some stuff i've made
from systems-heavy builds to backend, cloud, and devops work.
Siphon // 16-service self-retraining ML loopsystems · ml · ai infra · backend · databaseA TikTok-shaped recommendation system: bots watch videos, every watch and skip streams back, and the ranking model retrains itself and only ships if it's measurably better.Engram // distributed Raft + ANN searchsystems · ai infra · backendA distributed memory backend for LLM agents: short-term messages, long-term vector search, pinned facts, auto-extracted knowledge graphs, and cross-session shared memory, all replicated across a Raft cluster.Sonar // proof in <200k compute unitssystems · blockchain · securityLets Solana apps prove a heavy calculation was done correctly off-chain, without redoing it.arbx // 17ns AMM calculation, 467us full market scansystems · backend · blockchainA bot that spots price gaps between crypto exchanges and trades them automatically for profit, using borrowed money it pays back in the same instant.Shadow-Index // 71k+ tx/sec throughputsystems · backend · blockchain · databaseReads and stores Ethereum's live activity the moment it happens, so apps can search it instantly.Lithos // 72k+ writes/sec & 97k+ reads/secsystems · databaseA from-scratch database storage engine that saves data fast and never loses it, even on a crash.Mempool-Sniper // <500ms Detection Latencysystems · backend · blockchainWatches Ethereum's queue of pending transactions and flags interesting ones in real time.Merkle-Trie-RS // O(1) State Verificationsystems · blockchainA from-scratch build of the data structure Ethereum uses to prove what's in its database.jchain // PoW + PoS from scratchsystems · blockchainA blockchain node built from scratch in Java: SHA-256 hashing, Merkle trees, PoW/PoS consensus, threaded mining, file and MySQL persistence, a CLI, and a live web dashboard.rusty-redis // ~1.4M+ ops/sec (Benchmarked)systems · backend · databaseA from-scratch clone of Redis, a super-fast in-memory store apps use as a cache.cold-cli // Zeroizes RAM on dropsecurity · blockchain · devtoolsA crypto wallet generator that wipes its own memory clean so secrets can't be stolen afterward.Aether // zero-downtime snapshotssystems · database · backendA database spread across many machines that stays correct and online even if some of them fail.CrisisMesh // guaranteed delivery, no internetsystems · networking · securityA messaging network that keeps working with no internet. phones relay messages directly, encrypted.Orion // Self-healing cluster in <2ssystems · cloud · devopsA from-scratch tool that runs and heals fleets of app containers across many servers automatically.Prism // Database branching in <300mssystems · database · devtoolsGives every developer their own instant copy of the database to test on, created in a fraction of a second.VelocityCache // 231x faster cache restore vs TurboRepocloud · devops · devtoolsA shared cache that skips rebuilding code you've already built, so big projects compile far faster.Distributed Task Scheduler // fault-tolerant, leader-electedsystems · backend · cloud · devopsRuns scheduled jobs reliably across many servers, splitting the work and surviving failures.Webhook Delivery Service // tamper-proof + guaranteed deliverybackend · cloud · devopsReliably notifies other apps when something happens, with retries and tamper-proof signatures.Job Queue & Worker System // priority lanes + dead letter queuebackend · cloud · devopsRuns background jobs in priority order with retries and a live dashboard to watch them.Rate Limiter as a Service // atomic, per-user rate limitingbackend · cloud · devopsCaps how often each user can hit an API, to stop abuse and overload.
