## About

Onpolar is the senior product engineering partner companies hire when they need real software shipped — not slide decks, not pilots that die in prototype. We own the full stack: architecture, backend, frontend, infrastructure and the AI layer.

WHAT WE BUILD

AI-Native SaaS — multi-tenant products with agentic workflows, permission-aware context, billing and compliance- Full-Stack Product Engineering — landing page to multilingual platform, MVP to production scale- Generative Engine Optimization (GEO) — get cited by ChatGPT, Claude, Perplexity and Gemini as traditional SEO bleeds clicks- Big Data & ETL Pipelines — public datasets, CRM exports and event streams into reliable product surfaces- Vibe Code Rescue — Lovable, Bolt, v0 and Cursor prototypes refactored into modular, type-safe, tested production architecture

WE BUILD AND OPERATE OUR OWN PRODUCTS

ERPFlow.ai — multi-tenant SaaS ERP with EU Peppol BIS 3.0 e-invoicing, per-seat Stripe billing and 19 UI languages. API-first: 300+ endpoints behind one OpenAPI contract. Shipped in 2 months.

Deal.ee — AI-indexed Estonian business platform: ~368,000 companies from 19 government datasets, refreshed daily across ~2.2M URLs, built to be cited as a primary source by AI assistants.

Running our own products keeps us honest about what "production" actually means.

SELECTED CLIENT WORK

3DCraft.ee (manufacturing) — trilingual storefront with a WebGL hero that 3D-prints itself as you scroll. v1 in 2 months, v2 in 2 weeks.- EestiEpood.ee (e-commerce agency) — 84 prerendered pages in Estonian, Russian and English. Off Wix in 2 weeks, rebuilt in 1.- CarFog.eu (automotive) — trilingual, GEO-first storefront in 3 weeks.

STACK

Go and TypeScript, PostgreSQL, spec-driven development with OpenAPI, AI model orchestration, edge infrastructure. Next.js where SSR fits. We pick the right tool for each job — not the trendy one.

Senior execution, MVP to scale — without the hiring cycle.
