Software Consulting · South Africa
Software that grows with your business.
Kirschbaum is the practice of Wilhelm Kirschbaum — senior, hands-on engineering and technical strategy for teams that need to ship something real. No layers, no hand-offs: you work with the person doing the work.
Services
Four ways I help teams move.
From a single architecture review to embedded delivery — scoped to what you actually need.
Product Engineering
Web and mobile products built to last — from first commit to production. Clean architecture, sensible tooling, and code your team can own after I leave.
Data & AI
Turn data into decisions. Pipelines, dashboards, and LLM-powered features that earn their keep — pragmatic, measured, and shipped to real users.
Technical Strategy
Architecture reviews, roadmaps, and the hard calls — made with you, not for you. A clear path from where you are to where you need to be.
Team Augmentation
Senior hands when you need them. Embedded delivery and mentorship that lifts the whole team — without adding permanent headcount.
Approach
Small, senior, and built to hand over.
The way I work is the product. Three commitments on every engagement.
One senior partner
You brief the person writing the code. Decisions happen in the room, not three emails later.
Right-sized solutions
No resume-driven architecture. I build the simplest thing that solves the problem and scales when you do.
Yours to keep
Documented, tested, and handed over cleanly — so your team is stronger when the engagement ends.
About
I’m Wilhelm Kirschbaum, a software consultant with years of building and shipping products across the stack. I started Kirschbaum to do the work I care about — close to the code, close to the client.
“Kirschbaum” means cherry tree. The mark is a branch that doubles as a logic tree: things that grow, and decisions that branch. That’s the work.
