I am Emad Khan

I help CTOs and engineering leaders turn slow, fragile systems into high-performance platforms built for national-scale traffic. From crushing an 82-second query to under 1 second to contributing to Hayya — Qatar's national entry-permit and e-visa platform that processed 2.4M+ applications during FIFA World Cup 2022 — I deliver results you can measure in performance, scale, and uptime.

What I Do

Stop Hiring Developers.
Hire an Architect.

Most engineers write code. I design systems that handle national-scale traffic spikes, integrate with regulated third-party identity systems, and stay observable at scale. Available on retainer, project-based, or hourly.

⚙

Enterprise Architecture & System Design

I take your monolith and turn it into a distributed, fault-tolerant system using .NET Core 8, microservices, CQRS, and event-driven architecture — without downtime.

Monolith → microservices with zero downtime

Technical Leadership & Team Scaling

I don't just manage teams — I build engineering cultures. Sprint velocity up, P0 incidents down, and developers who actually want to stay. Proven with 15+ person cross-functional squads.

Performance Engineering & Query Mastery

Your users are leaving because your app is slow. I find the bottleneck — whether it's N+1 queries, missing indexes, or bad EF Core patterns — and fix it permanently.

Cloud Architecture & DevOps

Azure, AWS, Docker, Kubernetes, CI/CD — I design infrastructure that auto-scales, self-heals, and stays observable end-to-end with telemetry your on-call team can actually use.

How I Work

From Discovery to Delivery

A structured approach refined over 12+ years and 30+ enterprise projects.

Discovery

Free 30-min call to understand your challenges, architecture, and goals. I ask the questions your team hasn't thought of yet.

Architecture

Technical proposal with system design, timeline, and clear deliverables. No surprises. You know exactly what you're getting.

Build & Ship

Iterative development with weekly demos. I integrate with your team's tools, sprints, and workflows — not the other way around.

Support

Post-delivery optimization, knowledge transfer, and documentation. Your team owns it fully. No vendor lock-in.

Why Me

Most Architects Design Systems.
I Design Outcomes.

I architect solutions that scale to national infrastructure level — Hayya processed 2.4M+ entry-permit applications during FIFA World Cup 2022 (peak: 50,000 in a single day) and now serves 2.7M+ active users as Qatar's e-visa gateway. I cut a critical SQL query from 82.2 seconds to under 1 second on a 65,000-row dataset. The receipts are public.

From contributing to Hayya (Qatar's national entry-permit and e-visa platform) to shipping Efare — a full-stack ride-hailing platform with native iOS and Android apps for drivers and riders — I bring deep technical skill and business acumen that turns engineering investments into competitive advantages. I also build and ship my own developer tools — because real engineers solve their own problems too.

Common Questions

Frequently Asked Questions

I offer three models: Retainer (ongoing monthly commitment, best for long-term architecture work), Project-based (fixed scope and price), and Hourly consulting (for code reviews, audits, and advisory). Every engagement starts with a free 30-minute discovery call.
I'm based in Pakistan (GMT+5) and have worked with teams across the US, UK, UAE, and Qatar. I'm flexible with overlap hours and async communication — most of my enterprise clients are in US/EU timezones.
Currently available for new engagements alongside my Al Jazeera work. I can commit 20-30 hours/week to new projects. For full-time dedicated work, let's discuss timelines on a call.
Yes — I'm NDA-ready and can sign yours before our first technical discussion. Confidentiality is standard in all my enterprise engagements. I also have a mutual NDA template available if you need one.
A freelance developer writes code to spec. I architect the spec itself — identifying the right patterns, preventing costly mistakes, and designing systems that your team can maintain long after I'm gone. I've led teams of 15+, shipped national-scale infrastructure, and reduced 82-second queries to under a second. You're not hiring hands — you're hiring judgment.
