Implemented a FUSE-based hybrid file system (ext4 and S3). 
Files beyond a certain threshold size were moved to the cloud.
Implemented deduplication and caching for file storage blocks.

CloudFS

Developed a simulation engine for the RAFT consensus algorithm leveraging RPC mechanism.
Handled leader election, server state replication, and consensus to withstand failures and network partitions.

RAFT: Consensus Algorithm

Implemented flash translation layer for SSDs translating logical block addresses to physical addresses. Implemented garbage collection and wear leveling owing to the asymmetry in SSD reads/writes/erases.

Flash Translation Layer for SSDs

Benchmarked HTTP/3 server implementations to identify the performance gains of individual features in the QUIC specification.

Comparative study of HTTP2 and HTTP3 web performance

Designed and implemented a multi-threaded HTTP proxy server in C with an LRU cache via Readers-Writers lock for consistency.

HTTP Web Proxy Server

Stragglers are slow-running tasks in the Distributed Computing Environment.
Studied various approaches to attenuate the impact of Stragglers on the overall Computation time.
Worked under a guide and presented a Seminar on The Review and Analysis of Straggler Mitigation Techniques.

Straggler Mitigation Techniques

Implemented a dynamic memory allocation library consisting of malloc, realloc, and free functions to manage heap memory.
Achieved high utilization and high throughput via footer-less segregated free lists and coalescing.
