v1: Microsevices and Socket Programming

Developed a crossword puzzle game using a Microservices architectural style. Engineered a custom TCP/UDP communication protocol to coordinate game logic with a standalone Word Repository service.

v2: Distributed Objects (RMI)

Re-architected the system to utilize Java RMI, replacing manual socket handling with Distributed Objects. Implemented a stateful server capable of managing concurrent sessions and multi-player game stems through synchronized remote methods.

v3: Fault Tolerance and At-Most-Once Semantics

Augmented the RMI infrastructure with a Failure Detector using heartbeat monitoring to track ALIVE, SUSPECTED, and FAILED client states. Engineered At-Most-Once semantics through request deduplication and sequence numbering to ensure idempotent server behavior.

v4 Peer-to-Peer and Consensus

Transitioned to a Peer-to-Peer (P2P) architecture using a Replicated State Machine model. Implemented FIFO-Total Order Broadcast powered by Lamport Logical Clocks and priority queues to maintain absolute consistency across all player replicas.

A gallery of the various CAD models I have created over the years.

Drill Animation

Modeled and animated a drill in SOLIDWORKS, based on the designs of a third party.

Unreal Engine Animation

Using premade models I created a living room environment and rendered an animation.
