EXPERIENCE

KB Securities

Nov 2025 – Aug 2026

Software Engineer Intern

Engineered a real-time terminal tracking 30 stocks and 300+ covered warrants for KB Financial Group traders, modelling 54 pricing, risk and P&L metrics from Black-Scholes outputs, Greeks and inventory exposure. Cut WebSocket payloads 84% by sending differential patches instead of whole snapshots, and upstream requests 98% by batching 50 symbols per call; historical series moved into Redis in front of indexed Postgres queries over 100,000+ records. Shipped the CW Portal on a two-VM split — Next.js behind Nginx, containerised FastAPI, Kafka and Postgres — with 16 REST endpoints under pytest, and n8n pipelines handling deduplication, normalisation and adjusted-price snapshots.

MINI CHALLENGE

Feed the hungry blob

Click anywhere in the top half of the arena to drop a snack. The blob hops around on its own — land the food on it.

Bitter coffee falls as often as the treats, and hammering the arena only makes it worse. Aim, don't flood.

  • DONUT+1 PTS

FEED THE HUNGRY BLOB

Drop snacks from the top half into the blob's mouth. Bitter coffee is just as likely to fall, so aim instead of spamming.
