Core software engineering competencies
| Type of problem |
Example of work |
| Concurrency |
Designed criteria for triggering interdependent database processing operation
Designed and implemented a log processor program that can be run in many instances allowing for trivial scaling
|
| Transactions and persistence |
Autonomous transactions to commit error records in case a work item failed and was rolled back
Large updates (150k rows) that needed to be committed in chunks and available to be reversed by another update as if rolled back
|
| Control |
Designed a system for controlling the parameters of advertising campaigns to achieve their best performance - both simple and optimal control
Designed a flow control system that allowed for media data to be sent in a low-priority channel over the same link as high priority data
|
| Data modeling |
Insists on verbalizing the nature of relationships between entities driving toward schema normalization.
Designed a data model change that simply captured history of changes to the data by adding time attributes to certain entities and forbidding their deletion |
| Application structure |
Familiar with Volatility-Based-Decomposition (VBD). Fan of Domain Driven Design (DDD).
Experienced with microservices and cloud deployments.
|
| Communication |
Formalization of the Graphon RapidX display protocol and wrote complex code for optimal transmission of graphical quantities
Designed the layered communication protocol system and the server side use of that system
