Most ABA agencies struggle with broken systems. You don’t have to.
I’m Chaim Tesser. I help ABA agencies fix billing, credentialing and clinical reporting, and turn their technology into something they can actually trust.

Senior technology leadership without hiring a full-time CTO
I’ve spent my career inside systems that can’t afford to go down. I led the migration of container-based services to serverless, handling roughly a million requests a day at 99.8% uptime and cutting maintenance time in half. Before that, I built custom CMS and e-commerce solutions, and designed international tax integrations that reduced errors to zero.
Now I bring that same operator mindset to ABA. Because in this industry, when systems break, billing slows, staff get frustrated, and care is affected. That’s not acceptable, and it’s fixable.

With a Fractional Tech Leader, these turn from recurring headaches into operational wins.
Issues I usually find
- Billing doesn’t match clinical reality
- Credentialing scattered across spreadsheets and custom fields
- CR “works” but forces constant workarounds
- Payroll, HR and clinical systems don’t talk to each other
- No clear source of truth, just tribal knowledge
What you accomplish instead
- Billing & reports leadership can actually trust
- Credentialing, payroll and provider data in one usable place
- CR and related systems connected, no more workarounds
- A simplified stack that matches how your agency actually runs
- Stability that scales as you grow, no rip-and-replace
Reliable, operator-minded, and focused on outcomes
Reliability
I’m responsible for your technology outcomes. Each quarter you’ll get clear reports on what’s happening and a plan for the next 90 days.
Operator mindset
I don’t just think like a developer. I think like an operator, because in ABA, tech problems are billing, staffing and care problems.
Calm team culture
I create a collaborative, positive culture on your tech team and delegate to keep each person in their genius zone as much as possible.
What senior technical leadership 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 stepped in to cover a 3-month managerial gap without losing momentum on delivery.
The takeaway for ABA: I’m used to leading teams where systems have to work, and bringing that same rigor into agencies that can’t afford billing or CR downtime.
Uptime on services handling ~1M daily requests, with maintenance time cut by 50%.
Rebuilding custom platforms & 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 for ABA: I know how to untangle systems that have grown organically, and make them reliable without disrupting the business.
Tax-related integration errors after rebuild, down from chronic month-end pain.
Fixing billing, CR and credentialing end-to-end
Leading initiatives across ABA agencies to resolve billing, credentialing and clinical reporting issues. Collaborating with clinical, ops and finance teams to eliminate workarounds and make reports actually trustworthy.
The focus: clean reporting, streamlined workflows, no chaos.
