Executive Summary

I’m a technology architect and innovation strategist with hands-on expertise in full-stack development, cloud architecture, and agentic AI systems. I’ve designed, built, and scaled production platforms spanning social, education, e-commerce, and business intelligence domains.

My focus is building reliable, scalable, and economically sustainable systems — especially for emerging markets and real-world constraints.

What I Build

Cloud & Infrastructure

AWS, serverless systems, secure APIs, caching, CI/CD, scaling.

Full-Stack Architecture

PHP, JS, Node.js, SQL — APIs, auth, payments, performance.

AI & Intelligent Systems

Agentic AI, generative & predictive workflows, automation.

Mobile & Platforms

PWA systems, API-driven mobile backends, offline-first UX.

Product & Strategy

Product architecture, growth strategy, mentoring & leadership.

Selected Systems

Production platforms. Real users. Live infrastructure.

Tawkwell

Scalable social platform with cloud-native architecture.

Lazy-Student

AI-powered education platform with automation & payments.

Phantasy-Mart

Multi-vendor marketplace with logistics and inventory systems.

CloudAudit

Cloud accounting & inventory platform for SMEs.

On-Demand Errand & Logistics System

Operational platform for last-mile errands, task dispatch, rider coordination, pricing logic, and real-time tracking.

Thinking & Writings

Notes on systems, architecture, scaling, and building products that last.

Why Most Startups Collapse at Scale

Scaling failures are rarely about traffic. They’re about poor boundaries, state mismanagement, and cost-blind architecture.

Engineering for Longevity, Not Just Speed

Shipping fast matters — but systems designed without decay in mind become liabilities within 12–24 months.

When to Use Rust (and When Not To)

Rust is powerful, but misapplied Rust is worse than a well-designed higher-level system.

Start a Serious Conversation

If you’re building a real product or system and need a technical partner who understands architecture and execution, this is the right place.

I typically respond within 24–48 hours. Serious inquiries only.
