Choose a case for the role you are hiring: CEX product quality, automation leadership, or technical support. Each case explains my contribution and the result.
Case 1 · 2023–2024
Automation planning and team leadership
6 automation engineers led across three ASML HMI modules
Designed the setup-to-reset lifecycle within the existing TestComplete architecture so the normal workflow could run unattended; the team implemented most of the code. Implemented a portion of test cases as Python automation scripts within the TestComplete framework and reviewed the team's code.
Case 2 · 2010–2023
Enterprise QA and support engineering
−20pp first-month SEG-to-L2 missing-info returns after the DLP diagnostic guide (manager-reported)
As SEG Leader, checked escalation evidence and assigned cases by priority, complexity, and workload. Took part in interviewing candidates during the DLP period (self-reported).

Case 3 · 2024
CEX product quality
3 high-severity defects escalated across trading, commission, and conversion
Tested wallet, referral, spot, futures, convert, fees, funding, liquidation, and KYC. The case also records what remained unresolved when I left.
My experience spans crypto exchange testing, security incident investigation, and test automation.
Senior QA Engineer · centralized crypto exchange
Tested Wallet, Referral and Affiliate, Spot, Futures, Convert, fees, funding, liquidation, and KYC on BTSE's centralized crypto exchange. Identified and escalated three high-severity defects across trading, referral commission, and conversion flows.
Project Leader / Senior Automation Test Engineer
Led six Automation Engineers across three ASML HMI modules. Designed the setup-to-reset lifecycle within the existing TestComplete architecture so the normal workflow could run unattended. Planned reusable modules and technical handover; the engineers completed most implementation coding.
QA Engineer → Senior Customer Service Engineer → Senior QA / Customer Service Engineer · QA Leader and SEG Leader
As SEG Leader, I checked escalation evidence and assigned cases by priority, complexity, and workload. I initiated a DLP diagnostic guide; manager-reported figures showed a 20-percentage-point drop in missing-data case returns in its first month. I also built Python monitoring for Chrome updates and proposed a supported-site scanning design to reduce resource use. Received internal SEG awards in 2019 and 2021.
I build tools around real constraints: traceable data, explicit guardrails, and workflows another person can verify.
Python / pytest · REST and WebSocket testing
Tests public market-data snapshots and updates for stale events, sequence gaps, and invalid order-book values. Includes test design, executable checks, and versioned results. Uses Binance public APIs; separate from my employment at BTSE.
Public market data only. No account, order, or funds testing. Live results apply to the recorded revision and date.
Portfolio demonstration. Check each record's scope, revision, and freshness before interpreting its status.
A dashboard for reviewing test results and evidence
A passing result needs a tested version, a clear scope, and supporting evidence.
Consolidates test evidence from two repositories into traceable release decisions. Each row shows the decision, rationale, and evidence link. The dashboard keeps freshness, Unknown states, Gate Flow, and sanitized public boundaries explicit.
Static page · no external requests
A self-contained sample of several agents checking one change before the gate gives a decision. It is a demonstration, not a live product result.
