Senior engineers who sweat the hard parts.
Mozek is a small, deliberately boutique team. No layers, no juniors learning on your budget — just senior engineers who have built and operated data, cloud and AI systems at scale, and who stay hands-on from first whiteboard to production on-call.

Calvin Fernandes
Distributed Systems & Data Engineering Lead
An accomplished software engineer and solutions architect with more than a decade of experience building distributed systems, cloud-native platforms and large-scale data solutions across media, sports betting, financial services, loyalty and advertising technology. With deep expertise in Scala, event-driven architecture, stream processing, AWS, Kafka, Cassandra, DynamoDB and Spark, he has led resilient, high-throughput systems from architecture and implementation through observability and production support. An active open-source architect and mentor, Calvin also helps engineering teams adopt scalable designs and modern functional-development practices. He has notably contributed to open-source projects such as Virgil, ZIO and Trace4Cats, used in environments that demand every bit of performance, including Disney+, SiriusXM and Morgan Stanley.
A clear path from outcome to operation.
Discover
We map the business outcome, constraints and the systems already in play.
Architect
A pragmatic design that fits your team, budget and reliability needs — not a reference diagram.
Build
We ship in tight increments, with tests, observability and documentation from day one.
Operate
We hand over cleanly — or stay on to run it — so the system keeps delivering after launch.
Boutique by design.
We stay small on purpose. It keeps the people you meet the same people who do the work — and keeps our advice honest.
