As a Staff Software Engineer at Cloudera, I contribute to developing scalable, secure, and efficient distributed systems with over five years of expertise in Kubernetes, microservices, and Java. Recent accomplishments include leading the design of a SAML 2.0 authentication layer, centralizing login for customers, and enabling seamless corporate SSO integration. Collaborating with cross-functional teams, I built an embedded Docker registry adopted by over 100 PoC customers, simplifying deployments and enhancing user experience.  

My mission is to streamline and secure data service platforms through innovative engineering solutions. Focused on delivering impactful results, I have driven critical vulnerability resolutions within strict SLAs and automated workflows to maintain audit readiness. Dedicated to knowledge sharing, I developed workshops that reduced installation escalations by 30%, empowering teams to tackle complex challenges. Passionate about distributed systems, I aim to enable organizations to optimize their infrastructure and achieve operational excellence.

## Work Experience
### Staff Software Engineer @ Cloudera
Jan 2019 – Present | Santa Clara, California, United States
* Led design and implementation of a SAML 2.0 authentication layer—tested with two enterprise IdPs and architected for any standards‑compliant provider—centralizing login across all data services and enabling customers to enforce corporate SSO.
* Built and launched an embedded Docker registry in the control plane, used by 100+ PoC customers to achieve plug‑and‑play deployments without any pre‑setup.
* Drove critical/high CVE resolution within a 3‑week SLA, ensuring no overdue vulnerabilities and maintaining audit‑ready posture.
* Developed and delivered annual workshops for 70+ engineers across two time zones, cutting basic installation escalations by 30% and shifting support to higher‑level issues.
* Automated annual certificate rotation via in‑product scripts, eliminating ~5 monthly escalations and saving an estimated 60+ engineer‑hours per year.
* Coached two direct reports—one from new grad to staff engineer and another newly hired at staff level—through career planning, code reviews, and architectural deep dives.
* Contributed to a cluster‑wide operator for immediate cert revocation via Cert‑Manager’s ClusterIssuer, strengthening compliance by automating CA‑driven revocations.

### Software Engineer 2 @ Dell EMC
Jan 2016 – Jan 2019 | San Francisco, California
Currently part of DellEMC object storage platform called Elastic Cloud Storage(ECS). Principally focused around distributed systems, HDFS and S3 object heads. Programming language used is Java.
 - Added support for Extended ACLs in our Object Storage Platform for hdfs requests.
 - Create background threads to provide the feature of blacklisting faulty nodes in an ECS server cluster by constantly pinging the agent status running on these nodes. 
- Identify and resolve resource leaks in our object storage while running complex Hive queries against it. 
 - Address critical bugs in Hive, HBase, HDFS services for Hadoop to certify ECS integration with Hortonworks' Ambari.
- Improved the overall passing percentage for tests certifying ECS to be compatible with Horton Dataworks Platform by resolving critical bugs relating to HDFS, Hive, HBase, YARN.
