David Lago

Full-Stack Product Builder · AI Agents, Web Apps & Developer Tools

I’m a full-stack developer and independent builder who enjoys creating products from scratch and integrating AI where it genuinely improves the workflow. I build web apps, AI agents, APIs, developer tools, database products and automation, working across frontend, backend and integrations. I especially enjoy turning ideas into useful, production-ready tools and finding practical ways to make AI part of the product instead of just adding it as a feature.

LakeDB — supporting Proof of Work image 2 by David Lago

Build· 2026

LakeDB

Built and shipped a cross-platform SQL client with multi-database workflows and review-first AI for SQL generation and query correction.

The context: Database workflows often get fragmented across different clients, connections and engines. I wanted one workspace that could keep connection context isolated, support real database operations, and add AI assistance without giving an agent permission to execute SQL automatically.
What was shipped: I built LakeDB as a desktop SQL client for MySQL, MariaDB and SQLite. It includes independent workspaces per connection, schema-aware SQL editing, table browsing and editing, database comparison and reviewable migrations, production safeguards, and QuerIA for context-aware SQL generation and AI-assisted query correction.
Operator contribution: I designed and built LakeDB mostly solo, including the desktop architecture, database integrations, SQL workflows, QuerIA integration, backend/API communication, privacy and execution boundaries, packaging/releases, and an enterprise deployment model where companies can control their own AI configuration and API infrastructure.
