Architecture & Scale
Blueprints for microservices, event-driven systems and payment systems that stay reliable under heavy load. Kafka, gRPC, AWS and Kubernetes, designed for high availability and smooth releases.
Available for consulting engagements
I build systems that scale, and teams that ship.
I'm Marc Al Mouallem, a principal software engineer and product leader. For 12+ years I've designed distributed systems used by hundreds of thousands of people. I help teams turn their product pipeline, from discovery to development, into a faster, partly automated process.

01 — About
Engineer by training, product leader by practice.
I design and deliver high-scale distributed systems: microservice architectures, event-driven platforms and payment systems. I've done this in fintech, hospitality and mental health.
Today I lead product and technical architecture at Sovra, a self-custodial DeFi finance platform with blockchain integrations. I run the weekly sprint planning and reviews, and I set the technical direction across mobile, backend and infrastructure.
The best results come when engineering and product work as one team. I help teams perform better by automating repetitive work in their product pipeline and coaching people to take on wider roles.

How I can help
Product Leadership
Hands-on product leadership: setting priorities, running weekly sprint planning and reviews, and keeping roadmap, architecture and delivery aligned so the team ships what matters.
Product Pipeline Automation
I map how ideas move from discovery to development and automate the steps that should be automated: research synthesis, specs, tickets, testing and release. Less busywork and fewer handoffs, so the team spends its time deciding and building.
Team Performance & Coaching
Code reviews, engineering best practices and one-to-one coaching that help engineers and PMs grow beyond their job titles. They learn to own more of the pipeline and to work alongside automation instead of competing with it.
03 — Approach
From discovery to development, automated where it counts.
-
Discover
Gather user signals, research and data, and let tooling sort and summarize it so the team can focus on understanding the problem.
-
Define
Turn insights into clear specs, acceptance criteria and backlog items using repeatable templates and automated handoffs.
-
Build
Clean architecture, CI/CD, infrastructure as code and automated quality checks, so the team can move fast without breaking things.
-
Grow
Coach each person to take on a wider role across the pipeline. A strong team improves the process long after an engagement ends.
