Martijn Vegter
Java Engineer - Site Reliability Engineering at Adyen
Championing the technical adoption of Adyen’s Private Cloud, including containerization efforts, datacenter onboarding and decommissioning, capacity planning and improving the overall operational maturity.
Participating in on-call rotations, playing a key role in post-mortem analysis and consistently applying learnings to prevent future occurrences of similar issues.
Implemented an algorithm for the payment to accounting cluster allocation, resulting in a 46% decrease in accounting operations platform-wide and a decrease of 65% for franchisee-model customers. Subsequently this allowed for horizontal scaling of the accounting clusters with a minimal increase in overall accounting operations.
Collaborated with cross-functional teams to replicate the entire Adyen architecture in Indian data centers. This enabled the expansion into the Indian market by securing the Payment Aggregator License from the Reserve Bank of India.
Introduced an open-source Gradle dependency analysis tool to enable modularization efforts on the Adyen monorepository. This resulted in a 70% decrease in build time for core framework modules. Contributed various bug fixes to the upstream project.
Improved overall database cluster performance by implementing partition strategies for various products. This allowed for changing the maintenance strategy from deleting rows to dropping older partitions reducing vacuum frequency, and improving query performance by means of partition exclusion.
Mostly focused on investigating and optimising web application performance. Contributing to core internal frameworks related to caching, communication and databases.
