Data Systems Lynxes: Graph Analytics Engine 2026 / Built project / Public
Problem
Existing Python graph libraries and generic dataframe wrappers often struggle to combine memory efficiency, traversal performance, and lazy query optimization for large graph analytics.
Key decision
Designed GraphFrame to own Arrow RecordBatches directly.
Outcome
Established the foundation for a graph analytics engine with Arrow columnar memory, CSR-based traversal, and lazy collect execution.

AI-DLC / MLOps Contexta: Local-First ML Observability 2026 / Built project / Public
Problem
ML experiments and deployment work often scatter metadata, records, and artifacts across tools, making reproducible local observability hard to maintain.
Key decision
Used a `.contexta/` workspace as the home for separated metadata, records, and artifact storage.
Outcome
Implemented a local observability foundation for consistently managing and inspecting ML execution history and artifacts.
Open detail
NLP / LLM EMR-Based Nursing Surveillance for Automatic ICD Coding 2025 / Published work / Summary available
Problem
Nursing surveillance required diagnosis-related classification, but key clinical signals were fragmented across heterogeneous EMR sources.
Key decision
Trained two KM-BERT models independently and averaged raw logits to stabilize text representation.
Outcome
The final model was reviewed for practical classification behavior rather than a single standalone score, including rare-class recall and available-data constraints.

Internal Commerce Platform 2024

Dalkom Shop: Internal Employee Mileage Commerce Platform

AI-DLC / MLOps · Built project

AI-DLC and Operational MLOps Engineer Summary available

The project needed cloud infrastructure and platform foundations that could reliably support search, notifications, admin workflows, and ongoing operations.

Key decision Organized CI/CD and cloud foundations so the React and Spring service could fit into a deployable, monitorable workflow.
Data Surface
structuredimagehybrid
Outcome / review signal Built a practical service foundation for a closed internal mileage commerce platform.
LLM Application Prototype 2024

Devridge: LLM-Based Feedback Bridge for Developers

NLP / LLM · Prototype

Applied NLP and LLM Research Engineer Summary available

Developers working alone often need UI, performance, or code quality feedback, but they rarely have an easy way to gather role-specific input at the right time.

Key decision Separated role constraints and contextual input so responses stayed scoped instead of generic.

Outcome / review signal The prototype showed how structured prompting can make LLM feedback more useful for project review.
Collaborative NLP Project 2023

BloGeek: AI Modules for a React + Spring Blog Project

NLP / LLM · Built project

Applied NLP and LLM Research Engineer Summary available

The product needed ML components that could classify emotional polarity and generate stylistic variations of text to support richer blog content workflows.

Key decision Used KoBERT for polarity recognition and KoBART for style transfer.
