My Building Library

Hi, I'm Mialy 👋

AI Engineer & Solutions Architect (Apprentice)

I design secure, deterministic, and business-aware AI systems for real-world workflows. My background in institutional asset management brings a strong discipline around control, validation, governance, and risk — which I now apply to multi-agent systems, RAG pipelines, MCP-based integrations, and Web3 / Fintech products.

I build AI systems that do more than generate answers: they verify information, call tools safely, validate transactions, and operate with traceability in mind.

  • Specialization: Multi-Agent Systems, RAG, MCP, Secure AI Workflows, Web3 & Fintech
  • Current focus: AI architecture, trustworthy automation, agentic systems in production
  • Open to: 24-month apprenticeship / junior AI engineer roles / solutions architecture opportunities

Core stack

Python · TypeScript · React · AWS · Bedrock AgentCore · MCP · RAG · Agentic Workflows · FastAPI · Docker · Solana · GitHub Actions · SQL


What I build

I work at the intersection of AI engineering and operational reliability, with a strong interest in systems where data integrity, transaction validation, and human trust matter.

Selected projects

Project What it does Why it matters
novamart-multi-agent-support A multi-agent support system for an e-commerce workflow Shows orchestration, role separation, and specialist agent patterns
grounded-research-agent A grounded RAG agent that answers only from trusted sources Demonstrates source-grounded reasoning and refusal behavior
my-gecko-buyer A buyer agent that validates transactions before signing Focuses on trust, verification, and secure execution
support-chatbot-bedrock-agentcore AI support chatbot architecture with evaluation Brings product thinking and system-level AI design
agentcore-customer-support-agent End-to-end agent with tools, knowledge retrieval, and orchestration Illustrates practical integration patterns
one-step A local AI productivity assistant running in-browser Explores privacy-first, lightweight AI experiences

Background

After 10 years in institutional asset management, I moved into AI engineering because I wanted to build systems that combine operational rigor with intelligent automation.

That experience shaped my way of thinking:

  • validation over speed
  • traceability over opacity
  • governance over improvisation
  • trusted execution over hype

I bring that same financial discipline to AI architecture, especially in domains where correctness and accountability are critical.

Credentials

  • AWS AI & ML Scholars
  • Future AWS Agent Engineer Nanodegree
  • Strong interest in production-grade AI systems, multi-agent collaboration, and secure automation

Why I switched

I started coding to build a simple website for my own business. That quickly turned into a deeper interest in problem-solving, systems thinking, and software architecture.

Two things became clear:

  1. I enjoy being stuck on a technical problem until it becomes clear.
  2. I like building systems that do real work, not just demonstrations.

That was the turning point.


Learning in public

  • 📚 My Building Library — my technical notes, writing, and learning journey in English and French
  • ✍️ dev.to/mialy333 — articles and technical reflections
  • 🔭 Currently exploring: full-stack fundamentals, Docker/Kubernetes, and a multi-agent project built from first commit to production-ready architecture

Looking for

I am seeking a 24-month apprenticeship / junior AI engineer position where I can contribute to the deployment of trusted agent-based systems in production.

I’m especially interested in:

  • Multi-agent systems
  • RAG + knowledge-grounded AI
  • MCP and tool integration
  • AI for finance, operations, and digital services
  • Web3 / Fintech applications with strong validation and security requirements

Let’s connect

Open to feedback, collaboration, and conversations around AI architecture, agent systems, and trustworthy automation.

If one of these projects helped you, a ⭐ would mean a lot.
