Here are feedbacks from my previous clients:
"Direct Quote from FAANG measurement manager who worked with Hamza for over 1.5 years:
"I had the privilege of working alongside Hamza in his role as a Senior Cloud & Back End Engineer. Hamza's comprehensive understanding of computer science, architectural and design patterns, and cloud technologies played a pivotal role in the success of our initiatives. His acumen in developing and implementing robust, scalable solutions was apparent in our marketing campaign planner. His expertise in Python, Javascript, and his adept use of databases like PostgreSQL and Firebase made him an integral part of our team.
Hamza's proficiency in leveraging Google Cloud Platform was instrumental in enhancing our project's performance. He skillfully increased our systems' efficiency by utilising GCP MemoryStore, and his efficient handling of background tasks using Cloud Run and Cloud Scheduler was truly commendable. His pragmatic approach to backend development and extensive knowledge of API design and web security significantly contributed to the stability and performance of our software.
Hamza's ability to balance his advanced technical skills with excellent communication abilities set him apart. His commitment to the team, made him a reliable team player. His dedication extended to meticulously reviewing the code developed by others, and his feedback invariably improved our productivity and work quality. I confidently recommend Hamza for any role requiring expertise in cloud and backend engineering. His potent combination of cloud and backend skills, coupled with his professional dedication, will undeniably be an asset to any team fortunate enough to have him""

I’m a Senior Full-Stack & AI Engineer specializing in building end-to-end AI-powered products, automation systems, and scalable SaaS platforms.
Over the past 5+ years, I’ve moved beyond traditional development into designing complete systems, where AI, APIs, automation workflows, and business logic work together reliably in production.
AI Agents & LLM Systems. Build production-ready AI agents using OpenAI / Claude with
- structured outputs (JSON workflows)
- memory (RAG, vector DBs)
- multi-step reasoning & tool usage
- human-in-the-loop validation
Automation & Workflow Systems (n8n / Make). Design end-to-end automation pipelines:
- lead intake → enrichment → CRM sync → follow-ups
- scheduled agents running 24/7
- failure handling, retries, and monitoring built-in
Full-Stack SaaS Development. Deliver complete applications using:
- Next.js / Tailwind / Svelte / Angular / TypeScript (frontend)
- Django / FastAPI / Node / Nest / Express (backend APIs & services)
- PostgreSQL / Supabase (data layer)
API Integrations & Data Pipelines
- Stripe billing & subscriptions
- CRM systems (GoHighLevel, HubSpot, etc.)
- Marketing APIs (Google Ads, Meta)
- Custom ingestion pipelines (real-time + batch)
I focus on systems.
1. I design complete workflows, not isolated features
2. I handle edge cases, failures, and reliability from day one
3. I translate business goals → technical architecture → working product
4. I can take a rough idea or spec and ship independently
If you’re looking for someone who can connect AI, automation, and real business systems into a working product, not just prototype, I’m exactly that partner.
