I work on Striff, which checks every pull request against the architecture documents already in the repository. Before that, a decade designing production AI platforms across enterprise-scale organizations and startups: data pipelines, model training and evaluation, serving infrastructure, observability and cloud architecture.
Clarpse is a multi-language source code analysis library that extracts the structural relationships in a codebase (classes, methods, fields, imports and their connections) behind a language-agnostic API, so tools like jump-to-definition and find-usages need no per-language reimplementation.

Tokenization, stemming and relevance ranking behave differently in Arabic and English. This post documents a multilingual search system on Elasticsearch: index configuration, language-specific analyzers, query strategies, and how mixed-language queries were handled at the application layer.
The Google Closure Compiler minifies JavaScript, and its internals include a full AST parser. This post shows how to use it as a JavaScript parsing backend from Java for dependency analysis, code quality checks and refactoring tools, without writing a parser.
A performance comparison of IBM Bluemix PaaS instances and IBM Containers under equivalent workloads: response time, throughput, startup latency and resource use. The cold-start and sustained-load results differ enough to decide which model fits a given application.
Tables specify what a safety-critical system should output for each class of input, and tooling to verify them has been thin. Tabster is a Java library that checks properties of tabular expressions with SMT solvers and returns a counterexample for each one...
