Antonio Perez · Principal Platform Engineer
I design adaptable commerce, integration, API, and operational platforms around stable business capabilities—so companies can migrate, 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.
commerce revenue supported across 2.19M+ orders since September 2020
API onboarding reduced through internal platform tooling
saved through measured infrastructure optimization
The work starts with a business capability that must survive change—not a framework preference or a feature list.
Evolve valuable systems through clearer capability boundaries, incremental migration, and architecture that preserves what already works.
Platform Architecture and Modernization →Keep pricing, payments, loyalty, fulfillment, analytics, and finance capabilities resilient as vendors and channels change.
Commerce Platforms and Enterprise Integrations →Get principal-level judgment on platform risk, distributed systems, migration strategy, technical due diligence, and the next responsible investment.
Architecture Review and Fractional Support →Consulting fit
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 ProblemCommerce, operational, or customer workflows need a safer migration or modernization path than a big-bang rewrite.
Shopify, NetSuite, payments, loyalty, fulfillment, analytics, or cloud constraints are leaking into core business decisions.
The team needs clearer boundaries, safer defaults, lower cognitive load, or principal-level support before the next hire or platform investment.
How I think
These principles guide platform, integration, migration, and reliability decisions under real business and team constraints.
Read the design principles →Keep durable business behavior separate from vendors and implementation details.
Make the next likely migration, integration, or policy change less expensive.
Make dependencies, ownership, and failure behavior easier to understand.
Choose the least complex architecture the team can operate confidently.
Who you'll work with
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.
Replacing a production data store without turning the migration into an application rewrite
An anonymized architecture case study on using repository adapters, idempotent data movement, reconciliation, and a reversible cutover to migrate a business-critical Node.js platform from MongoDB to PostgreSQL while the application remained available.
Engineering judgment for systems that need to survive changing vendors, technologies, requirements, and engineers.
How web-based GIS, shapefile tools, and operational dashboards can support California water agencies, agriculture teams, and local land management workflows.
How Candid Moments uses direct S3 uploads, durable PgBoss jobs, Rekognition, persisted state, and host controls to process event media safely.
A practical architecture for AI agents that can read business data, draft actions, and stay inside controlled permission boundaries.
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.
