OpsQuanta

Project Overview

FinCo GmbH, an 18-person payments startup in Frankfurt, was drowning in ops overhead, over 200 support tickets/month, half of them simple “What’s the status?” queries that ate up 10 hours/week of their 5-person ops team. To fix this, we built OpsQuanta, an internal workflow tool, meant to automate status updates and streamline ticket handling.

With an upcoming audit and zero internal engineering capacity, they engaged us to translate their finalized Figma designs into a production-ready, fully owned internal tool, delivered in 90 days to meet their validation deadline.

The Challenge

The client faced three key issues:

• No internal engineering team to drive development and delivery.
• Complex role-based access logic that no-code platforms couldn’t support.
• A fixed delivery deadline tied to an internal roadmap and operational audit.

Off-the-shelf solutions were ruled out due to strict design fidelity requirements and limited support for multi-role dashboards. Midway through, onboarding logic was redefined—without a modular architecture, this change would have risked timeline slippage.

Our Approach

We led the full-stack implementation with a focus on agility, modularity, and maintainability.

Frontend

• Built a modular React 18 + TypeScript component library using Next.js and TailwindCSS for pixel-accurate, responsive UIs.

Backend

• Implemented Node 18 + Express API with PostgreSQL and row-level security; scoped middleware enforced admin, staff and client roles.

Security & QA

• Role-based access control, audit-trail middleware logging user, timestamp and IP hash, plus CI/CD pipelines running unit, integration and E2E tests on every merge.

Deployment

• Deployed on Vercel with GitHub Actions CI/CD; staging and production environments managed via version-controlled env vars—no client DevOps overhead.

Handoff

• Delivered full technical docs, API endpoint specs and component index, plus a recorded code walkthrough for seamless onboarding of their in-house developer.

Change Management

• Modular structure allowed isolated updates when onboarding logic changed—no regressions and zero timeline impact.

The Solution

• Pixel-accurate frontend built with Next.js and TailwindCSS
• Backend with Node.js and PostgreSQL, supporting scoped role-based access
• Modular, responsive React 18 + TypeScript component system
• Separate dashboards for admin, staff and client roles
• Secure, scalable API with token-based authentication
• CI/CD via Vercel and GitHub Actions
• Versioned staging and production environments
• Developer documentation and recorded walkthrough for rapid ramp-up

Business and Technical Outcomes

• Identified and resolved 2 critical launch issues within 24 hours post-launch, with minimal ops impact
• Zero critical issues reported in the first 30 days
• Faced unexpected caching conflicts in staging vs production—patched and re-deployed in under 6 hours
• 90% drop in status-check tickets, saving 10+ hours/week of manual work
• 98% cross-device compatibility across 20+ screen sizes
• 100% code ownership and modularity—client can scale and extend independently
• Pre-configured CI/CD pipelines enabling rapid iteration with minimal downtime

The Impact

Launched on schedule, the tool immediately streamlined daily workflows and eliminated manual handoffs. Their in-house developer onboarded in under 24 hours, thanks to clear documentation and a well-structured codebase.

With full code ownership and a modular design, FinCo GmbH can now adapt, scale or extend the platform without vendor lock-in or additional support.
