Playground

Built at 3 a.m., mostly on purpose

Systems, agents, and tools I built to see if I could. Distributed infra, multi-agent platforms, computer vision, and a bit of chaos. Most are open source.

AgentsSynapseGraphA multi-agent platform that writes a full company research report on demand: eight LangGraph nodes over FastAPI, four analysts gathering sources in parallel, streamed node by node over WebSocket. Gemini 2.0 Flash synthesizes; GPT-4.1-mini formats.
SystemsDistributed ML PlatformReal-time IoT analytics: Kafka into Spark Structured Streaming running three ML models in parallel, results in Elasticsearch for a live Kibana dashboard. A 4-node, 32-core cluster sustains 700+ msg/s, under 300ms end to end.
SystemsReverse Proxy from scratchNo NGINX, no Traefik. A reverse proxy built from the ground up: a Node.js cluster with self-healing workers, YAML-driven routing, round-robin load balancing, health checks, and Redis-backed caching + rate limiting.
CloudDistributed Web CrawlerDrop URLs into a React UI; they fan out through AWS SQS to containerized ECS Fargate workers, land in S3, and scale on queue depth, all watched by CloudWatch. Fully serverless, pay-per-use.
MLSAM for Scientific ChartsA synthetic-data generator for fine-tuning Segment Anything: programmatically renders jittered bar charts, volcano and Voronoi diagrams as paired RGB images + segmentation masks, with bounding boxes and point prompts.
MLSelf-Driving CarA neural network built from scratch, no ML libraries, that learns to follow lanes, dodge obstacles, and pick its way through intersections. A Canvas sim renders the network's decisions live.
ToolingAlgoScribeA React code editor that animates algorithms as they run. Write JavaScript; watch trees and data structures move. Built with CodeMirror, Firebase, and a custom renderer.
CVHandwritten Signature ExtractionBiometric signature analysis by recursive quadtree decomposition. Centroids, edge density, aspect ratios, and slant angles become stable features for verification and writer ID.
