Top SchoolPavel Oliynyk is a Senior Scala Engineer based in London with over two decades of commercial software experience and more than a decade focused on Scala and distributed systems. He has repeatedly delivered production-grade, domain-driven microservice architectures across finance, government and adtech—bringing deep expertise in Scala 2/3, Play, Akka/Pekko, Cats, FS2, Spark and cloud platforms (AWS/Azure). Pavel has led technical teams and acted as solution architect on complex data and tax domains (MTD/income tax at HMRC) while also building high-throughput data pipelines and PII detection systems. Comfortable across the full stack and multiple languages (C#, Python, Go, Haskell), he pairs pragmatic engineering with strong domain modelling skills to turn ambiguous requirements into reliable, testable systems. An engineer who prefers durable patterns over hype, he often takes contractor technical-lead roles that bridge client needs and delivery.
