SDET / QA Platform Engineer / AI Quality Systems

I build the machinery that makes software quality visible, testable, and harder to fake.

At Binance, I work where QA meets backend systems, crypto workflows, CI/CD, observability, and AI tooling. My best work is not a test case. It is the platform around the test case.

Interview mode

Change the lens. The same career tells different stories.

Systems lens: I connect automation frameworks, CI/CD, dashboards, alerts, and AI assistants into one quality operating layer.

Systems map

Two repos, one quality platform.

`mTest` generates evidence. `qa_gateway` turns evidence into dashboards, alerts, workflow triggers, and AI-readable intelligence.

Framework

mTest

Python/Pytest automation for crypto custody flows: API clients, Selenium admin UI, Appium iOS approvals, E2E transfer journeys, reports, screenshots, and result upload.

  • Web + mobile + API in one Pytest flow
  • Queued transfers, staking, hot wallet whitelist
  • GitHub Actions on self-hosted Mac runners
Gateway

qa_gateway

Flask QA platform that reads automation results, visualizes trends, triggers workflows, powers QA GPT/RAG, sends WEA alerts, and reviews PRs with SafuGPT.

  • Dashboards and DB analytics
  • RAG over docs, PDFs, sheets, and QA data
  • AI PR review with score-based auto-approval

Career timeline

From research and backend tools to quality infrastructure.

Software Development Engineer in Test, Binance

Built and maintained automation platforms for crypto/blockchain systems, including QaGPT, PR review automation, approval monitoring, E2E web/mobile/API frameworks, CI/CD quality gates, and real-time QA dashboards.

The lab

Where QA becomes an engineering discipline.

These are the ideas I keep returning to: evidence, consistency, observability, and automation that can explain itself.

AI QA Assistant

QaGPT turns DB test data and documents into queryable insights, summaries, charts, and alerts. It reduces manual dashboard work and helps engineers ask better questions.

Crypto Custody E2E

Web admin action, mobile approval, API state, transfer history, and explorer links are validated as one business workflow, not isolated UI checks.

AI PR Review

GitHub diff ingestion, hunk-level chunking, SafuGPT file review, PR summary, quality score extraction, and optional auto-approval above threshold.

Research Instinct

Publications and patents across ML, SDN, Docker automation, and traffic classification shape how I think about systems and data quality.

Evidence board

Use the filters like an interviewer would.

Framework

Web + mobile + API E2E

Connected Selenium web actions with Appium mobile approvals in the same Pytest flows, then verified final state through transfer history and external links.

Platform

QA Gateway

Built a central platform for dashboards, workflow triggers, WEA alerts, QA GPT, RAG, PR review, and automation result analytics.

AI

QaGPT

Integrated LLMs, RAG, generated analytics code, image/chart output, and DB context to answer quality questions from real execution data.

Crypto QA

Approval integrity

Worked on smart approval monitoring and abnormal spender approval alerts, strengthening on-chain security awareness.

CI/CD

Observable automation

Added run IDs, execution time, status upload, dashboard links, screenshots, logs, and app/FE/BE version capture around automation runs.

Research

ML + SDN publications

Published work on news popularity forecasting and dynamic network traffic classification using supervised ML in Docker-based SDN environments.

Formation
