Owned Site Reliability, Platform, Cloud, Performance, Security, and Machine LearningSite Reliability Engineering: Migrated from synchronous/blocking cURL request to logging via to Datadog Agent over tcp (rather than file based logging). End-to-end observability into our platform. Decrease time to investigate issues. Added significantly more logging & dashboardsPerformance Engineering: Automated adding index to FKs on mySQL tables, and labeling all FKs as such. Implemented a Caching layer (on filesystem and hardcoding, to decrease queries). Load testing with Grafana K6. Worked on the async flow as our PHP based monolith can\'t do multithreading, and we wanted to decrease customers\' latencySecurity Engineering: Remediated 5/6 of the >= Low sev issues in pentest report. We scored 6/6 on the retest! Set up content security policy. Detected Cloudflare WAF (web application firewall) blocking real customers\' traffic! Compliance: Assisted in PCI DSS & SOC2Machine Learning: Given my ML background, I set up snowflake, we saw the costs, decided to roll our own ML flow instead. SQL -> Lambda (forecasting per customer, or per fee type)-> SQL -> Preset (BI tool)Cost optimization: Deprecated Datadog Serverless with Datadog logs (Saved USD $4800/yr), Decreased unneeded logs (Saved USD $2400/yr), Various AWS cost optimizations (USD a tech team of 8 engineers, I was the sole direct report of the CTO. So I hoped around and worked on everything except Frontend & business logic on backend.
