Do any of these sound familiar?

"I have a SaaS idea but no team to build it."

I'll ship your MVP in 6-8 weeks with a production-ready stack. You validate the market, I handle the engineering.

"Our internal processes run on spreadsheets."

I build custom ERPs that automate your workflows. Used by RichOil, Aqrar Portal, and other production systems.

"Our website looks outdated and converts poorly."

I deliver fast, modern marketing sites in 2 weeks. Vue 3, 90+ Lighthouse score, SEO-ready.

Reclaimer

Dispute & collections dashboard

Reclaimer

The challenge:

Small companies serving corporate clients track large volumes of late payments by hand. Drafting legal dispute letters and follow-up reminders is slow and scattered across email threads and spreadsheets.

B2B SaaS · Fintech-adjacent · 2025–2026

AI-assisted SaaS for US & UK small B2B teams — professional dispute letters and automated reminders for overdue invoice & contract payments

What I built:

• Nuxt 4 + Vue 3 marketing site (prerendered) and /app dispute management panel
• Invoice & contract PDF upload with text extraction; Gemini Vision fallback for scanned PDFs
• AI analysis of breached terms, late fees, risk/basis, and dispute letter generation (Gemini & configurable providers)
• Letter editing in TipTap; outbound via SMTP, Gmail OAuth, or Resend; cron-driven 7- and 14-day reminder flows
• JWT sessions, Google OAuth, email verification & password reset; PostgreSQL with migration scripts; Docker-ready deploy
• Dashboard KPIs, ApexCharts, dispute list & timeline, security and account provisioning flows

The result:

Built to compress weeks-long payment follow-up into minutes, with recovered amounts tracked on the dashboard. Public production metrics are not published in the codebase.

About me

I'm Umud — a freelance full stack developer based in Azerbaijan (GMT+4) with 3.5+ years shipping production systems as a Vue Nuxt freelancer and FastAPI developer.

I specialize in SaaS MVP development and custom ERP development for B2B teams — from dashboards and APIs to deployment on Docker and CapRover.

When I'm not coding client work, I build my own SaaS products and write about engineering on LinkedIn.

50% upfront, 50% on delivery. For larger projects, we use milestone-based payments. I accept Wise, Stripe, and bank transfers (USD/EUR).
