Hourly IT and software engineering
Nothing broken, nothing billed.
Windows Server, Cisco networking and .NET (Microsoft platform for business software) development for businesses that need a real engineer, not an outsourcing contract. $150 an hour, no contract, no monthly fee.
Same-day remote · Onsite from Polk County to Orlando · English / español
Check before you call
- Who answers. Andres Diaz. His day job, lead developer on enterprise Active Directory (the Windows service that holds users, computers and logins) and Microsoft 365 software, is on LinkedIn. You get him on the phone, not a reseller. When the work gets done
- Work you can open. ClickPro and CheckSumPro, built and run by me; open them and look around. What each one is
- Who you pay. Inexcelsis, LLC, doing business as NanoScript, Winter Haven, Florida.
One rate, infrastructure or software
$150
per hour. One hour minimum per request, then 15-minute increments. Two hours minimum onsite. Same rate after hours and on weekend cutovers (the moment the old system goes off and the new one goes live).
What I get called for
The server, the switch, and the app that talks to both.
Most people who touch your network cannot write software, and most people who write software have never configured a switch. I do both, which is usually what the problem turns out to need.
Servers and identity
Windows Server and Active Directory
Server 2016-2025 · AD (Active Directory: the Windows list of users, computers and logins) · Group Policy (settings sent to every Windows computer from one place) · Hyper-V (Microsoft software that runs virtual computers on one server) · M365 hybrid (Microsoft 365 with part of it still on your own server) · SQL Server (the database software most business systems keep their data in) · backup and restore
- Our server goes out of support this year and we have no plan.
- The person who built our domain is gone and nobody has the admin account.
- Logins take four minutes since we opened the second office.
- We are half migrated to Microsoft 365 and stuck in the middle.
- The backups say they ran. Nobody has ever restored one.
- Everyone can see the payroll folder and we do not know why.
Networks
Networking, firewalls and Cisco switches
Cisco switching · VLANs (separate networks that share the same switches) and segmentation (splitting the network so one device cannot reach everything) · site-to-site and remote VPN (an encrypted link between offices, or from home to the office) · firewalls (the device that decides what traffic gets in or out) · wifi · QoS (quality of service: calls and video get the bandwidth first) · cutovers
- We move offices in six weeks and it has to be live on day one.
- The network drops for ten seconds a few times a day.
- Cameras, card readers and guest wifi are all on one flat network.
- Our insurance questionnaire is asking things I cannot answer.
- The two offices need to see each other without the cloud in between.
- Nobody knows what is plugged into what, anywhere.
Software
C#, .NET, PowerShell and REST
.NET Framework to .NET 8 · PowerShell (Microsoft scripting language for automating Windows and 365) · Microsoft Graph (the way programs read and change Microsoft 365 mail, users and files) · REST (the common way web systems talk to each other) integrations · SQL · CI (continuous integration: every change is built and tested automatically) with rollback (going back to the last version that worked)
- The app our business runs on was written by someone who left.
- Someone spends a full day a week copying data between two systems.
- We need these two systems to talk and neither vendor will help.
- Setting up a new hire takes two hours of clicking.
- The report the owner asks for takes a week to produce.
- We pay for software with an API (the doorway a program offers to other programs) that nobody here can use.
Not sure which of the three it is? Start from what happened instead; each one says where it usually lands. Or skip straight to the form and pick "Not sure yet". Sorting that out is part of the free first answer.
Nobody calls an engineer because they feel like it.
Something forces it. If one of these is true for you right now, the clock is already running.
Deadline
End of support
A version going unsupported turns a maybe into a date on a calendar.
Usually lands in: servers, sometimes software
This is us: end of supportPeople
Someone left
The person who knew it is gone, and so are the passwords and the reasoning.
Usually lands in: servers and identity
This is us: someone leftPremises
A move or build-out
New space, new cabling, new switches, and a day when it all has to work.
