What's slowing you down?
Pick the one that sounds most like your week. We'll show you what we'd build first.
What we'd build
An AI assistant on your own data
It answers customers or staff from your policies, products and FAQs, shows how sure it is, and hands anything tricky to a person with a summary.
Services
What we build
From a full platform to a single automation, we build what your business needs. Each project starts with one problem that costs you time or money, and we scope the work around it.
Web apps and platforms
Marketplaces, customer portals, booking systems, and the other software your business runs on, designed and built around how you work.
Websites that convert
Clear, fast websites that explain what you do and make it easy for visitors to call, book, or buy.
AI assistants on your own data
A chat assistant for your customers or staff that answers from your own information first: products, policies, specs, and records. It stays inside guardrails, shows clear disclaimers, and runs under usage caps so costs stay predictable.
Automations and integrations
Connect the tools you already use so information moves between them without retyping, and routine steps run on their own with a person reviewing what matters.
Dashboards and plain-English reporting
Upload a sales export and ask questions in plain English, like “What was our best-selling product last quarter?” You get answers with charts, a quick summary of totals and top sellers, and a suggested action plan.
Internal tools for your team
Tools for support, hiring, and operations: a support agent that answers from your own documents and hands off to a person when unsure, hiring help from job post to candidate emails, and paperwork processing that pulls out key fields and flags what is missing.

Tell us what you needDigital Resilience
Keep working when the internet hiccups.
We design and build custom systems that reduce single points of failure in your CDN, DNS, cloud, identity, and payments, so an outage costs you less.
Recent outages have shown how concentrated modern internet infrastructure is. We build the practical redundancy that lets you degrade gracefully instead of going dark.

What we built
Species database
A searchable database of 508 freshwater and saltwater species, with care ranges and tank sizes.
Marketplace
Breeder storefronts, orders, and live auctions, including club auction nights.
Ask Echo, the AI guide
Powered by an engine called Poseidon, Echo answers from Aquacellum's own species data (temperature, pH, size, temperament) before general knowledge. It checks whether fish can live together and shows the numbers on a card, and it takes voice input.
Guardrails
- No medical diagnoses
- Clear disclaimers
- An hourly usage cap to control costs
Community
The Reef, clubs, and a leaderboard.
Installable app
Works offline, for tank logs at home and at shows.
Developer API
A developer API.
Results
Live in production on version 5, refined over five releases with the client's feedback. Breeder storefronts are actively listing and selling.
Demos
More we've built
A few examples of what we've built. Every client project is custom. All demos run on sample data. Two are online behind an access code, and we walk you through the rest live on a call.
LiveInsightFlow
Ask your sales data questions
Upload a sales spreadsheet and ask about it in plain English. It answers with charts, sums up totals and top products, and drafts an action plan. The sample data is a fictional three-location coffee shop.
Try the live demo: InsightFlow (opens in a new tab)Access code required. Book a call to get one.
LiveSupportForge
Support answers from your own documents
A support agent that answers from a business's own policies and product manuals. Each reply shows its confidence, and questions it cannot answer well are handed to a person with a summary.

TalentFlow
Hiring help, from job post to reply
Turns rough notes into a job post with screening questions, scores PDF resumes against the role with strengths and red flags, and drafts thank-you, offer, and decline emails. The current version is set up for golf course hiring.
ProcessPilot
Paperwork in, clean data out
Reads invoices, receipts, and onboarding forms, pulls out the key fields with a confidence score for each, and flags problems like a missing signature. Each document then moves through review to a suggested next step, such as an email draft.
PersonaForge
Customer personas and campaigns
Groups a customer list into four to six personas with pain points, buying triggers, and preferred channels, then drafts email, social, and SMS campaigns for each. The sample data is a skincare customer list.

About
Kevin McDermott, founder
Kevin is NYC-based and a builder first. He designed and built Aquacellum, now live on its fifth version, and every demo on this page.
He started Nexus AI Solutions to be what the web developer was for businesses in the early web: the person who builds whatever you need. Today that includes AI, built into the tools you use every day.
Our mission
Protect small and mid-size businesses through sovereignty and decentralization. Give them ownership of their systems, their data, and their intelligence — so they no longer depend on a handful of cloud providers to stay open or to think.
