FIRST CITIZENS BANK, Los Angeles, CA

Senior Full Stack Developer Apr 2024 to Present

● Built React and Redux screens for account dashboards, funds transfer, and transaction history that retail banking customers use every day.

● Introduced a shared component library in React so balance displays, transfer confirmations, and account summaries stayed visually consistent across the platform.

● Built a React based case review screen that lets compliance analysts triage flagged transactions quickly, with filtering and sorting tuned to how the team actually works.

● Wrote Jest coverage for the transfer confirmation flow so UI regressions get caught before they reach customers.

● Built Python microservices on Django REST Framework to power account management, funds transfer, and transaction history APIs.

● Designed the fraud review workflow, where Python services score incoming transactions for risk and route flagged cases into a queue for compliance analysts.

● Set up Celery workers consuming Kafka topics to process payment confirmations and account notifications without blocking the customer facing request path.

● Added field level encryption and masking to backend services handling account numbers and personal data to meet banking data protection requirements.

● Wrote nightly Python reconciliation jobs comparing application level transaction totals against Oracle ledger balances, catching mismatches ahead of settlement close.

● Rewrote several Oracle stored procedures feeding the finance team's daily reports, bringing report generation time down noticeably during peak load.

● Migrated the transaction processing service onto AWS EKS, running it in Docker and Kubernetes with CloudWatch dashboards tracking latency and error spikes.

● Set up a Jenkins pipeline running PyTest and Jest suites automatically before anything reaches the production banking environment.

Full Stack Developer Jun 2022 to Mar 2024

● Rebuilt the appointment scheduling calendar in React, replacing a legacy screen that front desk staff across several clinics found slow and confusing.

● Built a patient facing intake form in React with inline validation to cut down on incomplete submissions before appointments.

● Developed reusable UI components in JavaScript and CSS3 for provider availability views and telemedicine session screens.

● Worked closely with clinical staff to translate paper based intake processes into structured, easy to use digital workflows.

● Wrote the Flask services behind patient intake and provider availability lookups, including the logic that prevents double booking across overlapping provider schedules.

● Built mapping scripts that translate patient records between HL7 and FHIR style formats from different clinical source systems into one consistent internal schema.

● Streamed telemedicine session start and end events through Kafka so the provider notification service could alert staff in near real time.

● Set up automated email and SMS reminder triggers tied to the scheduling service to reduce no show rates.

● Put together data validation checks in Python that catch incomplete patient records, such as missing insurance IDs or malformed dates of birth, before they reach billing.

● Designed the PostgreSQL and Oracle schemas for visit history and insurance eligibility, tuned for the scheduling screen's most frequent queries.

● Ran weekly Pandas based reporting jobs summarizing clinic utilization and no show rates for practice administrators.

● Containerized the Flask services with Docker for AWS deployment and worked with infrastructure on the access controls required for HIPAA compliance.

● Built the backend service that persisted wishlist selections per customer account, including server side validation on the checkout path.

● Built a lightweight Python service that fed browsing and purchase history signals to the personalization team's recommendation models.

● Used Kafka producers and consumers to keep inventory counts consistent across warehouse, store, and online channels, which mattered most during flash sales.

● Wrote Pandas based ETL jobs pulling daily sales and inventory numbers from store point of sale systems into the central reporting warehouse.

● Tracked down and fixed slow MySQL and Oracle queries in the order management path that were adding seconds to checkout during peak traffic.

● Built scheduled jobs comparing online and in store inventory counts and alerting the operations team when they drifted out of sync.
