I untangle fragile microservice architectures and make them boring again. I’ve modernized fragmented microservices for hyper-growth companies, migrated Riak → Postgres under hard deadlines, and turned chaotic legacy systems into stable, scalable platforms. Recent impact Overhauled business-critical messaging systems for high-volume, low-latency workloads. Simplified/retired 11+ microservices, reduced latency, and improved observability — enabling a hyper-growth partner launch ahead of competitors. Led discovery, design, and delivery of an auditable, multi-source, high-throughput inventory tracker — giving an e-commerce client immediate stability and a scalable foundation for years of growth. Migrated an auth database from Riak → Postgres under a hard deadline (World Cup traffic). Zero downtime and smooth scaling through peak load. Ideal clients Berlin/EU scale-ups with distributed systems complexity — fragile
microservices, data-intensive platforms, or legacy architecture that's become
a liability. €100+/hr retainer. Fixed-bid projects also considered.

I learn new things extremely quickly. AWS preferred but not required (I hold a variety of certs, available here: https://www.credly.com/users/jon-north.ad78f0c8) You will like working with me because I: * built the primary streaming data architecture for realtime game player tracking information (all games, 50ms SLA) and game stats for one of the top 3 US sports leagues (can’t name drop!) using Redpanda/Kafka on Azure+Terraform, and implemented its developer portal using Gravitee to provide first class streaming API support and monetization. Also built, deployed and maintained their ask-a-question-get-a-true-answer AI bot to expose 20+ years of stats to natural language fan questions! (this was the third of currently four times I’ve built similar architectures for different companies) * Implemented a vector DB for one of the leading AI image hallucination platforms (millions of users) to provide an image similarity service. * replatformed dozens of complex quant jobs to AWS Lambda for a startup hedge fund (~$1B AUM), vastly improving QoS and maintenance cost. Line 1 to platform-in-prod time 3 months, including refactoring for fit. This was mission critical cannot-fail stuff and required extensive proof of correctness. * built a framework to collapse dozens of singleton ETL programs into one config-driven, simple C# application performing the same functionality at ~80% reduction in maintenance cost year over year.
