Technical Consulting & Architecture Reviews

Get a clear decision basis in 2–3 weeks

Architecture Review Independent Advisory Legacy Modernisation Make-or-Buy

Complex technology decisions carry real business risk. I provide independent advice, without vendor interests or agency dynamics, to help you make informed choices on system selection, architecture and investment.

Technology strategy & system selection: I assess make-or-buy decisions, compare platforms and evaluate project feasibility. You get a clear recommendation with the reasoning behind it, not a slide deck full of options.

Architecture and code reviews: I audit existing Shopware, Symfony and cloud-native systems to identify risks, technical debt and improvement opportunities. A typical engagement delivers a written report with a prioritised action plan and a realistic roadmap your team can act on immediately.

Technical product ownership: In complex projects I can act as the technical counterpart to business stakeholders, translating requirements into architecture decisions and holding quality accountability across delivery.

What clients say

I am pleased to give my explicit recommendation for Jeff, whom I had the pleasure of getting to know as an external consultant and product owner during our collaboration.

Jeff stood out above all through a collaboration as equals. Communication was consistently open, direct and solution-oriented. Even demanding or uncomfortable topics were addressed early rather than postponed. Our weekly syncs were thoroughly structured and well prepared, so decisions could be made efficiently within the meetings themselves. Particularly noteworthy is his ability to engage and align a wide range of stakeholders — from the development team through to senior business leadership — in a targeted way.

Professionally, Jeff combines deep technical understanding — particularly in Shopware and software architecture — with a clear strategic perspective. He operated with confidence at the interface between IT and business, balancing both perspectives without favouring either side. It was also remarkable how quickly he found his way into our domain and existing processes. Within a short time he was not only delivering hands-on but actively and productively contributing to further development. He formulated requirements precisely and prioritised them sensibly — even where the starting point was unclear or contradictory. Throughout, he consistently managed to reduce complexity rather than pass it on.

In terms of reliability and a results-driven approach, Jeff also set the standard. Agreed items were carried through consistently, with no need to follow up. Beyond that, he proactively contributed ideas, identified previously overlooked areas, and addressed potential risks early.

I would engage Jeff again at any time and recommend him without reservation — particularly for roles that call for deep technical understanding, structured requirements management and confident stakeholder communication.

I delivered several projects with Jeffrey Böhm as a developer and product owner, and was consistently won over by his technical and analytical expertise. His approach was always results-oriented and sustainable. I would work with him again any time and warmly recommend him for web projects.
