Task

Tender specialists track dozens of lots in Excel + WhatsApp

In 2026 Kazakhstan's procurement market is 5+ trillion ₸/year via goszakup, Samruk-Qazyna and NADLoC. Thousands of lots, hundreds of players, dozens of tricky rules (tax regimes, VAT, guarantees, penalties).

The problem: suppliers track everything by hand. 200-column Excel sheets, margin calculated "on a napkin," statuses in a WhatsApp chat. Half the deals end up in the red - but they only find out at quarter-end.

Solution

A unified SaaS platform with an AI assistant

AI parses docs in 3 sec

Upload a PDF or DOCX - Claude extracts 20+ fields: amount, deadlines, customer, category. Used to take 15 minutes.

Profit calculator

All 6 KZ tax regimes, 12% VAT, logistics, guarantees - all factored in. You see the real margin before submitting a bid.

Multi-tenant with RLS

Each client's data is isolated at the Postgres level. Row Level Security + audit log on every change.

Stack

Chosen technologies

Every choice is justified. We took what works and passed on anything that adds complexity without payoff.

Next.js 16 + React 19

App Router, RSC, Turbopack. Great DX and performance out of the box.

TypeScript strict

In SaaS, typos are expensive. Strict types catch bugs before compile.

Supabase

Postgres + Auth + Realtime + RLS. No custom auth service.

Claude Haiku 4.5

Cheap, fast, great at parsing Russian and Kazakh documents.

Upstash Redis

Serverless rate-limit. Protects login from brute-force.

Sentry + Vercel Analytics

Out-of-the-box observability: errors, performance, Web Vitals.

Playwright E2E

Critical flows checked on every PR before merge.

Tailwind v4 + shadcn-style

A custom design system - not an off-the-shelf library.

Outcome

Production-ready in 4 months

A full SaaS with auth, multi-tenant, billing, AI, analytics, export and CI/CD. Ready for paying customers.
