Software Engineering Lead
Mar 2021 — Oct 2024
Lead a team of three software engineers in development and execution of innovative software solutions aimed at enhancing user experience. Build projects on microservices, data migration, Identity and Access Management, while reporting directly to Sr. Director. Implement best practices to streamline development processes, optimize coding workflows, and uphold rigorous quality assurance standards in compliance with industry regulations.
● Saved $2M annually, improved system reliability, and reduced operational overhead with minimal downtime by leading migration of ElasticSearch to AWS OpenSearch for patient services.
● Designed and implemented a resilient solution to address ProvisionedThroughputExceededException in our Master Data Management(MDM) pipeline that uses AWS Kinesis Streams to process patient data by splitting large files (greater than 250MB) and introducing exponential backoff with jitter, eliminating manual intervention and significantly improving system reliability and fault tolerance.
● Spearheaded successful migration of Outbound SSO from an outdated Keycloak version to PING Identity, enhancing security and eliminating vulnerabilities while overcoming challenges of joining mid-project with limited prior domain expertise.
● Enabled the team to focus on strategic initiatives and significantly boosted productivity within three months by spearheading automation/process improvements and reducing KTLO/BAU tasks from 40-50% to under 10%.
● Ensured seamless integration with Accolade’s identity platform by directing reloading of 2.3M PlushCare users into a new User Service format, addressing resistance by resolving core concerns, and mapping custom attributes to SCIM.
● Drove significant improvements in coding skills, personal development, and overall team productivity by coordinating regular one-on-one meetings with junior team members, while emphasizing technical growth, recommending resources, and pairing them with senior mentors.

quality code and optimized application performance by leveraging proficiency in various programming languages and frameworks. Collaborated with cross-functional teams to analyze user requirements and implement best practices in software development.
● Designed and developed HL7 FHIR-based Patient and Claims CRUD and search APIs to deliver MVP on time by gathering requirements and collaborating effectively with the team.
● Drove successful implementation of a new Master Data Management (MDM 2.0) pipeline using AWS services, aimed at eliminating undermatch issues, reducing overmatch occurrences to under 1%, and expediting patient access issue resolution.
● Delivered a robust solution for ClusterIndexWriteBlockedException by reconfiguring Elasticsearch shards for balanced distribution across nodes, restoring patient search functionality, improving reliability, and adding proactive disk space alerts.
● Ensured continuous service availability and prevented future disruptions by identifying and resolving a memory leak in Patient Service APIs through development of a Lambda function for automatic instance restarts.
● Restored critical patient search functionality and minimized business disruption by resolving a Severity 1 incident within one hour diagnosing high CPU usage from wildcard queries(DDOS) and coordinating with AWS to restart Elasticsearch nodes.
