Senior PHP developer specializing in high-load APIs, monitoring, and release ownership.
GeorgiaWhat I'm looking for
I’m a senior PHP developer with 10+ years of experience, with the last 6 years focused on high-traffic sports betting media. I build and refactor native PHP systems (7.4–8.2), balancing performance with long-term maintainability.
My work centers on REST API design and integrations with external services and third-party data providers. I’m also hands-on with database performance—MySQL query optimization under load, schema refactoring, and speeding up reporting on large datasets.
I set up observability with telemetry and monitoring, including traces analysis and log-based dashboards in Grafana (Loki; previously Graylog, Elasticsearch, New Relic). On production systems, I value fast feedback loops and actionable visibility for reliability.
As Deputy Team Lead, I own releases and deployment on several high-load projects, run code review, and make architectural decisions. I also mentor developers and coordinate planning, estimation, and workload distribution across teams.
