Front-end systems
Next.js interfaces, motion systems, and responsive patterns built for speed and clarity.
Our stack
Technologies organized by layers, not buzzwords.
FixProbs chooses tools for fit, maintainability, and delivery speed. This page shows how the stack is arranged so teams can move from product intent to reliable systems.
Product engineeringPostgreSQLCloud infrastructureAI workflows
Application services
API layers, background jobs, integrations, and workflows that keep the product moving.
Data foundations
PostgreSQL, analytics, event tracking, and clean persistence structures for reliable growth.
Infrastructure and security
Cloud deployment, monitoring, and guardrails that make scaling feel manageable.
Stack overview
A technical landscape built to stay understandable as it grows.
Rather than listing tools in isolation, the stack is grouped around the way a modern product actually ships.

Engineering principles
Every tool choice should reduce friction.
The right stack is one your team can actually operate, understand, and improve over time.
Fit to purpose
Choose the lightest stack that solves the problem without overcomplicating the system.
Fast iteration
Build for quick feedback loops so product decisions can be tested, measured, and refined.
Maintainability
Prefer readable architecture, reusable components, and predictable deployment patterns.
Operational visibility
Treat logging, alerts, and data flow as part of the product rather than extras.
