Summary
👤
Senior🎓
Top SchoolDanielle Mustillo is a Site Reliability Engineer and senior platform developer with 12 years of experience designing cloud-native, distributed systems and improving SDLC efficiency. She combines strong software engineering skills in Golang, Python and Java with hands-on expertise deploying Istio service mesh, GitOps (FluxCD), Thanos observability and Flagger canary releases to deliver lower latency, reduced costs and higher resilience. At Aduna and Ericsson she led cross-functional teams to cut latency up to 65%, replace API gateways to save >$180k/yr, automate certificate management across 100+ clusters, and shrink release lead time for 70+ developers. She contributes to open-source tooling—improving mtail’s semantic checker to give users tunable performance/flexibility trade-offs—and builds automation that turns security and non-functional testing into daily production workflows. Based in Montreal, she pairs pragmatic engineering with measurable business impact and a knack for turning operational pain points into self-service platforms.

Contributions summary:Danielle primarily contributed to the `mtail` project by implementing configurable semantic checker threshold values. This involved modifying the semantic checker to allow for adjustable values related to recursion depth and regular expression length. The changes included modifications to the `checker.go`, `loader.go`, `cmd/mtail/main.go`, `checker_test.go`, `compiler.go`, `mtail.go`, `compiler_test.go`, `vm_integration_test.go`, and `loader_test.go` files and other supporting test files. The changes increased flexibility and performance trade-offs for users of the mtail program.
