Kareem Hamed Ibrahim Backend Software Engineer | Go & Laravel

I build backend systems that turn bottlenecks into momentum. I started my journey in Laravel, where real-world commerce and logistics taught me scale. Today, I design Go services that keep data fast, reliable, and observable under pressure.

Working principle Every system tells a story. I make sure the ending is faster, safer, and ready for the next chapter.

Story

From Laravel foundations to Go systems

Building in chapters, not sprints

My work is a continuous narrative of building for real users, shipping under deadlines, and returning to improve what matters most: speed, reliability, and clarity.

Chapter 1 — Foundations in product engineering

I learned to build features with clarity: converting Figma into usable interfaces, wiring APIs for mobile apps, and keeping production stable.

Chapter 2 — Performance as a habit

Optimization became a routine: caching, eager loading, and database tuning turned heavy workloads into responsive experiences.

Chapter 3 — Distributed systems with Go

Go opened the door to concurrency, gRPC, and observability. I now design services that scale gracefully and fail loudly, not silently.

Experience, told as progress

Each role shaped a new layer of how I think about systems and impact.

Mada Software — Software Engineer (03/2024 – Present · Cairo, Egypt)

I translated complex business requirements into scalable APIs and dashboards. I built a Go microservice to replace a slow analytics engine, cutting latency from 25s to 500ms on 10M+ records, and introduced CI/CD that reduced deployment errors by 80%.

PikyHost LTD — Fullstack Developer (06/2023 – 03/2025 · Remote)

I helped build a multi-vendor platform from the ground up, shaping the user journey from discovery to checkout and making the business logic resilient across services.

Chaara App — Backend Developer (06/2023 – 07/2024 · Remote)

I engineered secure workflows and auction modules for a live platform in Spain, improving performance by 70% through proactive optimization and focused architecture decisions.

Projects that tell the full story

From microservices to marketplaces, each project is a chapter focused on scale, reliability, and clarity.

High-Performance Analytics Sidecar

A Go service that offloaded heavy analytics from a Laravel monolith, bringing response times down to 500ms with Redis cache warming and worker pools.

E-Commerce Microservices Platform

Four gRPC services with OpenTelemetry tracing that exposed bottlenecks and delivered resilient, observable commerce APIs.

Point of Sale (POS) API

A hexagonal architecture backend with rate limiting, Redis-backed session control, and concurrency-first logging.

Distributed Ride-Sharing Backend

Event-driven services with RabbitMQ and WebSockets to keep drivers and riders synchronized in real time.

Mada Store (Multi-Vendor)

Commission and payout workflows, auction modules, and multilingual support for a production e-commerce platform.

Knowledge University System

Role-based dashboards and secure data workflows supporting academic, financial, and user management.

25 seconds is an eternity in Software Engineering

How I reduced a legacy dashboard's data fetch latency from 25 seconds to 500ms using Go microservices and intelligent caching.

Learning Microservices by Building an E-Commerce Platform in Go

A journey through distributed systems design, from API Gateway to microservices orchestration, all built from scratch in Go.

The AI Agent That Almost Cost Me a Security Breach

A cautionary tale about delegating critical code to AI without understanding it. When a missing return statement becomes a data leak.

If It Acts Like a Duck, Then It's a Duck: Go's Implicit Interfaces

Understanding Go's structural typing, the hidden pitfalls, and the one-line trick that saves you from silent implementation bugs.

Skills

The toolkit behind the story

A blend of backend depth, system design, and delivery discipline.

Go, PHP (Laravel), SQL

I choose the language that serves the mission: Go for concurrency, Laravel for fast product iteration, and SQL for data integrity.

Distributed systems & architecture

Microservices, gRPC/Protobuf, event-driven messaging, and hexagonal architecture for clean boundaries and scale.

Performance & observability

OpenTelemetry, Jaeger, caching, indexing, and profiling to keep systems predictable and diagnosable.

Data & infrastructure

PostgreSQL, MySQL, MongoDB, Redis, Docker, Nginx, and Linux administration for production-grade stability.

Engineering discipline

SOLID principles, unit testing, clean architecture, and CI/CD pipelines that keep teams shipping safely.

Collaboration & delivery

Cross-functional work with design and product to turn Figma ideas into production features.

Education

Grounded in computer science

The academic foundation gave me the vocabulary to reason about systems and the discipline to keep learning.

B.Sc. in Computer Science — Suez University

GPA 3.41/4.0 (B+ with Honors). Graduation project: Deep Fake Detection Model (A+).

Focus areas

Algorithms, data structures, OOP, UML, and software design principles.
