• Leads a team of 4 developers in migrating security risks before reaching service-level agreements • Writes secure and performative code for product launches and improvements to existing products • Collaborates with engineers and developers on the design and road mapping of complex projects • Communicates with frontend engineers to create APIs to provide an optimal experience for users • Partners with external teams to produce security applications and larger scale development tools • Contributes to cross-functional development of contracts and protocols for system communications • Participates in daily stand-ups, weekly meetings, and biweekly retros as a subject matter expert • Presents new products, development successes, and impact reports to the senior leadership team • Creates mechanisms to mitigate, address, and accept security measures while testing for vulnerabilities • Writes code for an application to ingest Prime Video’s metadata, transforming it into more usable data • Improves searchability, findability, and recommendations by unifying Prime Video data• Contributes to important architectural and operational decisions, including microservices, monoliths, deployment techniques, technologies, policies, and processes for customer experiences and security Key Accomplishments: • Provided build tool integration for one of Amazon’s main security products, which improves developer time by 2 hours when testing on applications, reduces bugs by an estimated 20%, and is expected to reduce costs by programmatically testing simulated real world network patterns • Successfully designed up to 40% of the team’s current product and implemented 20% of the product, designing the core engine and redesigning the storage system for an internal data owner for Prime • Partnered with a team to update and redeploy 90% of Java applications in 2 days to harden infrastructure against the vulnerability of a java deserialization, protecting Amazon from a major threat

• Spearheaded efforts to replace an infrastructure maintenance tool for a higher capacity resource • Assisted with the move from a microservice structure to a more traditional segmented mainframe and monolithic structure, streamlining 60 applications into a singular, multi-faceted application • Served as the subject matter expert on the previous code’s actions, offering valuable insight to a team of 6 developers and a programming team when replicating the code to design a new program • Implemented backend programming designs while utilizing in-depth knowledge of code logic • Utilized Python to create test files of clean data in compliance with bank information security standards, along with a suite of tools to generate and run tests, facilitating functionality of the new implementations • Managed file transformation, parsing, and responsive scaling, ensuring documents received could be properly parsed and stored for future use and record keeping according to sensitive data policies• Worked with Pyspark, AWS, and SQL to deliver streamed partner data for customer acquisition Key Accomplishments: • Successfully streamlined maintenance processes, which improved amount of infrastructure and server space needed for operations by 80%, producing an 80% cost reduction with $5M+ annual savings • Heavily contributed to the design, development, and implementation of an application to process and serve customer statements with the ability to respond to 3,000+ requests per hour • Owned the replacement of an infrastructure maintenance tool, effectively reducing maintenance time from 160 hours per week to 4 hours per week by building a more simplified and streamlined system

• Developed proof-of-concept security exploits to infiltrate undefended attack surfaces and execute exploits against known security vulnerabilities in order to reallocate further policy and tooling resources • Designed and developed security policies that mitigated an Apache Tomcat vulnerability and a Java Deserialization vulnerability discovered through in-depth testing on possible security attacks • Utilized MS Excel to write Malware and prove the need for heightened technical security measures • Assembled detailed presentations for the Chief Security Officer on recommendations for security policy changes, additional employee training, new scanning tools, and measures available to improve security Key Accomplishments: • Successfully increased overall technical security to at least 75% against specific vulnerabilities uncovered, resulting in the prevention of root control of arbitrary computers within Alliant Energy • Spearheaded testing efforts that targeted the financial department to identify vulnerabilities, and then wrote effective trainings for employees to understand threats, prevent loss of money, secure financial departments, and protect overall service power access across 5+ states to nearly 1M customers

• Managed efforts to improve data acquisition processes for auditing, combining data acquisition paths for PCI and SOC 2 reports by mapping internal controls and automating parts of the process • Functioned as a subject matter expert in data collection and interpretation for security audits • Created a roadmap between SOC 2 and PCI to expedite data delivery to internal and external teams • Developed data mapping strategies that were extended throughout the organization for other audits Key Accomplishments: • Significantly improved the data acquisition processes through automation and consolidation, resulting in the reduction of human interaction by over 50% and increased data accuracy by at least 150%
