About this gig

Is your SaaS slowing down under load? Are you worried about hidden bugs in your logistics or financial logic?

You don't need a rewriteyou need a diagnosis.

I am a Senior Software Architect specializing in High-Availability Systems. I don't just "fix bugs"; I perform forensic analysis on your codebase to identify the architectural flaws that will kill your business when you try to scale.

Most startups fail because of:

  • Concurrency Issues: Double-bookings or inventory mismatches due to missing atomic transactions.
  • Schema Bottlenecks: Poorly designed SQL/NoSQL relationships that freeze your app when you hit 1,000 users.
  • "Spaghetti" Microservices: Circular dependencies that make new features impossible to add.

What I Will Check:

  • Architecture: Microservices communication (gRPC/REST), rollback safety, and event-driven patterns.
  • Database: Entity Framework/Prisma usage, indexing strategies, and multi-tenant data isolation.
  • Security: OWASP vulnerabilities, IDOR checks, and proper JWT implementation.

My Tech Focus:

  • Backend: ASP.NET Core, Node.js, Express.js.
  • Data: PostgreSQL, MySQL, SQL Server, MongoDB.
  • Systems: Docker, Kubernetes, Azure/AWS.

I am a Senior Software Architect with 9+ years of experience engineering mission-critical systems for Logistics, SaaS, and Enterprise sectors. Unlike generalist developers, I specialize in the "hard parts" of software: Atomic Transactions, Multi-tenant Schema Design, and High-Concurrency Microservices. I bridge the gap between robust ASP.NET Core performance and Node.js agility. I have architected platforms handling complex consignment flows and AI-driven ERP automation. If you need code that is auditable, scalable, and rollback-safe, let's talk.
