Services
Choose the problem, define the boundary, fix it properly.
Senior backend engineering for broken, complex, and production-critical systems.
01 / Service packages
Each engagement is shaped around a specific technical problem and a clear boundary. The work can be implementation, review, or both.
Diagnose and repair a backend failure that is disrupting production or blocking delivery.
Errors that only appear under real traffic, unstable deployments, data access failures, or a backend path that cannot be trusted.
A bounded diagnosis, targeted code changes, tests for the repaired behavior, and clear handoff notes.
Not an open-ended rewrite, an on-call retainer, or a promise to solve unrelated system problems.
Review the backend as it exists and identify the risks that matter for reliability and delivery.
A team is inheriting an unfamiliar codebase, preparing a significant release, or trying to understand recurring backend risk.
A prioritized technical review covering architecture, authorization, data access, performance, security, and production readiness.
Not a certification, a compliance assessment, or a substitute for implementing every recommendation.
Build or repair the backend boundary between your system and an external API, payment provider, webhook, or service.
A provider is inconsistent, webhook handling is incomplete, a payment flow needs hardening, or an integration is slowing delivery.
A focused integration change with explicit failure behavior, validation, tests, and operational notes for the boundary.
Not a guarantee that a third-party provider will be reliable, stable, or within CryptoPust’s control.
Turn an AI-assisted or vibe-coded backend into a system that can be understood, tested, and maintained.
Generated code has reached production risk, behavior is unclear, tests are missing, or implementation needs senior review before it grows further.
A scoped review and targeted remediation that clarifies important paths, adds meaningful tests, and records remaining risks.
Not a blanket rewrite, an endorsement of every generated decision, or a replacement for product and architecture ownership.
Add one clearly scoped backend capability without creating a long-term outsourced development arrangement.
A feature has a defined boundary, the existing system is understood enough to change safely, and delivery is blocked on backend capacity.
An implemented feature with focused tests, integration notes, and a handoff that makes the next step clear.
Not a general backlog, indefinite feature development, or long-term staff augmentation.
Get an independent technical view of an architecture, its failure modes, and the decisions behind it.
A system is at an important design point, tradeoffs are unclear, or a team wants a second opinion before committing to a direction.
A concise review of the proposed shape, risks, alternatives, and implementation decisions worth making explicit.
Not architecture theater, a replacement for the owning team, or an attempt to design every detail without context.
02 / Engagement model
CryptoPust is intended for bounded engineering engagements, not generic agency work, long-term staff augmentation, or an outsourced development team.
Understand the system and define the actual problem.
Inspect code, architecture, and failure behavior.
Make targeted changes and verify the important behavior.
Deliver code, findings, and clear technical notes.
03 / Engagement boundary
CryptoPust is designed for focused engineering problems with a defined outcome.
If what you need is another developer embedded in your team indefinitely, this is probably not the right engagement model.
Start with the system and the problem. We can define a focused technical review from there.
