https://codeceleste.comSince 2017, Celeste Computing has delivered high-quality software solutions at affordable prices.We’re a small, agile network of software engineers who strive to manage complexity, identify simple and straightforward engineering solutions, and provide maximal value to customers from the very beginning of the engagement.tools: elixir, phoenix/liveview, react, postgres, docker, linux, aws, mapbox, terraform

Conducted a cloud assessment for an Altran client with focus on reliability, security, scalability and cost. - Identified security gaps in AWS custom infrastructure and delivered recommendations for fixing vulnerabilities - Created a multi-tier approach to improve business continuity from monitoring to incident response to testing to development - Built code dependency graph visualizations in order to isolate potential points-of-failure in elixir applications. Tools: aws, terraform, phoenix, elixir, salt stack, erlang, postgresql, neo4j, elasticsearch, rabbitmq

Projects included Honeycomb with the Ingoma Foundation, a crowdsourced community asset-mapping tool. Nonprofit organizations in Baltimore operate in highly complex situational environments, without a clear citywide plan for supporting Baltimore's divested neighborhoods. These challenges inspired a tool for residents and nonprofits to collaborate in the creation of asset maps that connect people to the services they're looking for.Tools: phoenix, elixir, ecto, postgresql, postgis, react, aws, dockerOur next project was a machine learning analysis of economic text data. Thousands of documents were analyzed and catalogued via probabilistic topic modeling. A system was built consisting of a data ingestion + validation pipeline, job scheduler, job management database, model estimator and evaluator, graph-based metadata visualization, and API.Tools: java, maven, elasticsearch, elixir, phoenix, ecto, postgresql, neo4j, python, aws, docker

I revived a legacy project for managing public traffic video feeds on behalf of Departments of Transportation in multiple US states. - Improved the software development process by introducing a set of docker-backed web development environments. - Prototyped a video stream network visualization tool for internal use. - Balanced the implementation of new features, bug fixes, and infrastructure changes, given a rapidly changing set of software requirements.Tools: node, express, babel, webpack, mongodb, angular 2.x, docker, jenkins, git

Formerly RJMetrics- Implemented RJQL, a graphql-like query language for requesting data to power different visualizations on the analytics dashboard. Language features included a recursive formula parser, cohort analysis, data filters, and aggregation over time intervals- Wrote key Angular directives and services for saving, editing, resizing, and visualizing charts in The BI Report Builder 2.0- Developed database migrations and schemas to convert millions of legacy data objects to an RJQL-appropriate formatTools: php, backbone, RJMetrics, coffeescript, mysql, angular 1.x

- Designed and implemented software modules for analyzing and visualizing customer cohort data- Created an admin panel that allowed companies to run data analysis jobs on sampled data subsets
