About CryptoPust
Backend engineering without the ceremony.
CryptoPust exists for technically difficult backend work: production failures, integrations, architecture problems, unreliable systems and narrowly scoped engineering problems that benefit from senior technical judgment.
CryptoPust is an engineering brand operated by FintechBear LLC.
01 / Engineering approach
Practical decisions for systems that need to hold up.
- Simple systems where possible.
- Explicit failure behavior where necessary.
- Production behavior matters more than architecture diagrams.
- Tests should prove important system behavior, not merely increase coverage numbers.
- External integrations should be treated as unreliable boundaries.
- AI-assisted engineering can accelerate implementation and analysis, but architecture, technical judgment and final review remain human-led.
02 / Engineering judgment
AI-assisted, human-reviewed
Modern engineering tools can accelerate implementation, investigation, testing, and review. I use them where they are useful.
They do not replace engineering judgment.
Architecture, failure modes, security boundaries, production risk, and final technical decisions remain human-reviewed.
03 / Technical focus
The systems and boundaries in scope.
- Backend systems
- Laravel / PHP
- .NET
- APIs and integrations
- Payments
- PostgreSQL / relational data
- Redis
- Queues and background processing
- Docker
- Production debugging
04 / Engagement model
Focused work for a defined technical problem.
CryptoPust is intended primarily for focused engineering engagements rather than long-term staff augmentation.
- Production RescueDiagnose and fix production-critical backend failures.
- Backend AuditReview architecture, authorization, data access, performance, security and production readiness.
- API & Integration WorkThird-party APIs, payments, webhooks and backend integrations.
- AI Code RescueTurn AI-assisted or vibe-coded applications into maintainable, testable systems.
- Feature SprintAdd a clearly scoped backend capability without long-term staff augmentation.
- Architecture ReviewIndependent technical review of architecture, failure modes and implementation decisions.
