I Build Scalable Systems, AI Platforms, and Developer Tools

Solutions Architect focused on MongoDB, AI pipelines, and cloud-native systems across AWS, GCP, and Azure — from freemium products to distributed trading and LLM routing platforms.

I design production architectures that stay operable under real load: clear boundaries, measurable reliability, and tooling teams can actually ship with.

Dario Maddaluno

Solutions Architect · Founder

I build and operate production AI platforms and cloud-native systems end to end — freemium products with Stripe entitlements, multi-strategy trading stacks, and LLM routers with live budgets. The through-line is reliable architecture, fast iteration, and systems that stay understandable as they scale.

Live Products

Production systems in active use — each with real billing, data, or routing responsibilities, not demos.

Promptalo

LIVE

Ship prompts as a product: Manifest V3 Chrome extension, Stripe freemium billing, and MongoDB-backed entitlements with rate limits.

Systems & Architecture Work

Alongside live products, these platforms are in active engineering — focused on automation depth, AI explainability, and multi-service operations.

Pro League Project

Coming SoonAutomation System

End-to-end sports betting automation: ingest market data, evaluate opportunities against budget rules, and execute on a schedule with operator-visible controls.

DCRE

Coming SoonAI Video System

Multi-model video pipeline that classifies frames across 22 safety categories with explainability, targeting ~0.5–1s per frame for multi-user workloads.

Posting Manager Platform

Coming SoonMulti-Service Platform

Social publishing architecture spanning scheduling, media management, and analytics — designed for multi-user scale rather than a single-account tool.

How I Build Systems

A practical engineering mindset for products that have to run in production — not just look impressive in a pitch deck.

  • Systems over features

    I design durable boundaries and data flows first, then ship features inside that architecture.

  • Scale and real-time by default

    Workloads that matter usually need shared caches, queues, or schedulers — not one-off scripts.

  • Complexity only when earned

    No RAG, microservices, or exotic stacks unless the problem clearly pays for them.

  • Velocity without chaos

    Clear modules, typed contracts, and operable dashboards so teams can move fast safely.

  • AI as an accelerator

    I use AI to speed prototyping and boilerplate — architecture and validation stay engineered.

AI-Assisted Development Workflow

AI is part of how I ship — tightly scoped to productivity, never a substitute for system design.

  • Accelerate the boring path

    AI speeds scaffolding, refactors, and exploratory prototypes so more time goes to hard design choices.

  • Keep architecture human-owned

    System boundaries, data models, and failure modes are designed and reviewed manually before they ship.

  • Assist, don’t decide

    Models help with options and drafts — production decisions stay with engineering judgment and tests.

  • Optimize for operable software

    Correctness, observability, and maintainability beat clever one-offs every time.
