I architect software
that scales with the business.
Senior Full-Stack Engineer and Team Leader with 8+ years turning complex requirements into production platforms — from multi-tenant SaaS and enterprise ERPs to AI pipelines and hardware-connected systems.
Part of the Blue Developments team — trusted by companies across 10+ countries
Engineering that drives measurable outcomes.
I'm Kerollos Ashraf, a Senior Full-Stack Engineer leading a team of 7–10 engineers at Blue Developments — a Cairo software house building AI, web, mobile and embedded solutions since 2017 — and a Freelancer Plus engineer on Upwork.
I own products end-to-end: data modelling, APIs, real-time systems, front-end experience, cloud infrastructure and the team rituals that keep delivery predictable. My work spans enterprise ERP, multi-tenant SaaS, AI and voice pipelines, e-commerce automation and IoT.
What clients get is a senior engineer who thinks like a product owner: clear trade-offs, modular code that outlives the first release, and software that removes real operational friction.

Enterprise, ERP & POS
Inventory, finance, HR and point-of-sale workflows unified under strict access control.
Technical leadership
Leading 7–10 engineers: code review, estimation, mentoring and predictable releases.

Have a product to build? Let's talk.
Open to senior and lead roles, and to architecture or delivery engagements. I usually reply within a day.
