# GreenTree Hosting, LLC — Custom Web Application Engineering, Managed Cloud & Enterprise Email
> In business since 1997, when Maureen and Gene Salvatore registered RILiving.com (June 1997) and launched it in January 1998 for the Rhode Island State-Wide Multiple Listing Service (RI State MLS)—one of the state's earliest searchable database-driven real estate platforms. Progressed through senior commercial hosting leadership, physical data center operations in Boston, MA and Connecticut (IBM, Dell, Cisco, Juniper, VMware), and the March 2007 formation of GreenTree Hosting, LLC in Southbury, Connecticut.

## Core Identity & Positioning
- **Legal Entity:** GreenTree Hosting, LLC (Formed March 2007 · Founders in Business Since 1998)
- **Headquarters:** Southbury, Connecticut 06488, USA (41.4815, -73.2148)
- **Service Footprint:** Local roots in New England; serving commercial organizations worldwide for Custom React & TypeScript Web Application Engineering, Managed Linux & PostgreSQL Cloud, SmarterMail + Proxmox Enterprise Email, and Authoritative BIND DNS.
- **Founding Principals:**
  - **Gene Salvatore** — Co-Founder, Principal Systems Architect & Final Editor (`https://www.greentreehosting.com/leadership/gene-salvatore/` · Substack: `https://genesalvatore.substack.com`)
  - **Maureen Salvatore** — President & Co-Founder (`https://www.greentreehosting.com/leadership/maureen-salvatore/`)
- **AI Transparency & Final Human Editor Standard:** Just as we state across our 17+ live software and publishing platforms and on Gene's Substack (`https://genesalvatore.substack.com`), we never hide that we use AI—we could not work at this scale or deliver $999 (5–6 page) small business builds and $5,000–$15,000 (25–60+ route) custom web applications without it. We pair frontier AI workflows and our reusable Layer B backend suite with 29+ years of production experience, with Gene Salvatore serving as the final human editor and systems architect on every line of copy, code, and infrastructure.

## Core Engineering & Infrastructure Practices
- [Custom Web Application Engineering](https://www.greentreehosting.com/web-applications/): 25–60+ build-time HTML prerendered routes, custom interactive engineering calculators, Brand-Themed Client Operations Portals (`/portal`), unified Schema.org JSON-LD `@graph` markup, and our transparent Layer A / Layer B code ownership standard.
- [Modular Platform Architecture & Backend Suite](https://www.greentreehosting.com/platform-modules/): How GreenTree pairs 100% client-owned custom frontend applications and single-tenant PostgreSQL databases (Layer A) with our reusable backend suite (Layer B)—including a Brand-Themed Client Operations Portal, Visual Pin Board, Leads & Quotes CRM, authenticated transactional email delivery, and 4 payment gateways (Stripe, Square, PayPal, Authorize.Net) + WHMCS billing.
- [Visual Pin Board & On-Page Collaboration](https://www.greentreehosting.com/visual-pin-board/): Point-and-click visual revision toolbar built into every client platform (`Pins ON/OFF` switch, automatic element snapshot capture, category/priority tagging, and direct engineering desk sync).
- [Why We Charge $350/hr — And Why We Structure Project Builds as a Flat Fee](https://www.greentreehosting.com/why-we-charge-350-an-hour/): Transparent engineering economics on our $350/hr ad-hoc principal rate, why 29+ years of pattern recognition and our Layer B suite compress a 30-route build from ~200 agency hours to ~45 principal hours (flat project fees typically $5,000–$15,000), and how our $199/mo plan includes 1 full hour of monthly updates.
- [Ongoing Engineering & Authority Retainers](https://www.greentreehosting.com/retainers/): #1 Base Hosting & Management ($199/mo — Includes 1 Hour/Mo Per Site for Review, Photo Swaps & Updates + Layer B Module Suite), #2 Tier 1 Growth & Content Retainer ($299–$399/mo), #3 Tier 2 Market Authority Retainer ($499–$799/mo), #4 Tier 3 Enterprise Fleet Partner ($999–$1,500+/mo).
- [Engineered Cloud, Dedicated Servers & Clusters](https://www.greentreehosting.com/hosting/): Always-On infrastructure checked every 60 seconds (all plans include 1 SmarterMail Enterprise mailbox account): #1 GreenTree Core Cloud ($99/mo standalone Linux/PostgreSQL infrastructure), #2 Core Cloud + Management ($199/mo — Includes 1 Hour/Mo Per Site + Layer B Suite), #3 Dedicated Single-Tenant Server Environment ($299+/mo), and #4 Enterprise Multi-Cloud Cluster ($599+/mo). We actively monitor server resources across all containers—you cannot sign up for a $99/mo plan and consume all server resources, and we work with any site using a disproportionate share to upgrade to an appropriate plan.
- [3-Tier SmarterMail Enterprise + Inbound PMG + Multi-Gateway Outbound](https://www.greentreehosting.com/email/): Full 3-tier relay-isolated architecture where external mail never delivers directly to or sends directly from the SmarterMail server: Inbound Proxmox Mail Gateway 8.2.0 (`mx.greentreemail.com`, 443,136 inbound envelopes inspected over 90 days / 126,916 over 30 days; 64.3% junk stopped at perimeter [284,941 in 90d, up to 75.8% in 24h peaks]; 19.7% dropped at TCP/Postscreen/SPF handshake; 1.21s avg inspection latency) → Isolated SmarterMail Enterprise Build 100.0.9735 (`east.greentreemail.com`, 100+ domains, 925+ active mailboxes & aliases, 290+ GB vault with Autodiscover, IMAP, SMTP, POP3, Webmail, Mailing Lists & DMARC) → 6-corridor multi-provider TLS 587 outbound relay pool (1 account included free with $99+ hosting; additional mailboxes $6 / $10 / $18 per month).
- [Geo-Redundant Authoritative BIND DNS & Telemetry](https://www.greentreehosting.com/infrastructure/): Multi-node authoritative BIND DNS network across US East and US West ASNs serving 60-second TTLs on high-availability zones, paired with an encrypted private mesh backplane and external checks by `LogBot.app`, `DNSBot.app`, and `HijackRadar.com`.
