15 Side Project Ideas for Solutions Architects in 2026

By Cristian Lascu · The Sovereign Technologist

Solutions architects are in a rare position: they understand both business problems and the technical systems that solve them. That dual perspective is genuinely scarce, and it's the basis for some of the most valuable independent work available to technical professionals. These side project ideas help you convert architecture expertise into income that doesn't depend on a single employer.

Pro tips

→Your most valuable skill isn't your technology knowledge — it's knowing which technology NOT to use. Sell vendor-neutral objectivity explicitly.
→Architecture diagrams are your portfolio. Before pitching any client, have 3–5 anonymised architecture case studies ready to share.
→The fastest path to first revenue is a productized review: fixed scope, fixed price, delivered in 5 days. You already know how to do it — just package it.
→Your existing professional network is your first sales channel. Tell 10 people what you're offering. One will know someone who needs it.

Frequently asked questions

What are the best side projects for solutions architects?

Architecture reviews as productized services, technical writing for vendors, cloud migration advisory, and online courses consistently work well because they directly leverage the skills you use daily — without requiring you to build anything new.

How do solutions architects find freelance clients?

Start with your existing network. Every company you've worked with, every vendor you've partnered with, every colleague you've advised — these are your first opportunities. LinkedIn outreach to engineering leaders and CTOs at growth-stage companies also works well.

How much can a solutions architect charge for independent work?

Architecture advisory retainers typically run €5,000–€15,000/month for senior architects. Productized reviews start at €3,000–€7,000 per engagement. Fractional Chief Architect roles can command €10,000–€25,000/month depending on scope and company stage.

Can I do architecture consulting without leaving my job?

Yes — especially via productized services and advisory roles that require 5–15 hours per week. Check your employment contract for IP and non-compete clauses, and avoid clients in your employer's direct market.
