Production Projects
elekcsv
High-performance, headless, locale-aware CSV data ingestion and validation toolkit. Unifies parsing, fuzzy column mapping, and validation into a single pass. Compiles schemas into optimized raw V8 JavaScript functions (new Function()) and utilizes dense bitmasks for O(1) cell error lookups, eliminating Garbage Collector (GC) thrashing on 100k+ row browser imports.
Grafana
Universal observability platform; Go backend queries disparate time-series databases and streams real-time telemetry to customizable React panels.
Mattermost
High-security enterprise messaging; Go backend with concurrent WebSocket routing and React desktop/web clients.
Rocket.Chat
Enterprise privacy-first Slack alternative; combines real-time messaging, WebRTC video calling, matrix federation, and strict compliance security with full on-premises data ownership.
Hasura
Turns databases into high-throughput GraphQL APIs in seconds; compiles GraphQL queries directly into optimized single-query SQL statements in Haskell with enterprise access controls.
Payload CMS
The modern standard for headless content management; runs completely natively inside Next.js with Drizzle ORM and React Server Components, offering zero-latency Local API calls.
tRPC
Eliminates API schema drift without code generation; TypeScript compiles client and server code together to infer procedure input, output, and error types automatically.
Prisma
Benchmark developer experience for relational databases; leverages declarative schema modeling to auto-generate fully type-safe TypeScript clients backed by an optimized query engine.
Deno
Modern secure runtime by Ryan Dahl; eliminates node_modules and build pipelines with first-class TypeScript, web standard APIs, and an explicit capability-based security sandbox.
Astro
Content-driven web framework pioneering the Islands Architecture; ships pure semantic HTML by default, selectively hydrating interactive UI components only when visible in viewport.
n8n
Leading self-hosted Zapier alternative; combines an intuitive Vue visual canvas with a high-throughput Node.js execution engine and built-in AI agent reasoning nodes.
LangChain
Industry standard for context-aware reasoning; modular chains and LangGraph cyclic graphs allow orchestrating stateful agents with deterministic fallbacks and tool execution.
shadcn/ui
Paradigm shift in design systems; developers own component code directly in their repository without node_modules abstraction lock-in, pairing Radix accessibility with Tailwind.
Bun
Radical reimagining of JS tooling; written from scratch in Zig on WebKit JavaScriptCore for 4x faster module resolution, zero-transpilation TypeScript, and native SQLite speed.
Tailwind CSS
Industry-standard utility styling; modern v4 rewrites the core engine in Rust (Oxide) to scan gigabytes of project files and compile CSS in microsecond render cycles.
Next.js
The enterprise React benchmark; leverages React Server Components, server actions, and a high-performance Rust compiler (Turbopack) for maximum SEO and sub-second page loads.
PostGraphile
Compiles PostgreSQL database schemas, functions, and Row-Level Security (RLS) policies into an instant, high-performance GraphQL API without N+1 query overhead. Generates optimized single-query SQL execution plans directly from incoming GraphQL ASTs.
LibreChat
Self-hosted AI conversation and autonomous agent workspace supporting all major LLMs (OpenAI, Anthropic, Ollama, HuggingFace). Built with Node.js Express, MongoDB for flexible conversation trees, Redis for rate limiting and streaming buffers, and a responsive React UI.
Fasten Health
Self-hosted personal health record aggregator connecting thousands of medical institutions via standard SMART-on-FHIR protocols. Built in Go for secure single-binary local-first deployment with embedded encrypted SQLite storage and zero third-party telemetry.
Refine
Headless React framework designed for rapid development of enterprise internal panels, admin dashboards, and B2B CRUD applications. Decouples business logic, access control (RBAC), and server-state caching (TanStack Query) from UI design system adapters.
Browserless
Production-grade headless browser grid for automated web scraping, PDF generation, and synthetic testing. Wraps Chromium instances in isolated Docker sandboxes with WebSocket multiplexing, connection pooling, and memory-leak auto-restarts.
Apache Answer
Self-hosted developer community and technical Q&A platform (Stack Overflow / Dev Community alternative). Built with Go Gin for high concurrency and low memory usage, GORM for multi-database persistence (Postgres/MySQL/SQLite), and React TypeScript for rich Markdown editing.
Temporal
Durable execution platform allowing developers to write resilient, long-running distributed workflows in code without worrying about network partitions, crashes, or server restarts. Backed by Go gRPC cluster nodes and persistent event-history replay logs in PostgreSQL/Cassandra.
Cosmo (WunderGraph)
Open-source GraphQL federation gateway and router written in Go. Compiles subgraphs into unified declarative execution plans with sub-millisecond routing overhead, zero-allocation request pipelines, OTEL distributed tracing, and ClickHouse-backed analytics.
