Build calm, high-performing engineering teams shipping reliably in regulated FinTech. Hands-on via architecture reviews, critical PRs, incident management Stack: Lambda, EventBridge, API Gateway, SQS, DynamoDB, S3. SaaS: Salesforce, Snowflake Delivery: CI/CD (GitHub Actions/Jenkins), Observability (CloudWatch, New Relic, ReportPortal) with SLIs/SLOs & error budgets Lead onshore/offshore teams, hiring, levelling, OKRs, vendor management Impact: −65% manual, −38% pipeline flakiness, €100K+ ROI

Led QE across 8 teams (onshore/offshore). Set hiring, levelling, bar-raiser panels, coaching, OKRs. Standardised CI/CD with Jenkins/GitHub Actions (trunk-based, staged) & shift-left → −40% cycle time, +30% test efficiency. Platformised automation (Playwright/Cypress, Appium, Pact, k6) → 85%+ coverage. Docker + ephemeral environments → €100K+ annual savings. Added ReportPortal/SeaLights for observability.

Modernised legacy monolith into microservices (strangler pattern). Designed Java/Spring Boot REST services: domain modelling, validation, error handling, SQL integrations. Established CI/CD with Jenkins + Git (branching, automated build/test, artefact promotion, deployments) to shorten lead time and stabilise releases. Drove Agile delivery (Scrum): estimation, code reviews, pair programming. Added observability basics: structured logging, health checks, runbooks.
