Software Engineering Manager building reliable, compliant AWS serverless platforms. I run calm, high-performing teams and stay hands-on via design/PR reviews, targeted prototypes, and incident/problem management Stack: Lambda, Step Functions, EventBridge, API Gateway, SQS, DynamoDB, S3 SaaS: Snowflake, Salesforce Delivery: CI/CD (GitHub Actions/Jenkins, trunk-based), Observability (CloudWatch, New Relic, ReportPortal), SLIs/SLOs & error budgets. Impact: -65% manual, -38% pipeline flakiness, EUR 100K+ ROI

Led QE across 8 teams (on/offshore) and Set hiring/levelling, bar-raiser panels, coaching and OKRs → faster onboarding & predictability. Standardised CI/CD with Jenkins/GitHub Actions (trunk-based, staged, quality gates) and shift-left → cycle time −40%, test efficiency +30%. Platformised automation (Playwright/Cypress, Appium, Pact, k6) → 85%+ coverage. Containerised infra with Docker + ephemeral envs → €100K+ annual savings. Added ReportPortal/SeaLights to cut risk.

Modernised a legacy monolith into microservices (strangler). Designed and built 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/ops basics (structured logging, health checks, runbooks) for faster recovery.
