Architectural wisdom for mission-critical systems.

Molls and Hersh, LLC builds web applications and the iOS and Android apps that go with them — one architecture, one team, every screen. Thirty years of .NET engineering stands behind it, alongside our own developer tools, including Work Tunnel, live now. Engineered for certainty.

Your architectural partner, your way

Embedded Expertise

~60% of our work

We act as a pivotal, subcontracted extension of your existing team — architect-level leadership and senior .NET development that plugs into your onshore, offshore, or outsourced workforce. Your on-demand force multiplier.

Turn-Key Solutions

~40% of our work

You have a brilliant idea to address your business's unique needs. We explore that vision with you, map every detail together, then take complete ownership of architecture and implementation to bring it to life.

From idea to deployed →

Web and mobile, built as one system

Most of what we do is exactly this: a web application and its companion iOS and Android apps, delivered together as one product — not three projects that happen to share a logo.

One architecture, not three

The website and the mobile apps share the same C# domain model and the same API. Business rules are written once and behave identically on every screen — a phone, a tablet, and a browser cannot disagree about what your data means, because there is only one implementation of it.

How we build for every screen →

One partner, start to finish

No web agency to coordinate with a separate app shop, no integration blame to arbitrate, no feature that ships on the site months before it reaches the phone. Discovery, architecture, both platforms, deployment, and support come from one team — accountable for the whole result.

Core disciplines

.NET architecture consulting

Legacy modernization, multi-tenant SaaS design, and system blueprints that hold up under audit — and under load.

Custom enterprise solutions

Bespoke applications on .NET, Blazor, and MAUI, taken from first commit through production hosting and support.

Agentic AI engineering

LLM- and MCP-powered systems that work inside real engineering constraints — agents as digital workers, not demos.

Products

New to the AI vocabulary?

AI Chat, automated funnels, MCP, RAG — these terms are the new currencies of competing online. We keep a plain-language glossary so you can walk into any conversation fluent.
