We design and ship AI-ready web & mobile platforms - SaaS, marketplaces and internal tools - using JavaScript/TypeScript (React, Next.js, Vue, Nuxt, Angular), Node.js/NestJS and Laravel/PHP, with automation on n8n and Node-RED.
What we do
We help founders and product/ops teams build and grow:
* B2B SaaS platforms and multi-tenant products * Marketplaces & booking platforms * Internal tools, admin portals & back-office systems * AI-powered workflows, agents & chatbots around your existing tools * Apps that sit on top of solid APIs - from first MVP to production and long-term evolution.
How we start
Most problems are not in the code - they come from unclear scope. We usually begin with a short discovery phase on Upwork to:
* clarify goals, users and constraints * map key flows and data models * propose architecture and tech choices * define milestones, responsibilities and risks You get a clear, realistic plan before any serious development starts.
How we work during the project
* Break work into milestones with visible progress * Keep architecture clean and extensible (no quick hacks that become expensive later) * Ship early usable versions, not “big bang” releases at the end * Document APIs, flows and configs so your team isn’t locked out * Stay available for support, iterations and new features - not just “deliver and disappear”
We’re usually a good fit when you treat development as a product investment (MVP, new platform, major refactor), not a one-off $200 bugfix.
Where AI & automation fit in
We add AI and automation where they actually help, not “because it’s trendy”:
* n8n / Node-RED workflows to remove repetitive manual work * AI-powered outreach & campaign flows (emails, enrichment, routing) * AI agents and chatbots for support, onboarding and internal tools * Media & data pipelines: summaries, transcripts, tagging, reports * Search- and AI-ready data models from day one If automation doesn’t add ROI, we keep it simple.
