• Programming (using Golang) the existing payment fraud detection system to interface with external platforms (including Cybersource, Forter, and Cardinal), accept transaction data from multiple sources (e.g. online, store terminal, and phone order), record metrics (for Grafana), and mask sensitive data.• Programming (using Golang and Java) the existing payment authorization system to successfully handle multiple encryption formats from PIN pad transactions for authorizations, reversals, and refunds. • Upgrading software in test and production environments (using GCP, PCF, Jenkins, Artifactory, etc.).• Resolving issues with card declines and errors in authorizations and reversals (using Google BigQuery, DBeaver, Grafana, Postman, etc.)

• Designed front-end features (using React and Angular) for applications used to create and compare insurance plans for multiple health-care providers (CRP - Client Requirements Portal, SPGR - Specialty Performance Guarantee Reporting, and Eligibility Workflow). • Coded back-end services (using Spring, Java, Python, SQL, and JSON) for aforementioned applications.

• Programmed back-end services (using Spring, Java, Hibernate, and SQL in deployed AWS Linux VM environments) for applications used to mitigate risks and enforce adherence to banking regulations (AML - Anti-Money Laundering, KYC - Know Your Customer, Compliance Assurance, and Risk Assessment).• Analyzed and evaluated design patterns, unit tests, and coding practices for micro-services to prioritize security and optimization.

• Designed and implemented an online e-commerce system (using Angular with REST and a back-end with Java, Spring, and MySQL) used by customers to make customized cake orders (with specifics on size, flavor, writing, delivery date, etc).• Scheduled and assigned tasks based on deadlines as well as employee experience and competency.• Managed staff ensuring proper communication, understanding, and execution of instructions.• Budgeted with accountants to create financial goals and project upcoming expenses.

• Designed and implemented an ETL process (using Java, XML, SQL, and shell scripts) for parsing through large sets of statement/ledger files and applying user-defined logic/functions, currency translation, mappings, queried values, and static values while streaming file data into a common format for automated reconciliation across multiple production environments (e.g. OTC Derivatives and Mutual Funds).• Maintained and supported vendor software for reconciliation and analysis, TLM (Transaction Lifecycle Management - a product of Smartstream Technologies), including troubleshooting user issues, modifying system configurations based on evolving business logic, and performing reboots, deployments, and migrations (using WebSphere and Linux).• Implemented multiple features (using Java Server Pages, Spring, and DB2) and performed deployments and migrations (using WebSphere) for several distributed applications used in trade processing (Federal Pledge and Release, Mutual Funds Reconciliation, Vault Certificate Recording, and SPOPPO - Securities Payment Orders - Premium Payment Orders).• Gained extensive banking knowledge through the Systems Rotational Training Program, a nine-month orientation into tech-finance with hand-on experience in multiple departments including Quality Management, Business Application Development, Trade Processing, Enterprise Systems Support, Information Security Management, and Project Management.

Department of Electrical Engineering and Computer Science, University of California, BerkeleyBuilt an IDE (integrated development environment) (using Java Swing) for a hardware/software verification system known as UCLID (Uninterpreted symbols, Counter arithmetic, and Lambda expressions for Infinite Domains) used to optimize error tracing for files through front-end components (error trace table, variable dependency trees, and variable queries).

College of Computing, Georgia Institute of TechnologyImplemented a user interface (using Java Swing) for Topaz, a peer-to-peer networking program created at Georgia Institute of Technology used to research network traversal through random walks (performed when an algorithm randomly selects adjacent nodes in a given network).
