Picking up where we left off at IEX Cloud, working with a small startup to launch a financial services platform that will encapsulate the data sets and services API offered by IEX prior to shutting down the division. Using the same technology, I am working on the backend services like realtime and delayed feeds, using Java, Redis, Kafka, with a little Go thrown in. Parsing realtime and delayed exchange data feeds for customer consumption using low-level Java and multithreading with nio packages, LMAX disruptor, sockets, etc.

Back-end (full-stack) SDE, cloud-based financial product services in the IEXCloud division.I was brought onboard to lead a migration of the legacy cloud miroservices from a node.js/cassandra/Java infrastructure to a new one using Scylla db/Golang in order to increase speed and reduce footprint. However, the IExCloud division of IEx was dissolved in June 2024 in order to narrow focus and better align with the core business.Accomplishments:• Parsing new raw binary streams of market data for ingestion by existing microservices framed with Kafka, Redis, and Apache Airflow using Java/Python. • Created infrastructure in Java to cache and reconstitute the daily transaction records in the event of an outage. • Initial architecture and design for migrating to Go/ScyllaDB.

Back-end (full-stack) SDE, Oracle Cloud Infrastructure (OCI) IaaS. This is Oracle's cloud infrastructure offering, competing against AWS/Azure/GCP. All services were highly distributed and fully integrated with IAM, storage, secrets, auditing, load balancing, metrics, monitoring, etc. Services were developed with the principals of scalability, availability, and reliability in mind. These positions presented a rare opportunity to work on the other side of a cloud services provider.Developers were also responsible for all non-UI stages of the SDLC for their services including writing/testing/debugging, packaging (Docker) and deployment (TerraForm-templated) to Kubernetes clusters running Oracle Linux in virtual environments.Highlighted achievements:• As part of the threat intelligence service team, created a service written in Go to ingest TOR exit node data for context processing. • Also created a STIX 2.1-formatted IoC framework for internal customer SIEM consumption using Go. • As part of the messaging team, I was technical lead for a REST API-based configuration module (control plane), including API design and implementation using OpenAPI Swagger, Java.• Created tools to assist with automation using Python.

Back-end SDE as part of the cloud team that designed and created a new provisioning system for deploying and managing containerized RSA IAM applications using Microsoft Azure, JSP, Java, VMWare, ELK stack, along with RabbitMQ as the message broker.Highlighted achievements:• Created infrastructure to allow the operator/user to select only available and compatible software versions to be deployed as part of the pod. • Worked with the iOS/Android apps for the IAM product.

Sr. Staff Engineer for the SAP Mobile Platform. Worked on a new, Eclipse-based designer/generator used to create cross-platform, hybrid mobile web applications. Extensive use of Java, JavaScript, jQuery Mobile, HTML5/CSS and other web technologies. This product represented a “write once, deploy anywhere” paradigm used to create hybrid mobile applications. Prototype work in node.js cloud-based development environment.• Features in many areas such as on-device caching, JavaScript generation, data display via HTML DOM.• Scrum master and team leader over 2 releases.

Engaged as a staff level developer and manager in the architecture and implementation of features on the product. Managed a team of 5 senior C++/C# developers through major release as well as several minor releases of a popular client-server development tool.• Delivered a fully rewritten, reliable visual development tool for a large customer base, allowing the customer base to write applications running on a more mainstream platform (C++ and .NET applications).• Designed and implemented a visual menu designer allowing customers to create fully customized, scripted menus for their applications.

Small, focused team creating mobile client-server tool built in C++ based on desktop application product; helped provide vision• Enhanced capability of the customer by creating a framework allowing the developer the ability to control the behavior of the SIP (Window CE software keyboard) for applications built with PK VM.• Designed and implemented features allowing developers the ability to create custom notifications on the home screen of the Windows CE device, providing a new marketing feature and culminating in early product release.

Database interaction with an XML-driven, J2EE vertical market solution for the telecommunications industry. Facilitated interaction between the application and the Sybase ASE database, as well as the XML query language definition in this newly created product.• Created XML-based SQL query engine using Java.• Coordinated database schema integrity between CeBS and EHPT (Ericsson / Hewlett Packard Telecommunications) Oracle back end database, ensuring mapping was complete with minimal redundancy and resulting in accurate and efficient information exchange.

Core C++ work (Windows SDK) on Sybase PowerBuilder IDE.
