CHO, MINSANG · PORTFOLIO 2026

I build systems that work in the field,and now design how agents work.

My career began maintaining C-based financial middleware servers and expanded across web, data, IoT, computer vision, and LLMs. Rather than leaving technologies as isolated features, I connect them into cohesive systems that operate within real user workflows and production environments.

NOW / CURRENT ROLE

02 / SELECTED PROJECTS

Projects

Select a project to see my role, implementation scope, and outcomes.

ROLE

Owned end-to-end delivery, from product planning and infrastructure design to frontend, backend, and database engineering.

CONTRIBUTIONS

Integrated external exchange APIs, implemented consolidated asset valuation and a mobile interface, and diagnosed query bottlenecks across roughly 300 million rows to optimize database performance.

STACK

Node.js · JavaScript · Exchange API · MySQL · Query Optimization

OUTCOME

Operated the platform for approximately 180 users against a dataset of roughly 300 million rows.

ROLE

Developed the vision tracking pipeline, broadcast-equipment integrations, backend and frontend applications, and deployment workflow.

CONTRIBUTIONS

Implemented DeckLink video ingestion, vMix API-driven scene control, player tracking, an extensible per-game modular architecture, and CI/CD.

STACK

Computer Vision · DeckLink · vMix API · React · Flask · GitHub CI/CD

OUTCOME

Delivered an end-to-end automation pipeline that converts video-analysis results into live broadcast scene changes.

ROLE

Led development of the sensor ingestion pipeline, backend, dashboard, and forecasting models.

CONTRIBUTIONS

Implemented Raspberry Pi-based data collection, real-time ingestion, dashboard visualization, and LSTM/ARIMA-based trend forecasting.

STACK

Raspberry Pi · Python · Django · Database · LSTM · ARIMA

OUTCOME

Unified field data collection, monitoring, and forecasting in a single operational service.

ROLE

Developed the full solution, from model training and optimization to visualization, backend services, and the monitoring dashboard.

CONTRIBUTIONS

Trained YOLO models, built the OpenCV pipeline, added multithreaded processing and detection-data delivery, and optimized execution on low-spec PCs.

STACK

YOLO · OpenCV · Python · Multithreading · Flask · Docker

OUTCOME

Maintained reliable detection performance and throughput under constrained compute resources.

ROLE

Handled industrial protocol analysis, data integration, and development of the React/TypeScript dashboard.

STACK

PLC · CC-Link IE Net · Packet Analysis · React · TypeScript · Flask

OUTCOME

Connected undocumented industrial equipment to a browser-based monitoring system through protocol analysis.

ROLE

Developed the Android application, location backend, P2P networking layer, and thermal-sensor integration.

CONTRIBUTIONS

Implemented GPS processing, JWT authentication, a Wi-Fi Direct P2P proxy, and thermal-camera data parsing.

STACK

GPS · JWT · Wi-Fi Direct · Android · Node.js · Thermal Camera

OUTCOME

Designed peer-to-peer relaying so nearby users could exchange safety data despite unreliable cellular coverage.

ROLE

Developed the recommendation scoring algorithm, Flask API, and React-based results interface.

CONTRIBUTIONS

Combined candidate evaluation criteria, conflict-exclusion logic, and recommendation retrieval into a single service workflow.

STACK

Scoring Algorithm · Python · Flask · React · Database

OUTCOME

Integrated the recommendation engine and user interface into a real-world operational review process.

ROLE

Designed and implemented the blockchain and distributed-storage architecture along with paper submission and retrieval services.

CONTRIBUTIONS

Built IPFS file uploads, NFT ownership records, and the workflow linking on-chain transactions to paper metadata.

STACK

Blockchain · NFT · IPFS · Flask · Database

OUTCOME

Created an architecture that preserves file-location and ownership verification even if the central server becomes unavailable.

ROLE

Owned Android BLE integration, the data-collection backend, and high-volume communication optimization.

CONTRIBUTIONS

Supported six concurrent BLE UART band connections, developed the Android receiver app, and built a server handling data from approximately 200 devices.

STACK
