Platform Engineer & DevOps

I build and operate the platform that backend services run on: infrastructure as code, deployment, observability, cost, and security. I come from backend engineering, so I work on both sides of that line.

Certifications

AWS Developer Associate Engineer Information Processing SQLD

Career

Platform Engineer & DevOps · 2026-06 – present

  • Infrastructure platform — brought a console-built AWS environment under Terraform with OIDC-based workflows
  • Observability — monitoring managed as code, alerting moved to SLOs
  • Deploy & cost — improved the internal deployment pipeline (blue-green); traced where the cloud bill comes from and cut it
  • Security — default-deny authorization, column-level encryption of personal data, ISO 27001 / ISMS-P preparation

TeamBind · Backend Engineer / CTO · 2025-07 – 2026-06
A space-booking and community platform for musicians

  • Designed and built a microservices architecture as the sole backend engineer
  • Built and operated a self-managed (on-premises) Kubernetes cluster, including incident response
  • Designed database schemas and data models for core services
  • Developed web and app backends end to end

Open Source Contributions

Security Research

  • OpenTelemetry Java instrumentation — GHSA-9pmw-7q9q-j3jc: Reported a SQL sanitization flaw that could expose sensitive string literals in span attributes; credited as the reporter. Fixed in Java agent 2.33.0.

Merged

Project Contributions
Flux
pkg/ssa
#1377 Added an optional callback that reports ownership conflicts from SSA’s existing object lookup, allowing controllers to warn before applying a resource without an extra API request
OpenTelemetry
Java instrumentation
• #20845 Fixed the agent no longer propagating context through Reactor operators after the application calls Hooks.resetOnEachOperator(), which broke the context of externally driven Flux.create subscribers
• #20659 Fixed @WithSpan on a Flux requesting 32 elements from the source regardless of downstream demand, which dropped queued work on cancel
• #20658 Fixed Spring Kafka listeners with async acks or async return types emitting a duplicate Kafka client process span per record (a 2.32.0 regression)
• #20660 Fixed MySQL/MariaDB address=(host=..)(port=..) JDBC URLs without a subprotocol losing server.address/server.port
• #20661 Fixed the Lettuce library reporting the command name (e.g. BLPOP.) as error.type on client-side timeouts
Spinnaker
Orca
• #8174 Fixed a race where a duplicate StartExecution delivery could move a completed pipeline back to RUNNING, using a conditional status update (SELECT ... FOR UPDATE)
• #8208 Made StartExecution's rollback after a failed StartStage push conditional, so a cancel made in that window is no longer overwritten and the redelivered message doesn't start the canceled pipeline (reproduced against MySQL)
• #8209 Added a test that depends on the row lock in updateStatusIfExpected; it fails if SELECT ... FOR UPDATE is removed
Debezium • #8220 Fixed a regression in the generated MySQL DDL grammar where ALTER DATABASE without a database name failed to parse and stopped the connector
• #8225 Fixed the MariaDB and legacy MySQL grammars taking DEFAULT as a database name in ALTER DATABASE DEFAULT CHARSET ..., which silently skipped the charset change (follow-up requested by the maintainer)
ANTLR grammars-v4 • #5037 Made the schema name optional in the MySQL alterDatabase rule, the upstream source of the Debezium grammar fixed in #8220
• #5039 Fixed the MariaDB grammar taking DEFAULT as the database name in ALTER DATABASE DEFAULT CHARSET ..., upstream of one of the two grammars fixed in #8225 (the other, Positive-Technologies, is deprecated upstream and not accepting fixes)
Keycloak #53990 Fixed AccessTokenContext validating grantType twice instead of rawTokenId, so a null token id reached the encoded token id as the literal null rather than failing at construction
Lettuce
Redis Java client
• #3952 Fixed DefaultEndpoint validating clientOptions twice so a null clientResources bypassed the null check and surfaced later as an NPE away from the construction site
• #3955 Fixed assertion messages that named the wrong argument: a misspelled ReauthenticateBehavior in a public builder, and CompressionCodec reporting a null output stream as the input
• #3954 Fixed typos in the Javadoc of the stream XACK and XLEN commands across every API flavor, plus other comment typos
Spring Cloud Config #3342 Expired the Git refresh rate when /monitor receives a webhook, so refreshed applications get the new commit
Spring Security #18855 Applied the javadoc-warnings-error policy to the spring-security-aspects module, aligning it with the rest of the build
Micrometer #7256 Documented Jakarta Mail instrumentation and registered it in the Observation instrumented-projects reference

In Review

Project Contributions
Flux
kustomize-controller
#1807 Add warning events when a Kustomization overwrites resources owned by another Kustomization, making silent ownership conflicts visible

Writing

I write up what I learn on my blog: SRE and observability, IaC work logs, incident response and more (180+ posts).
