smart City Division · led a 4-person team · 2021

Built a text classification pipeline that sorted 10,600 complaints at 87% accuracy, cutting manual effort 85%

An end-to-end NLP pipeline: morphological parsing, TF-IDF vectorization, LDA topic modeling that surfaced 23 complaint themes, then a Naive Bayes classifier trained on 2,000 labeled samples and applied to the full corpus. Average resolution time fell 23%, and three neighboring cities reused the framework. Top prize at the Ministry of the Interior and Safety's national public big data competition.

Suwon City Hall · Smart City Division · Data Analyst · 2021

Designed the metric framework a city allocated relief budget against, then replaced monthly PDFs with self-serve dashboards

Credit-card transactions, mobile GPS foot traffic, and demographics sat in incompatible geographic units, so I built a crosswalk in GIS to join them. Then defined the KPIs the city would actually decide on: revenue decline, foot-traffic reduction, a weekly recovery index, a composite vulnerability score, with segmentation by business type, district, and time slot, and shipped a three-tier self-serve Tableau dashboard that fed executive economic briefings.

Seoul Metropolitan Government delegate · CES 2022, Las Vegas

Generated 258 leads and closed 3 contracts for a Korean AI startup's US entry

Segmented buyers out of the exhibitor database, then ran 69 meetings delivering English pitches and demos. The contracts and letters of intent that came out of it reshaped the startup's roadmap.

Kyung Hee University · Project Lead · 2022

Ran regression, ANOVA, and time-series decomposition on thirty years of global energy data

Enerdata and World Bank data, 1990–2020. Regression controlling for GDP and population as confounders, ANOVA across blocs, and ARIMA time-series decomposition to isolate the 2008 and COVID shocks. Delivered as a reproducible R Markdown report plus an interactive Shiny dashboard. Global consumption rose 73% over the period; 2020 was the steepest single-year drop in thirty years.

Korea Employment Information Service competition · 2022

Placed top four by public vote with a user-centered employment analytics dashboard

A job-market dashboard built for people actually looking for work rather than for the agency publishing the data. Pipeline through interface, built solo.

Trusty · Co-Founder & Product Lead · 2019 to 2020

Founded a women's health platform on 300 user interviews and hit 120% of its funding goal

A 2017 scandal found harmful substances in most Korean menstrual products, and no app told anyone which ones were safe. We partnered with a testing institute and a university lab to turn chemical analysis into consumer-readable safety scores, then built a recommendation engine on top. Coordinated engineers, medical advisors, and three research institutions; secured ₩50M+ across three programs.

KPMG · Digital Group · Digital Consulting Intern · 2022

Turned 25 departments' requirements into one documented cloud evaluation model

Consolidated cloud HR platform requirements from 25 departments into a central requirements database covering functional needs, integration points, compliance, and UX. Assessed vendors within a 27-vendor review on modules, ERP integration feasibility, and data-migration risk. The framework replaced subjective debate with documented criteria for leadership's decision.
