Smooth Finish Drywall & Painting

Smooth Finish Drywall and Painting homepage: nav, logo, hero headline, trust stats, and call-to-action

Smooth Finish is a drywall and painting contractor in Fort Wayne with 35+ years in the trade. They came to us off a rented website builder that left them with nothing they actually owned. We built them a fast, polished site — real photos of their own work, a curated project gallery, and a contact form that drops leads straight into the owner’s inbox — and handed over every key. It’s theirs outright, no monthly platform fee, no lock-in.

What Was Delivered

  • Custom website built around their real jobs and photos
  • Self-serve photo & before/after gallery uploader
  • Contact form delivering leads straight to the owner
  • Owned outright — no rented builder, no monthly lock-in

Bonus Round Arcade

Bonus Round Arcade website: branded navigation and a neon-lit photo of the arcade's skee-ball machines

Bonus Round is a family entertainment venue in Decatur, Indiana. We delivered a complete website and the digital infrastructure around it, with the owner holding every key from the start. The site does its job, looks the way the venue feels, and nothing about the build is locked away from the people who own it.

What Was Delivered

  • Custom website built for the venue
  • Owner controls every account from day one
  • Local-search visibility configured
  • Source, credentials, and documentation delivered at close-out

Custom Software — Independent Academic Publisher

Editorial & Open-Review Pipeline

Independent academic publishing platform built by 3Rivers WebTech
Independent academic publisher site: branded navigation, research-program cards, and an editorial case study

The client publishes academic research and wanted out of expensive subscription publishing platforms. We built the whole system — author submissions, AI-assisted review, scoring, editorial sign-off, publication, and archival — from scratch. Owned outright. The same kind of platform a university normally rents for six figures a year, built once for a fraction of the cost.

The technically interesting part isn’t that it uses AI. It’s that the AI doesn’t leak. Author names are stripped before the review panel ever sees the paper, and if anything looks wrong with that stripping the pipeline halts itself rather than guess. Most off-the-shelf “AI tools” can’t promise that. This one does, because it was built to that standard from the first line of code.

What Was Built

  • Complete publishing platform, owned outright
  • AI-assisted review with built-in author privacy
  • Halts itself if anything looks wrong (no silent leaks)
  • Membership and public verification endpoints
  • Same capability universities rent for six figures a year

Custom Software — Citation & AI-Grounding Infrastructure

CiteStamp

CiteStamp logo CiteStamp
CiteStamp website: citation-signing platform with value propositions and feature cards

Outside the journal system a reference list is just text — Google Scholar hands you a number, and the AI summarizing your field is guessing. CiteStamp rebuilds the citation from the ground up: every reference becomes a signed, public, typed claim — this paper supports mine, refutes that result, extends a method — welded to the author’s name on a permanent, tamper-evident log. Scholarly provenance you actually own, and a ground-truth layer that machines can check.

What It Does

  • Write — a citation picker at the cursor: type @cite, search live scholarly data, and drop a formatted reference (Markdown/BibTeX) without your draft ever leaving the browser
  • Find & check cites — ask a live citation graph what supports, refutes, cites, or references any paper — typed relationships, not a flat count
  • Attribution that sticks — every claim signed under your ORCID identity, timestamped and chained on an append-only public log (CC0, forkable, impossible to quietly edit)
  • Grounding for AI — a hosted MCP server and REST API that agents query before they cite, with human-signed and machine-inferred evidence kept strictly apart

Why It Matters

That last one is the breakthrough. Language models invent citations constantly, and the fake bibliographies keep shipping. CiteStamp is the live endpoint an AI consults to verify a reference against a signed, attributable record instead of guessing — turning “trust me” into something checkable. It’s open infrastructure (no token, no gatekeeper, no journal required) that puts human scholarship and AI on the same verifiable graph — and we designed and built the whole stack end to end, from the cryptographic signing to the public log to the grounding API.
