Skills

Computer Languages

Java 1.0/1.1/1.2/1.3/1.4/5.0/6.0/7/8/9/…/17

I have expertise with applications, applets, threads, networking, and reflection. I am an expert in the latest Java language features, such as typesafe enumerations, generics, streams, and lambdas. I have found and reported several core Java bugs including JDK-8218280, an off-by-one error in underlying line buffering I/O that had apparently existed for decades.

Extensible Markup Language (XML)

I implemented an XML processor from scratch directly from the XML specification. I constructed an XML-based persistence scheme for Java objects using Java reflection. I created XML schema parsers and CSS parsers from the W3C recommendations.

HTML/HTML5/XHTML/DHTML

I've co-authored markup languages, and have a philosophical insight into good markup design and rigorous separation between content and presentation.

C/C++

I've created and marketed entire applications written in C++. I developed a custom windowing toolkit from scratch. I created an object-oriented framework to wrap low-level TWAIN scanner access, as well as an object-oriented development kit for creating scanner drivers as TWAIN data sources.

JavaScript/ECMAScript

I've been intensely involved in JavaScript long before it was fashionable, creating entire Ajax frameworks before libraries like JQuery were available.

Other Languages and Formats

ObjectPascal (Delphi), 6502/6510 assembly, 80x86 assembly, Extensible Markup Language (XML), JavaScript Object Notation (JSON), Simple URF (SURF), Apache Avro, Google Protocol Buffers, Apache Thrift

Frameworks, Protocols, APIs, and Standards

JavaServer Faces (JSF)

I worked deep within the JSF reference implementation source code and submitted multiple bugs to Sun. I am the inventor of US Patent 20070016660 for a JavaServer Faces Upload technique.

Hypertext Transport Protocol (HTTP)

I created from scratch an implementation of HTTP directly from the specification, along with an implementation of the HTTP Digest authentication scheme for both client and server.

Web-based Distributed Authoring and Versioning (WebDAV)

This HTTP extension is the basis for Microsoft's WebFolders. I created from scratch a WebDAV servlet that allow custom authentication (using, for example, the HTTP digest authentication module I created).

Java Message Service (JMS)

I am familiar with the the JMS API, and in the past I created an implementation from scratch both on the server and on the client using SOAP as an underlying exchange syntax.

Session Initiation Protocol (SIP)

I created a SIP server and SIP stack from scratch for this HTTP-like VoIP signaling protocol made to replace H.323.

Java Swing

I've leveraged Swing to to its fullest extent, creating custom formatted text flowing views, many times researching into the Swing source code to find answers and submitting bug reports to Sun. I created an eBook reading platform which supports XHTML, pagination, and right-to-left languages such as Arabic and Urdu.

Resource Description Framework (RDF)

This metadata framework goes beyond mere descriptions to encode ontological assertions, allowing semantic-aware queries and inferences. I implemented an RDF processor from scratch, and I have a deep understanding of the propositional underpinnings of RDF and its relation to the semantic web.

Other Frameworks, Protocols, APIs, and Standards

Java Enterprise Edition / Jarkarta EE, Java Abstract Windowing Toolkit (AWT), Enterprise JavaBeans (EJB), Resource Description Framework (RDF), Cascading Syle Sheets (CSS), XML Document Object Model (DOM), XML Simple API for XML (SAX), XML Stylesheet Language (XSL), XML Namespaces, XML Schemas, XML Linking (XLink), XPointer/XPath, Active Server Pages (ASP), Java Server Pages (JSP), TCP/IP, UDP, Microsoft Foundation Classes (MFC), Borland ObjectWindows Library (OWL), Delphi Visual Component Library (VCL), Win32 API, TWAIN, C++ Standard Template Library (STL), COM/ActiveX, Unicode, MathML, Unified Software Development Process (USDP), Rational Unified Process (RUP), IMS Question & Test Interoperability Specification, IMS Content Packaging, Simple Object Access Protocol (SOAP), Spring

Cloud /Distributed Data

I am comfortable with a range of distributed data systems. I have added features to a proprietary, internal big data solution involving hashing and replication clusters.

Docker

Currently deploying Docker containerized services with CloudFormation and Amazon Elastic Container Registry (ECR).

Apache Hadoop

Rewrote core logic of a MapReduce project to allow efficient, multithreaded division of labor for processing a hierarchical data set. Wrote and published as open source a Java-native decorator class for Hadoop FileSystem to allow Spark usage on Windows without the need for third-party binaries.

Apache Kafka

Implemented data transformation and enrichment into Apache Avro for a pipeline siphoning payloads into a data lake.

Apache Spark

Configured, tested, and provided architectural review of a Scala-based Spark application meant to replace an existing MapReduce application.

Apache Thrift

Interfaced with a Thrift-based RPC mechanism for enriching data as part of a Kafka pipeline. Within days of looking at the Thrift source code, I reported and fixed bug THRIFT-4857 in which a core Thrift class validated Java consistency rules for hash code and equality.

Google Protocol Buffers

Added features to an existing project using protocol buffers both for RPC and also as a general serialization mechanism.

Apache ZooKeeper

Hands-on design and programming experience with a ZooKeeper deployment providing state for all the nodes in their big data system.

Cloud

Amazon Web Services (AWS)

I wrote the Guise™ Mummy static site generator from nothing, including automatic deployment to AWS: Route53 DNS routing to a CloudFront distribution using AWS Certificate Manager SSL/TLS certificates for multiple S3 buckets, with apex domain support. Currently deploying VPCs, subnets, and Docker containerized services with Amazon Elastic Container Registry via CloudFormation.

Front-End

AngularJS

I led a two-year project using AngularJS on the front-end with custom LDAP authentication and data storage via a RESTful API data storage microservice. I've created nested, dynamic AngularJS with custom models.

Guise™ Framework and Ajax

Extremely dissatisfied with JSF, I created a comprehensive and elegant Internet application framework that handles asynchronous server communication and real-time component updates transparently. The entire framework component hierarchy is abstracted from the end-user technologies, without application developers to write any HTML or JavaScript. All Ajax functionality was written from scratch.

Communication and Interaction

I have excellent control of the English language, with the skills to write software documentation, prose, or poetry. I excel in education and teaching, working in environments in which I manage and/or educate groups or individuals. I work well as part of a group or alone. I interact well with others of diverse personalities and backgrounds. I apply skills of logical thinking, rational problem solving, and object-oriented design and analysis both to complete my work and to effectively function within the work environment.
