Your clinical work is solid. Your systems are holding you back.
I'm Chaim Tesser. I help behavioral health agencies fix the technology underneath the business so the operation runs on systems instead of memory.
Lakewood, NJ · Serving behavioral health agencies nationwide
I know the operation, and I can build the systems under it.
I've spent my career inside systems that can't afford to go down. Backend, infrastructure, and integration work at Capital One and beyond: migrations that had to hold, services handling roughly a million requests a day at 99.8% uptime, maintenance cut in half.
My background in behavioral health is deepest in ABA, which has some of the hardest operational plumbing in healthcare. Intake that leaks, authorizations that expire, audits that require stitching four systems together by hand. That experience carries directly into mental health, substance use, pediatric therapy, and multi-service agencies.
Book a call →Most agencies run on tools that were never built for this work.
Leads live in an inbox. Authorizations sit in a spreadsheet. Notes, scheduling, and billing each live somewhere different. It holds together because a few people carry it in their heads. That worked when margins were healthy. Under reimbursement pressure and surprise audits, the gaps between systems are where the money quietly goes.
Leads that vanish
Families wait on a callback and go with whoever answered first.
Authorizations that expire
No system runs the clock, so services get delivered that can't be billed.
Audits you can't answer fast
Proving a claim means stitching four systems together by hand, under a deadline.
A business that only works when you're in it
The operation depends on memory, not systems, which caps how far you can scale.
Why a technology leader, not another consultant.
I know the operation, not just the software
A CRM consultant knows a tool. I know why intake stalls, how an authorization expires, and what a clean clinical handoff needs, then I decide what to build around that.
Real engineering behind it
Backend, infrastructure, and integration work at Capital One and beyond. When your systems need to actually connect and hold up, that is the background that matters.
No vendor kickbacks on advice
When you hire me to help you choose, I take nothing from any software company. My only job is the system that fits you.
Built for where the field is going
Reimbursement pressure rewards efficiency. Audits reward clean records. Buyers pay premiums for agencies that run on systems. I build the infrastructure all three demand.
What the engineering background looks like in practice.
Migrating mission-critical services to serverless
Led the migration of four container-based services to AWS Fargate. Mentored junior engineers and covered a 3-month managerial gap without losing delivery momentum.
The takeaway for agencies: I lead work where systems have to hold, then bring that same rigor into operations that can't afford billing or authorization downtime.
Uptime on services handling ~1M daily requests, with maintenance time cut by 50%.
Rebuilding platforms and killing integration errors
Migrated custom CMS apps from .NET Framework to .NET Core and designed a custom tax integration for international clients, resolving complex VAT issues end-to-end.
The takeaway: I know how to untangle systems that grew organically and make them reliable without disrupting the business.
Tax-related integration errors after rebuild, down from chronic month-end pain.
Fixing the technology underneath the agency
Working with agencies on intake leakage, authorization tracking, audit readiness, and the integrations between clinical, ops, and billing tools. Deepest experience in ABA, applied across behavioral health.
The focus: systems the business can run on, without forcing a rip-and-replace when the current stack can be made to work.
Build the infrastructure reimbursement pressure, audits, and buyers all demand.
