About this gig

I will review your REST API or SaaS backend for practical application-security risks and give you a prioritized hardening roadmap.


I focus on:

authentication and authorization flows

tenant and data isolation, including sensitive-data exposure

input validation, error handling, and rate limiting

secrets and configuration boundaries

third-party integrations, logging, auditability, backups, and operational risk


You receive a concise findings report with severity and impact, recommended fixes, assumptions, and a staged remediation plan. If requested, I can implement a bounded set of agreed fixes in a follow-on scope.


This is an architecture and code-review servicenot a penetration test, compliance certification, legal opinion, or guarantee of security. I will not perform intrusive testing without explicit written authorization and a defined scope. Please share your stack, target endpoints, access constraints, and desired outcome before ordering.

I help businesses turn slow systems, unreliable integrations, disconnected data, and high-friction operations into maintainable software. I am a software and data architect specializing in APIs, backend services, databases, and AI-enabled workflows. My work targets a defined outcome: diagnose a bottleneck, design a credible architecture, implement an integration, or automate an internal workflow. I use AI-assisted engineering while keeping business rules, validation, tests, documentation, and maintainability central. I turn ambiguity into a clear scope and practical technical path.
