About Me

Product Maker First.
Engineer Second.

I have never been satisfied with just writing code. My obsession is solving the problem.

Throughout my career, whether automating a warehouse in the US or architecting a fintech core, I have operated as a Product Maker first, Engineer second. I don't just build features; I build solutions that drive business outcomes.

The AI Manifesto

Why I build with AI

The Democratization of Logic

I consider Artificial Intelligence to be the most democratic technology since the birth of the Internet. It has collapsed the barrier between "Idea" and "Execution". It doesn't care about your pedigree; it cares about the clarity of your logic. But access to the tool doesn't guarantee the quality of the result. That requires engineering discipline.

Velocity & Obsolescence

AI is the highest-momentum value add in history. It is the fastest way to compete, but also the fastest way to become obsolete. In this new era, "Seniority" isn't measured in years of syntax memorized, but in the ability to orchestrate systems that solve real human problems.

Expertise vs. Enthusiasm

I am not an AI enthusiast; I am an AI Product Engineer. There is a massive difference between chatting with a model and integrating one into a mission-critical business workflow. I bring 10+ years of distributed systems experience to the chaotic world of LLMs. I don't use AI to learn how to code; I use it to ship robust products at speeds that were impossible a year ago.

The Journey

2021 — Present

Lead Software Architect & AI Product Engineer

Fintech & HealthTech Sectors

Moved beyond traditional engineering to lead the AI Product strategy. In the high-stakes Fintech sector, I didn't just maintain pipelines; I architected the trust infrastructure that enabled automated reconciliation for millions in transactions, treating data reliability as the core product feature.

Simultaneously, in HealthTech, I pioneered the transition from 'research AI' to 'production-grade AI'. I identified the friction in clinical workflows and deployed autonomous GenAI agents to handle sensitive patient data. The challenge wasn't just the LLM; it was building the safety rails, latency optimization, and user trust layers that turned a raw model into a usable medical product.

2019 — 2021

Independent Solutions Architect

Global Consultancy (US, Lebanon, LatAm)

Operated as a 'Fixer' for international organizations facing technical stagnation. I viewed Legacy Code not as tech debt, but as a business blocker. I led complex migrations (Monolith to Microservices) for a Lebanese data center, solving the critical problem of scalability and deployment velocity.

In the US market, I acted as a fractional product lead for healthcare startups, taking vague research requirements and fabricating MVP architectures from scratch. I bridged the gap between scientific study and deployable software, creating the early tooling that allowed researchers to analyze data at unprecedented speeds.

2017 — 2019

Senior Data Engineer

Insurance & HR Tech

Realized that for Insurance and HR, Data IS the Product. I shifted my focus to the backend engines that power decision-making. I solved the problem of fragmented, siloed information by building interoperable systems that could 'talk' to each other across borders.

This wasn't just about ETL pipelines; it was about designing a User Experience for Data. I engineered the migration strategies that allowed these companies to launch new digital services without losing a single record, effectively modernizing their entire business logic without disrupting operations.

2015 — 2017

Automation Engineer

US Construction & Logistics Niche

The roots of the 'Pragmatic Architect'. Working directly with business owners in the US construction sector, I saw the visceral pain of manual inventory management. I didn't just write scripts; I built end-to-end digital products that replaced paper trails.

I owned the entire lifecycle—from interviewing warehouse staff to deploying the server. This experience taught me that the best code is the one that deletes a problem. I transformed their operational chaos into streamlined digital workflows, proving early on that software is ultimately a tool for business leverage.
