What I help with
Six areas where senior technical judgement changes the outcome. Most clients start with one and add others as the work evolves.
All servicesFractional CTO and technical leadership
A senior technical leader in your company a few days a month: owning architecture, the roadmap, hiring, and the conversations with your board.
AI and LLM integration
Production AI that earns its place: ambient AI, retrieval-augmented generation, agents, and clinical or enterprise AI with the guardrails your domain requires.
Healthcare software and EHR integrations
HIPAA- and PHIPA-aware architecture, HL7 and FHIR integrations, and connections to labs, pharmacies, and e-prescribing networks.
Software architecture and cloud
Architecture that fits your stage and scales with you: system design reviews, cloud strategy, reliability, security, and cost control.
Product and MVP development oversight
Get your first product built right, whether by your team or an agency: scope, technology choices, vendor selection, and quality control.
Technical due diligence
An independent assessment of a company's technology, team, and risks for investors and acquirers, delivered in plain language on your deal timeline.
Why CloudXChange
You're hiring a person, not a firm. The senior technologist you talk to on the first call is the one who does the work.
- Senior from the first hour
- No junior consultants learning on your time. You get years of experience building and leading software teams, applied directly to your problem.
- Hands-on, not hands-off
- I read the code, sit in the stand-ups, and draw the diagrams. Advice comes from looking at your systems, not from a slide deck.
- Independent advice
- CloudXChange isn't a dev shop, so there's nothing to upsell. When the right answer is to build less, hire someone else, or stop, I'll say so.
- Built for regulated work
- Deep experience in healthcare and AI, where privacy, safety, and integration requirements decide whether a product can launch at all.
How an engagement runs
Every engagement follows the same four stages. The length of each depends on what you need.
Step 1: Discover
We talk through your goals, your team, and your constraints. I review the systems and documents that exist and tell you what I see.
Step 2: Plan
You get a written plan: priorities, decisions, risks, and the order to tackle them in, with clear owners and timelines.
Step 3: Build
I lead the work alongside your team or your vendors: making decisions, reviewing output, and removing what's blocking progress.
Step 4: Scale
As things stabilize, I put in the process, hiring, and documentation that let the company grow without me, then step back.
What clients say
“Within a month we had an architecture we trusted, a hiring plan, and a board that finally understood our technology roadmap.”
“From architecture and engineering to execution and delivery, he demonstrated a rare combination of technical depth, strategic thinking, and accountability. They didn’t just “build what was asked” — they leaned in, asked the right questions, challenged assumptions when appropriate, and consistently brought forward thoughtful solutions that strengthened the overall product.”
“Ahmed redesigned our store’s website and took care of our SEO. The new site is fast and easy for customers to use, and people searching for electronics repair nearby are now finding us. It’s brought more customers through our door.”
