Who this is for
This might be you.
Client onboarding is inconsistent and manual.
Every new client is a slightly different experience depending on who handles it. Some things get explained twice. Others get missed. There's no repeatable path.
You can't see across all your engagements at once.
What's due this week? Which clients are waiting on something from you? The answers exist — in different inboxes, different folders, different people's heads.
Billing is a manual process nobody enjoys.
Time tracking is inconsistent. Invoices get assembled from notes. Approvals take follow-up. Every part of billing involves more people-time than it should.
The approach
How I work in this space.
Map the full client lifecycle before designing anything.
Professional services firms have complex, relationship-driven workflows. I spend time understanding the full engagement lifecycle before proposing a system.
Build client-facing tools that reflect your brand and professionalism.
A portal that looks like an afterthought reflects on the firm. Client-facing tools should feel as considered as everything else you deliver.
Give your team visibility without adding overhead.
The goal is to reduce time spent chasing status — not to add a new system everyone has to update. I design for both the manager who needs the overview and the person doing the work.

Common questions
Before you reach out.
Do you build for specific practice areas?
I've built for legal, financial advisory, consulting, and accounting firms. The common thread is client relationships, document workflows, and billable time. If that's your world, the pattern applies.
Can the portal connect to our document management system?
If your DMS has an API, yes. I'll assess integration options during discovery.
What about e-signatures?
I integrate with established e-signature providers — DocuSign, HelloSign, Adobe Sign — rather than building that from scratch. You get a compliant, proven solution connected to your portal.
We have confidentiality requirements. How do you handle those?
Access controls, audit logging, and data handling are built in from the start — not added after the fact. I'll ask about your specific regulatory context during discovery.
