What services does A Major offer?

A Major offers web design, web app development, mobile app development (React Native, Swift, Flutter), SaaS product development, enterprise systems, UI/UX design, DevOps, performance optimization, MCP server development, AI agent infrastructure, MVP scoping, digital transformation, and engineering consultancy.

Where is A Major based?

A Major is based in Singapore and works with clients worldwide.

Do you work with international clients?

Yes. While headquartered in Singapore, A Major works with founders and businesses across Southeast Asia, Europe, and North America.

Ryu is an AI agent orchestration layer built by A Major. It enables teams to run, coordinate, and monitor AI agents at scale — connecting LLMs, tools, and workflows into reliable production systems.

Do you build MCP servers?

Yes. A Major builds Model Context Protocol (MCP) servers that connect AI agents to databases, APIs, and internal tools, enabling reliable LLM-powered workflows in production environments.

How much does SQLite cost?

SQLite itself is public domain and completely free. Turso offers a free tier (500 databases, 9GB storage) with paid plans from $29/month. Cloudflare D1 has a free tier (5GB) with pay-as-you-go pricing after that.

SQLite vs PostgreSQL — when to use which?

Use SQLite for local-first apps, embedded databases, edge deployments, and development. Use PostgreSQL for complex relational queries, heavy write workloads, and applications requiring advanced features like RLS, full-text search, or pgvector.

Can SQLite handle production traffic?

Yes, with the right architecture. Turso and D1 serve production traffic at the edge with global replication. SQLite handles read-heavy workloads exceptionally well. For write-heavy workloads, ensure WAL mode is enabled and consider Turso's embedded replicas.

SQLite is the right choice for local-first apps, edge deployments, and development environments. With libSQL (Turso), it scales to global replication — serverless SQLite with zero cold starts.

SQLite is the most widely deployed database engine in the world — embedded in every smartphone, browser, and operating system. It's a zero-configuration, serverless, single-file SQL database that's perfect for local-first apps, edge deployments, and development environments. With libSQL (Turso) and Cloudflare D1, SQLite now scales to global replication with edge-local reads, branching, and zero cold starts. It's no longer just for prototyping — modern SQLite powers production workloads at the edge with sub-millisecond query latency.

Quick start

bash

# Install SQLite
brew install sqlite

# Or use Turso
curl -sSfL https://get.tur.so/install.sh | bash
turso db create myapp
turso db show myapp --url

# Or use Cloudflare D1
npx wrangler d1 create myapp

Zero dependencies

SQLite is a single file — no server process, no network, no configuration.

Turso edge deployment

libSQL and Turso replicate SQLite globally — read latency under 10ms from any region.

Local-first apps

Embed a full SQL database in Tauri desktop apps, mobile apps, or Electron — works offline by default.

Database branching

Turso's branching creates isolated database copies for each dev/staging environment.

Works with Drizzle & Prisma

First-class support in both Drizzle ORM and Prisma — your existing query code works unchanged.

Cloudflare D1

Deploy SQLite at the edge with Cloudflare D1 — co-located with your Workers for minimal latency.

Why it's hard

Write concurrency limitations

SQLite uses a single-writer model — concurrent writes are serialized. For write-heavy workloads, WAL mode and connection pooling help, but high write throughput may require a client-server database.

No built-in replication

Vanilla SQLite has no replication. Turso (libSQL) and Cloudflare D1 add global read replicas and edge distribution for production use cases that need it.

Migration tooling choices

SQLite migration workflows differ between Drizzle Kit, Prisma Migrate, and Wrangler (for D1). Pick one and standardise — mixing migration tools leads to schema drift.

Best practices

Enable WAL mode for concurrency

Write-Ahead Logging (PRAGMA journal_mode=WAL) allows concurrent reads during writes — essential for any multi-user application.

Use Turso for production edge deployment

Turso replicates SQLite globally with embedded replicas — each app instance gets a local copy with automatic sync.

Pair with Drizzle ORM for type safety

Drizzle's SQLite driver provides full TypeScript inference with zero overhead — your types match your schema exactly.
