Platform Architecture and Modernization
Evolve valuable systems through clearer capability boundaries, incremental migration, and architecture that preserves what already works.

Evolve the platform.Keep the business running.
I design adaptable platforms around stable business capabilities so companies can evolve, integrate, and modernize without costly rewrites.
Best suited for business-critical systems where migration, integration, reliability, or vendor risk has become an executive concern. Based in Fresno, working with teams nationwide.
- $158.6M+
- commerce revenue supported across 2.19M+ orders since September 2020
- 7 days → ~30 minutes
- API onboarding reduced through internal platform tooling
- ~$19K/month
- saved through measured infrastructure optimization
Platform Capabilities That Create Leverage
The work starts with a business capability that must survive change—not a framework preference or a feature list.
Commerce Platforms and Enterprise Integrations
Keep pricing, payments, loyalty, fulfillment, analytics, and finance capabilities resilient as vendors and channels change.

Independent technical judgment
Need a decision before committing to implementation?
Start with a focused architecture review, integration audit, or AI workflow assessment. Each produces evidence and a concrete next-step recommendation before a larger budget is committed.
Consulting fit
Best for companies carrying real platform risk.
This is a strong fit when architecture affects revenue, operations, migration risk, engineering leverage, or the ability to change vendors. It is not a fit for commodity brochure sites or technology selection without a defined business capability.
Discuss Your Platform ChallengeA platform must change without interrupting the business
Commerce, operational, or customer workflows need a safer migration or modernization path than a big-bang rewrite.
Vendors and integrations are defining the architecture
Shopify, NetSuite, payments, loyalty, fulfillment, analytics, or cloud constraints are leaking into core business decisions.
A lean team needs more engineering leverage
The team needs clearer boundaries, safer defaults, lower cognitive load, or principal-level support before the next hire or platform investment.
How I think
Architecture should make change less expensive.
These principles guide platform, integration, migration, and reliability decisions under real business and team constraints.
Read the design principles →Build around business capabilities
Keep durable business behavior separate from vendors and implementation details.
Optimize for change
Make the next likely migration, integration, or policy change less expensive.
Optimize for the next engineer
Make dependencies, ownership, and failure behavior easier to understand.
Prefer practical simplicity
Choose the least complex architecture the team can operate confidently.
Who you'll work with
Antonio Perez, Principal Platform Engineer
Antonio has more than a decade of experience owning commerce, API, integration, data, and cloud platforms. His work includes internal platform tooling that reduced API onboarding from seven days to approximately 30 minutes and architecture leadership across engineering, finance, analytics, fulfillment, and operations.

Designing a Commerce Platform Around Capabilities, Not Vendors
An anonymized architecture case study from commerce platform work that supported 2.19M+ orders and $158.6M+ in revenue since September 2020, showing how capability boundaries, explicit vendor adapters, and recoverable integrations preserved business flexibility.
- Capability-oriented boundaries for pricing, payments, loyalty, orders, fulfillment, analytics, and finance
- Stable business-facing APIs and orchestration contracts
- Vendor-specific adapters for commerce, payment, fulfillment, and enterprise systems
- Explicit source-of-truth, identifier, and lifecycle ownership

Bring the platform challenge.
Share the business capability that must change, the systems and vendors involved, and what cannot be interrupted. I will help clarify the architecture, migration path, and smallest responsible next step.
Discuss Your Platform ChallengeI’ll review the context and determine whether a focused engagement, larger implementation, or another option is the most responsible next step.
