Backend Architecture Consulting & Technical Advisory

Good architecture is the simplest design that reliably meets your business needs. I help teams choose sound data models, API contracts, and service boundaries, then either hand over a clear plan or build it with you.

What I deliver

  • Architecture reviews and written design documents your team can act on
  • Data model and API contract design, with clear schema boundaries
  • Modular and event-driven designs for pricing, notification, and workflow engines
  • Scaling and reliability plans based on measured bottlenecks, not guesses
  • Code walkthroughs, documentation, and mentoring so your engineers own the result

When to hire me

  • You are about to build a new platform and want the key decisions reviewed first.
  • Your system works but is becoming slow, fragile, or hard to change.
  • You need a second senior opinion before committing to a vendor, framework, or rewrite.

Frequently asked questions

Can you work as an advisor without writing code?

Yes. Engagements can be advisory only (reviews, design documents, decision support) or hands-on, depending on what your team needs.

How do you approach technology choices?

I start from your business constraints, then choose battle-tested technology with the lowest operational cost that meets them.

Will my team be able to maintain what you design?

That is a design goal. I document decisions, run handoff walkthroughs, and mentor in-house engineers.
