Quality Assurance Engineer exploring AI-assisted quality engineering β€” 13+ years across telco, banking & insurance.

I use these repositories primarily as a learning and engineering workspace.

My goal is not to collect technologies or build impressive demos as quickly as possible. I use the projects to organise and deepen what I already know about software testing and automation, while deliberately expanding into Python, AI and LLM-based systems.

A large part of that learning happens through building and questioning things:

  • revisiting software-testing and automation fundamentals in working code,
  • improving my Python and engineering skills through real implementation problems,
  • learning how modern AI systems work by testing where they help, where they fail, and where deterministic controls are still necessary,
  • turning useful experiments into practical QA tools.

The result is gradually becoming a small, internally consistent testing ecosystem rather than a collection of unrelated repositories.

πŸ”­ What I'm building

Project What it does
πŸ”₯ PhoenixQA AI-assisted self-healing test automation framework with Safe/Autonomous execution, failure classification, controlled recovery strategies, and measurable healing experiments.
πŸ› defect-pilot Privacy-first Jira defect enrichment assistant that checks ticket completeness, identifies critical gaps, safely enriches available context, and routes actionable defects using explicit project rules.
πŸ§ͺ llm-qa-toolkit Experimental LLM evaluation framework exploring Test Basis, evaluator authority, evidence, gradability and the limits of LLM-as-a-judge approaches.
πŸ—οΈ qa-automation-framework Reusable Playwright + pytest automation skeleton built around POM/SOM principles and enterprise-style UI/API testing.

These are not intended to be isolated demos.

qa-automation-framework provides reusable automation structure. PhoenixQA explores runtime recovery and maintenance. defect-pilot explores defect-quality workflows. llm-qa-toolkit turns the same testing mindset toward AI systems themselves.

Different problems, but the same underlying question:

How can AI support software testing without replacing evidence, engineering discipline and human control?


🧠 How I work

I use AI heavily, but I don't treat generated code or generated conclusions as a black box.

My background is software testing rather than software development, so I approach these projects primarily through SDLC/STLC, risk, testability and evidence. I bring practical experience with enterprise systems, SQL, REST/SOAP integrations and test design, while deliberately expanding the programming side through Python, Playwright, pytest and related tooling.

For automation I try to preserve familiar engineering boundaries such as Page Objects, Service Objects, separation of test data and logic, deterministic checks, explicit acceptance criteria and regression evidence.

I rarely treat the first technically working solution as the final one. Before claiming that an approach works, I try to understand the alternatives, assumptions and failure modes behind it β€” and, where possible, test them against evidence.

That sometimes makes the projects slower and more exploratory than a typical implementation project. A feature may lead to a diagnostic experiment, an architectural change, a rejected approach or even a reduction in project scope. I consider that part of the engineering work rather than wasted effort.

I prefer a smaller claim supported by evidence over a more impressive claim supported only by working code.

A seemingly small implementation question can therefore turn into:

implementation
    ↓
unexpected behaviour
    ↓
test
    ↓
architectural question
    ↓
alternative approaches
    ↓
experiment
    ↓
documented limitation
    ↓
new hypothesis

That reasoning is deliberately preserved in files such as LEARNINGS.md, testing strategies, architecture decisions, known limitations and research hypotheses.

The repositories therefore show not only the current code, but also how and why it evolved β€” including approaches that were tested and later rejected or deliberately narrowed.


🌱 What I'm currently learning

  • practical limits and useful applications of LLMs in software testing,
  • reliable evaluation of AI systems and the weaknesses of LLM-as-a-judge,
  • self-healing and maintenance of automated tests,
  • human-controlled vs autonomous AI-assisted workflows,
  • Python and software-design practices needed to turn QA experiments into maintainable tools,
  • CI/CD, reproducibility and measurable validation of AI-assisted behaviour,
  • local vs cloud LLM trade-offs for enterprise and sensitive test contexts.

A recurring principle across the projects is:

LLM proposes; evidence, deterministic controls and humans define what may be trusted.
