Fig 1.1 — During Maisie's tenure at Credit Suisse, her work was to diagnose issues with high-frequency trading systems to ensure accurate quotation of various equity and commodity positions. The window demonstrates a Bloomberg Terminal's DLIB<GO> function, displaying a local-volatility (LVLC) implied-vol surface for USD/SGD whose ATM term structure is bootstrapped from the annualized standard deviation of ECB daily log-returns, while the strike-axis smile and risk-reversal skew are synthesized and animated in real time.

Fig 2.1 — During Maisie's tenure at Grab, verifying the binaries which will be deployed at scale both internally and externally became an integral part of her job. The first window displays a binary patch of a firmware signature check in radare2: seeking to 0x32c34 and writing opcode 0x75 over 0x74 rewrites JE to JNE, inverting the conditional so the validation branch is always taken. The second window displays signature-based firmware identification with binwalk, locating embedded YAFFS root filesystems and Base64 index tables by magic bytes and flagging Intel x86 NOP sleds through opcode-frequency heuristics.

Fig 3.1 — During Maisie's tenure at Traveloka, responding to incidents such as the CrowdStrike outage in 2024 became an integral part of her job. The window shows a disassembly of CrowdStrike's kernel-mode driver (CSAgent.sys) using IDA Pro, where the graph view demonstrates an out-of-bounds array index (R8 = [RAX + R11*8], R11 = 0x14) that resolves to an unmapped kernel address and faults on dereference, the page-fault pattern behind a ring-0 bugcheck.
