Germantown, Md, Us

Led an enterprise-wide big data initiative by architecting, deploying, and maintaining an on-prem, HA configured Hadoop cluster and developing a replacement ETL pipeline in Java and Python. 1B records per day from 120 different schema are normalized, converted to Avro, and written to partitioned Hive tables.Architected, deployed, and maintain an on-prem, SSL enabled, Kerberized Kafka cluster. Designed and developed an automated system for deploying and maintaining the cluster in Python. Implemented a monitoring and alerting system with Datadog and EM7. Developed a Kafka Java SDK for consumers and producers that abstracts the configuration of a Kerberized client connecting to Kafka over SSL.Developed a generic Kafka-to-HDFSWriter Java library to read from a topic and append to files on HDFS which enables the persistence of streaming data for analytics and solves the Hadoop “small file” problem.Spearheaded the adoption of agile methodologies for all of EchoStar/Hughes by architecting and developing a highly-available, DR enabled, Atlassian suite to include Jira, Confluence, and Bitbucket integrated with corporate AD for SSO. Developed an automated system for deploying and maintaining each of the clustered components with a combination of Ansible and Python.

Baltimore, Md, Us

Designed and developed a streaming email and chat ingest pipeline implemented with a combination of a custom Python Postfix content-filter, RabbitMQ, and a custom Java Elasticsearch plug-in.Lead teams on multiple high-profile projects. Worked with product owners, VP, and C-level management to plan and manage sprints, define user stories and acceptance criteria, and estimate and schedule tasks.Increased observability of production systems and enabled the ability to troubleshoot and optimize sub-systems by designing, developing, and deploying a standardized logging, metrics, and monitoring system that included log aggregation via rsyslog, Ganglia, and Nagios.

Washington, District Of Columbia, Us

Migrated the core surveillance query system to AWS EMR from on-prem, legacy Oracle, Netezza, and Greenplum enterprise RDBMS appliances by writing and revising complex, multi-staged, SQL queries as Hive HQL queries or custom Java MapReduce algorithms.Developed custom Hive UDFs and UDTFs in Java.Increased team productivity by developing custom tools in Java, Bash, and Perl. One of the tools enables a distributed diff on terabytes or more of data.

Columbia, Md, Us

Designed and wrote custom MapReduce jobs in Java running against a 1.6PB Hadoop cluster of approximately 3,000 cores. This involved Servlet development, protocol buffer design, MapReduce code, RDBMS schema design, and writing SQL stored procedures.Increased developer efficiency by creating a standard development environment for writing and testing MapReduce code for the core statistical analysis subsystem to include automated replication of a complete mirror of the production HDFS structure, RDBMS schema, and SQL stored procedures.Designed and developed an end-to-end solution for browser-based data collection which dynamically adapts at runtime to collect data. Implemented with a combination of JavaScript, Servlets, and custom back-end clusters of Java servers.Led the backend, Big Data team working directly with product managers, client facing teams, and VP level engineering stakeholders to groom the backlog, develop themes, epics, user stories, and tasks, and provide day-to-day sprint management.

Falls Church, Va, Us

Designed and developed a high-profile R&D project to ingest up to 500MB/sec of data into RDBMS and HDFS datastores and enable concurrent queries against that data at up to 200 queries/second which lead to the award of a $500M contract. Developed a observability platform with a combination of custom Java applications, JMS, and SWING to provide a real-time metrics dashboard for 120 servers. Developed high volume, multi-threaded data generators in Java, and multi-threaded, dynamic query generators in Java to execute up to 5,000 queries per second.Architected and developed a real-time, behavioral based, zero-day, malware detection framework designed to stop e-mail phishing attacks based on observed behavior of potential malware as opposed to binary hashes. Designed to scale and process email for over 100,000 email accounts. Developed a web based dashboard to provide real-time system status, metrics, and web based tools for malware analysis. Implemented with a JavaEE MVC system that featured a high-concurrency server-side layer and Javascript client-side components.

The mid 90s saw an explosion of design firms, programming shops, marketing firms, and hosting companies each providing services that businesses of all types needed. At that time, I was working for an early new media design firm which focused on multimedia development and web design. One of the biggest challenges that I saw facing our clients was figuring out how to coordinate the efforts of the the designers, programers, marketeers, and hosting companies that they needed to develop a solid brand and collateral materials, an effective marketing strategy, and a website that helped them communicate with existing clients while helping them grow their business.It was the desire to build a company that could provide all of those integrated services to its clients that inspired me to start Nuts & Bolts Interactive, Inc.During its 14 years in operation I managed and maintained all aspects of the business.NBI's client list included UUNET, Chase Manhattan Bank, AARP, The American Association of Medical Colleges, The Discovery Channel, and The University of Maryland.NBI developed one of the early outsourced, domain-email services for small businesses that included a web-based administration control-panel and a fully-featured web-mail client.I effectively managed stakeholders and customers to ensure project success during all stages of development: opportunity development and sales, requirements analysis, marketing plan development, strategic planning, prototyping and R&D, development and production, training and deployment, support, maintenance, and system upgrades.I developed highly sticky recurring revenue offerings that were affordable to deploy by co-developing an extensible, LAMP stack, web applications framework, formVista.I maximized flexibility and minimized customer response time by designing, building, and maintaining all Internet infrastructure: web/database/e-mail/DNS servers, routers, power backup, automated data backup and recovery systems.
