Own backend microservices and AWS infrastructure for member-facing healthcare APIs at scale — FHIR R4 REST APIs translating legacy claims and eligibility into HL7 resources for the mobile app, including serialization, bundle pagination, and versioned profiles
Built a Golang-based PII/PHI masking layer in API Gateway that redacts sensitive fields (SSNs, diagnosis codes, insurance IDs) before responses reach clients, aligned with HIPAA minimum-necessary practice
Design and operate serverless claims processing on AWS — Lambda sizing, DynamoDB access patterns, SQS dead-letter queues, API Gateway throttling — with Terraform and CloudFormation and least-privilege IAM across environments
Implement and maintain Pega BPM decision tables for adjudication and claim routing so business teams can update rules independently
Lead production incident triage with Splunk across Lambda, RDS, and API Gateway; diagnosed connection pool exhaustion and DynamoDB hot partitions, cutting member login 5xx rate from 3.2% to under 0.5% over two sprint cycles
Collaborate across product, compliance, and engineering in SAFe Agile delivery, including architecture reviews with a distributed team across time zones

Shipped backend features for a live J2EE SaaS product using layered MVC, from database through API, within Agile sprints
Designed a YAML-to-table JDBC data access layer replacing per-entity DAO boilerplate across 14 entities, standardizing CRUD and shortening feature delivery
Built authentication and session management: BCrypt (work factor 12), OTP-based 2FA via JavaMail with configurable SMTP TLS, and idle timeout expiry for a multi-tenant production product
Improved MySQL performance by removing N+1 patterns in high-traffic modules in favor of indexed JOINs — page loads dropped from about 4.8s to under 200ms on realistic data
