Built the way it should be built

I build enterprise-grade, AI-native SaaS platforms with clean architecture, secure by default, event-driven, and extensible — from an empty repository to production.

A multi-tenant SaaS platform & module marketplace

I architected it end to end and led the team that built it — the same people I have worked alongside for a decade, most of whom co-founded Clever Initiative with me. A production-grade, multi-tenant SaaS platform with an installable-module marketplace: .NET on the backend, a modern Angular frontend, and a strict engineering charter. Here is what it does and how it holds together.

Multi-tenancy with complete isolation

Database-per-tenant with AES-256-encrypted per-tenant connection strings, a five-step tenant-resolution chain, and zero shared tables.

Architecture

Clean Architecture · DDD · CQRS

Layer boundaries enforced at the project-reference level, a MediatR command/query pipeline with logging, validation, caching, and transactions, and the Result pattern for expected failures.

0 shared tables between tenants.

i18n & white-label

Multilingual from day one, with per-tenant branding and custom domains so the platform disappears behind each client’s brand.

Security by default

Short-lived JWTs with rotating refresh tokens, BCrypt at cost-factor 12, O(1) permission checks from claims, defense-in-depth authorization, TOTP 2FA, OAuth/OIDC social login with PKCE, security headers, rate limiting, and GDPR-aware audit logging.

Real-time

SignalR hubs — JWT-authenticated, per-tenant groups — powering notifications, chat, and token-by-token AI streaming.

DevOps & production

Docker and GitHub Actions CI/CD, self-hosted on hardened Ubuntu (Nginx TLS reverse proxy, PostgreSQL, Redis, RabbitMQ, structured logging, UFW + fail2ban + SSH hardening) and on Azure with managed services and Kubernetes — health checks, correlation IDs, slow-query logging, and full observability.

Marketplace

Installable-module marketplace

Signed, versioned modules loaded at runtime into isolated AssemblyLoadContexts with no redeployment — per-module databases and migrations, dynamic navigation and permissions, and published cross-module contracts with graceful NoOp fallbacks.

Read the case study

Event-driven integration

A transactional outbox with RabbitMQ via MassTransit — at-least-once delivery, idempotent consumers, and a clean split between in-process domain events and cross-process integration events.

Architecture

Inside the core

Two views of the same platform: the layers the code may depend on, and the path every state change travels.

Clean Architecture

Dependencies point inward — the domain depends on nothing.

Event-driven flow

  1. Command / Query
  2. MediatR pipeline
  3. Transactional outbox
  4. Message bus
  5. Idempotent consumer
Every state change is captured once and delivered reliably.
How I work

The intelligent way of working

I lead and build with AI agents and AI engineering as a tech lead — orchestrating, reviewing, and shipping at a speed and quality the old, manual way can’t match. It’s not a gimmick; it’s how I hold a higher bar across more surface area.

AI-agentic by method

I orchestrate AI agents across the engineering loop — design, implementation, review, and tests — and stay the architect who owns every decision.

Source-verified, always

Before I commit to a library, an API, or a pattern, I verify it against the authoritative source. I don’t ship what was true a few years ago.

A hard quality bar

Zero build warnings, the full test suite green after every change, and migrations shipped with the change that needs them. No shortcuts, no “fix it later.”

A few systems I’ve taken from problem to production.

FeaturedPlatform · architecture & team leadership · 2024 – Present

Multi-tenant SaaS platform & module marketplace

Architected a production-grade, multi-tenant platform with an installable-module marketplace from an empty repository, and led the team that built it — clean architecture, an event-driven core, and security by default.

Challenge
One platform that many businesses can run on: every tenant fully isolated, every product assembled from composable modules — without forking the codebase.
Outcome
In production at Clever Initiative. Our first enterprise client, Fininly B.V., runs its investment platform on it and resells it to its own clients under its own brand. After a live demo of the MVP-stage platform in Toronto in May 2025, CIG Holding wrote that “80% of our platform needs were already implemented.”
