some stuff i've made:

Autonomous flash-loan arbitrage engine on Arbitrum. Detects DEX price discrepancies via the sequencer feed, simulates profitability with revm, and executes atomically via Balancer V2. Zero capital at risk.

A production-grade LSM-tree storage engine written from scratch in C. Features Write-Ahead Logging (WAL) for durability, Leveled Compaction, and Snapshot Isolation (MVCC).

A high-performance, event-driven Ethereum mempool monitor. Uses a custom parallel worker pool to overcome RPC latency limits.

A high-fidelity implementation of the Ethereum Modified Merkle Patricia Trie. Features deterministic state root generation, RLP serialization, and Merkle Proof verification.

A multithreaded, in-memory kv store implementing the RESP protocol. Leveraging Tokio and DashMap for fine-grained locking to handle high-concurrency workloads.

A security-focused HD Wallet generator in Rust. Implements 'Scorched Earth' memory hygiene (zeroize) to prevent cold-boot attacks and SLIP-0010 for full Phantom/Solflare interoperability.

A distributed SQL database providing Strong Consistency (CP) via Raft consensus. Decouples storage (SQLite WAL) from interface (Postgres Wire Protocol).

A decentralized, offline-first mesh network using Delay Tolerant Networking (DTN). Uses custom UDP Multicast Gossip and Curve25519 encryption for partition-resilient comms.

A distributed container orchestrator built from scratch. Collapses the control plane into a single binary using Raft for consensus and Lifeguard-enhanced gossip for failure detection.

An ephemeral database proxy that intercepts PostgreSQL wire protocol to instantly fork databases for every feature branch using filesystem-level Copy-on-Write.

A stateless, self-hosted remote build cache for monorepos. Decouples caching logic from storage to ensure data sovereignty.

A distributed cron-like scheduler in Go with Redis-backed leader election, consistent hashing for task placement, and Prometheus instrumentation across worker nodes.

An async-first webhook delivery platform built with FastAPI, Celery, Redis, and Postgres. Fans out events to subscribers with signed payloads, retries, and per-delivery visibility.

A production-grade BullMQ worker system with priority queues, scheduled jobs, exponential backoff retries, dead-letter queues, and a real-time operations dashboard.

A Redis-backed rate limiting service exposing configurable rules per API key, with atomic Lua-based token bucket and sliding window algorithms plus Prometheus metrics.
