Integration Maestro

Integration & Systems Architect · ERP · eCommerce · High-Load
The architect between the business and the engineering team.
12+ YEARS · ADOBE COMMERCE · SHOPWARE 6 · SHOPIFY · ERP-FIRST ARCHITECTURES
How I see my role
I stand between the business and the engineering team.
- Take a business problem → scope what belongs in the MVP and what comes later → identify the risks before development starts → translate it into a plan the team can execute.
- 12+ years across ERP, OMS, and logistics integrations, on multi-brand, multi-market platforms; led delivery orgs of up to 18 engineers.
- Present options and recommendations to Director- and VP-level stakeholders in terms of cost, risk, and conversion impact, not technical language.
- Use AI in the work itself: not just code generation, but analysis, structuring proposals, and reducing overhead on the team.
"I never bring a problem without options."
What I do
Building the systems that connect commerce to everything behind it.
01
ERP ↔ eCommerce Integrations
Real-time, cache-aware systems
- Catalog, inventory, orders, invoices, shipments
- Delta sync with reconciliation
- Reusable, config-driven contracts
02
Architecture Governance & Delivery
Discovery, standards, ownership
- Technical discovery, scope & MVP
- Standards, reviews & decision records
- Tech-debt reduction & roadmaps
03
Event-Driven & High-Load Systems
Performance under pressure
- RabbitMQ pipelines & batch workers
- Redis, Elasticsearch, Fastly CDN
- Observability & reliability
How I work
Discovery first. Options, not problems.
- Analyze the scale first. Understand the real size of the task before decomposing it into tickets, not the other way around.
- Name the MVP explicitly. What ships now, what comes after launch, stated out loud.
- Surface risk before development. Every plan comes with a rollback or contingency.
- Communicate up in business terms. Cost, risk, timeline, conversion impact; no jargon without a plain-language bridge.
I question the inputs. "No budget limit" gets a follow-up, not a nod.
How I lead architecture
Governing architecture across many teams and many projects.
- Standards & reviews. Reference architectures, architecture reviews, and decision records that keep many parallel projects on one coherent architecture.
- Tech debt as measured work. I treat debt reduction as a program with outcomes: reliability, delivery speed, and total cost, not a side task.
- Across distributed teams. Aligned backend, frontend, QA, and PM across markets and offshore delivery partners.
- Mentoring. I coach engineers and leads into architects through design-doc pairing and review forums.
Influence without authority: the diagram, the trade-off, and the cost case do the convincing.
Case 01 · ERP-first platform (current)
One integration platform, 75% faster client delivery.
Context
A commercial B2B integration platform connecting Magento 2, Shopware 6, and Shopify with ERP systems across manufacturing, wholesale, and distribution.
What I did
Standardized a configuration-driven architecture with reusable integration contracts, and led discovery, roadmaps, and risk identification on every engagement.
Key design
Delta synchronization that moved catalog sync from overnight batch to near-real-time, with reconciliation.
Result
3 months → 3 weeksclient integration delivery time (75% faster)
1-2s → under 100msGraphQL response (Redis, RabbitMQ, ERP adapters)
Business meaning: faster onboarding, far cheaper delivery, and real-time data in place of overnight lag.
Case 02 · Peak-season risk
Black Friday, without a single incident.
Context
A multi-brand Adobe Commerce platform supporting 15 retail brands. Peak-season feed processing was too slow to keep prices and stock current.
What I did
Redesigned the asynchronous feed processing architecture, and brought the business two options with the conversion risk attached to each, not a task to "rewrite the feeds."
How I framed it
Cost of each option against the conversion risk if stale data hit peak traffic, plus the timeline and the fallback.
Result
4h+ → 26 minBlack Friday / Cyber Monday feed processing
0 incidentsno operational impact through peak
Business meaning: peak-season revenue protected; leadership walked into Black Friday calm.
Case 03 · Zero-downtime upgrade
15 sites upgraded, a non-event for the business.
Context
A Magento 2.4.3 to 2.4.5 upgrade across roughly 15 live sites, on the same multi-brand platform.
What I did
Removed the fear through risk management: a phased rollout, per-site rollback, and regular updates to stakeholders in plain business language.
My role
Led the delivery org of 18 engineers across frontend, QA, PM, and Scrum, and owned the executive communication that kept leadership confident.
Result
15 sites · 0 downtimephased, controlled rollout
18 engineersdelivery org I led across markets
Business meaning: a migration everyone feared became something no one had to worry about.
Case 04 · Scale through automation
10× parcel volume, absorbed by automation.
Context
A logistics and supply-chain automation platform that needed to scale fulfillment without scaling cost.
What I did
Built warehouse and fulfillment automation, integrated carrier APIs, and optimized routing across end-to-end order processing.
First move
Mapped where cost and manual load actually lived, then automated the parts that would otherwise need more people.
Result
10× volume · 108,000+parcel throughput · parcels delivered
50% lowerdelivery cost, via routing & carrier integration
Business meaning: growth absorbed through automation instead of headcount.
The Integration Maestro Rules
Named principles: the "why" and the "what if," not just the "how."
RULE 01
The Distributed Reality Rule
Every integration is a distributed system, whether you like it or not.
RULE 02
The Latency Compounding Law
Integration latency compounds. It never simply adds.
RULE 03
The Idempotency Mandate
If it can retry, it must be idempotent.
I design for the edge cases and the systems under load. That's where integrations actually break.
Technical depth, AI & credentials
Architecture decisions: yes. And the credentials to back it.
- I go deep on architecture, integration patterns, data flows, and technical constraints, and make concrete decisions with the team.
- Recent focus has been architecture and stakeholder management, close to the engineering team. Day-one PHP would take a short 2-3 week warm-up; guiding the team's technical decisions is what I do now.
- AI is part of my workflow: analysis, structuring proposals, and reducing team overhead, not just code generation.

Why I fit a Systems Architecture role
The bridge between business objectives and technical delivery.
- Delivery under pressure: peak season, migrations, tight timelines, measured in outcomes and reliability, not tickets.
- Multi-brand at scale: ran a 15-brand Adobe Commerce platform; I balance a shared platform against each brand's need to move fast.
- Lower cost and risk: I modernize to cut tech debt and total cost of ownership, not for elegance.
- Communicates upward in cost, risk, and ROI, then translates it into a plan the team executes.
