"QA is not a phase at the end of a sprint — it's a continuous investment in user trust and business resilience. Every defect caught before release is a customer retained and a reputation protected." — Ruslan Peyter, Senior QA Engineer
QA Strategy

Owning quality from strategy to sign-off

🗺️
Platform-Wide Test Strategy
Defined end-to-end test strategy for a digital banking platform serving 200+ credit unions — covering web, mobile, API, and core banking integration layers.
Adopted across 4 dev teams
⚖️
Risk-Based Testing Approach
Introduced risk-based test prioritisation focused on financial transaction flows, authentication, and data integrity — ensuring highest-risk areas received maximum coverage.
Critical defect detection up 40%
🚦
Entry & Exit Criteria
Established clear QA entry and exit criteria for each release phase — giving product, development, and stakeholders objective release readiness signals.
Release confidence measurably improved
🔁
Shift-Left Implementation
Moved QA involvement to the requirements and design phases — catching ambiguities and risk early, before a single line of code was written.
Bug fix cost reduced significantly
Pillar 01
Coverage Over Completeness
Prioritise meaningful test coverage of critical business flows over 100% line coverage that provides false confidence.
Pillar 02
Quality is a Team Sport
QA is embedded in every sprint ceremony — from grooming to retrospective. Developers write testable code; QA designs tests early.
Pillar 03
Data-Driven Decisions
Quality decisions backed by defect trends, escape rates, and coverage metrics — not gut feel or verbal sign-offs.
Pillar 04
Compliance by Design
Security, privacy, and financial compliance (PCI DSS, OWASP) are not afterthoughts — they're built into the test strategy from day one.
Problems I Solve

Your challenge.
My expertise.

🕳️
Gaps in Test Coverage
Critical paths go untested, bugs reach production, and no one knows what's actually covered. I design structured test suites that eliminate blind spots.
Full-spectrum test coverage
🐢
Regression Slowing Sprints
Manual regression eats sprint capacity. I build efficient, reusable regression suites that give teams back their velocity without sacrificing confidence.
Optimised regression cycles
🔌
API & Integration Failures
Data flows silently break between services, core banking systems, or third-party APIs. I catch contract violations and data integrity issues before they reach users.
End-to-end API validation
🗄️
Database Integrity Issues
Financial data silently corrupts — wrong balances, missing transactions, broken references. I validate business logic at the database level, not just the UI.
SQL-level data validation
☁️
No Visibility in Cloud Environments
Issues hide in logs nobody reads. I set up systematic AWS CloudWatch monitoring and log analysis so problems surface in minutes, not after user complaints.
AWS log triage & monitoring
🏦
Core Banking Nobody Wants to Touch
Symitar Quest and Corelation KeyStone integrations are complex and risky. With 11+ years of fintech QA, I know exactly what to test and where failures hide.

Test Data Management

Financial data testing
done right.

Test data management in fintech is uniquely complex — real account numbers, transaction histories, and PII cannot simply be copied into test environments. With 11+ years in digital banking, I know how to build safe, realistic, and compliant test data strategies.

From masking production data to generating synthetic financial scenarios, I ensure tests are meaningful without compromising privacy or compliance.

🎭
Data Masking & Anonymisation
Replacing sensitive PII and financial data with realistic synthetic values for safe use in test environments.
🏗️
Synthetic Data Generation
Creating representative member accounts, transaction sets, and loan scenarios that mirror real-world banking complexity.
🔄
Test Environment Data Consistency
Ensuring data states are reproducible, consistent across environments, and reset reliably between test runs.
🔐
Compliance-Aware Testing
Aligning test data practices with PCI DSS and GDPR requirements — no real card numbers, no unmasked PII in test logs.
Working Style

How I work

📡
Async-Friendly
Comfortable working across time zones with distributed teams. I document clearly so nothing is lost between standups.
Remote-ready
🎯
Outcome-Focused
I connect QA work to business goals — not just test counts. Every defect I catch has a cost, and I communicate that cost clearly.
Business-minded
📝
Documentation-First
I write clear test plans, bug reports, and runbooks. Teams I join inherit structured QA artifacts, not tribal knowledge.
Process-oriented
🔗
Cross-Functional Communicator
I bridge developers, product managers, and stakeholders. Fluent in technical depth and plain business language equally.
Multilingual
⚡
Fast Ramp-Up
New codebases, new domains, new tools — I get productive quickly. My fintech depth means less time explaining context, more time finding issues.
Self-directed
🧩
Collaborative by Default
QA is a team sport. I work with developers early, not at the end — shifting testing left and building quality into the process.

FAQ

Common questions

Yes. I am actively considering opportunities in Europe. I am also open to fully remote roles with global teams.

I'm open to full-time employment, B2B contracts, and long-term freelance engagements. I prefer stable, ongoing collaboration over short one-off projects.

Both. My background is enterprise fintech, but I adapt well to startup pace. I bring structure without bureaucracy — useful for fast-moving teams that need QA processes to scale with the product.

I'm based in Central Europe (CET/CEST, UTC+1/UTC+2). I have experience working with US-based teams and am comfortable with flexible hours to accommodate overlapping time zones.

I do both — I have strong manual testing fundamentals (boundary value analysis, equivalence partitioning, exploratory testing) and also build automation, primarily with Playwright for UI and API testing, with CI/CD integration via GitHub Actions and Allure reporting. I also use AI-augmented tooling like Cursor with Playwright MCP, Claude Cowork, and n8n to speed up test creation and workflow automation.

I can typically start within 2–4 weeks of an accepted offer, allowing time for proper handover and onboarding preparation.