Usually lands in: networks
This is us: a move or build-outPaperwork
Insurance or an audit
A questionnaire asks about segmentation, MFA (multi-factor sign-in: a code or an app on top of the password) and backups, and the honest answers are bad.
Usually lands in: networks and servers
This is us: insurance or an auditIncident
A scare
Ransomware, an outage, or a close call that made the owner ask what else is exposed.
Usually lands in: servers and networks
This is us: a scareGrowth
A second location
What worked for one office quietly stops working for two.
Usually lands in: networks and identity
This is us: a second locationDrag
A manual process
A person became the integration between two systems, and they are now the bottleneck.
Usually lands in: software
This is us: a manual processChange
An acquisition or split
Two domains, two sets of licenses, two of everything, and one deadline.
Usually lands in: servers and identity
This is us: an acquisition or splitThe bill
Your IT bill the month nothing broke.
You are probably paying a monthly number right now whether anyone touched your systems or not. I charge for hours worked. A quiet month costs nothing, and I would rather have quiet months.
Hours worked: 0.0 $0.00
Four months with nothing to fix, and four invoices for $0.00. On a managed contract all twelve cost the same.
| Compared on | A managed contract | NanoScript |
|---|---|---|
| A month with no issues | Billed in full | $0 |
| Priced per | User, device or endpoint | Hour worked |
| Who shows up | Whoever is on the schedule | The engineer who did the last one |
| After hours | Premium rate | Same $150 |
| Leaving | Notice period, then a migration | Stop calling. Your documentation is yours. |
The trade: No monthly fee also means no contracted 24/7 response. What you get instead: first call for people I already work with, an environment documented well enough that any competent engineer can act at 3am, and a straight answer when a job needs a staffed help desk rather than one person.
Proof you can check
Three systems, start to finish.
Client work stays confidential, so these are systems I built and run myself. Two you can open right now; the third sits behind a sign-in on purpose.
Software and payments
Bookings and card payments for clinics and salons
- The job
- Many businesses on one system, each with its own staff, calendar and card payments.
- What it took
- Built and run by me; the software it is made with is on the list of systems.
- Where it stands
- Live at clickpro.app; the screenshot above is from October 2026.
Data and reconciliation
Bookkeeping and reconciliation for small businesses
- The job
- Financial records for more than one business that have to add up.
- What it took
- Built and run by me; the software it is made with is on the list of systems.
- Where it stands
- Live at checksumpro.com; the screenshot above is from October 2026.
- Old tablet, no modern web
- Stream, after sign-in
- Modern browser, isolated VM (virtual machine: a computer that runs as software on another one)
The VM runs in Hyper-V on my hardware.
Servers and isolation
A modern browser for devices too old for the web
- The job
- Old tablets and computers that current websites no longer work on.
- What it took
- A browser running in a Hyper-V virtual machine on my own hardware, streamed to the old device.
- Where it stands
- It sits behind a sign-in, so ask and I will show it to you on a call.
How this site ships
Tested before release, checked after.
The steps are written into this site's own code: tests run before every release, an automatic visit to the public address follows it, and a failure emails me. The domains on the list of systems are public, so you can look up their DNS (the internet address book that points your domain at your services), TLS (the encryption behind https) and mail records yourself.

Who you get
Andres Diaz, the engineer who answers.
By day, lead developer on enterprise Active Directory and Microsoft 365 governance software, which means the systems you run are the systems I build tools for. On my own time I build and run the systems on the work page. I work in English and Spanish, and I write everything down so you are never locked in to me.

For MSPs (managed service providers: IT companies that look after other businesses) and IT companies
Your overflow, under your name.
Overflow, escalations, AD cleanups, switch configs and the PowerShell your techs do not write. It is some of my favorite work.
White-labeled (done under your company name, not mine)
I work as part of your team.
Your name on the work. I bill you, and you bill your client.
Same rate
$150 an hour, nothing on retainer.
One hour minimum per request, then 15-minute increments.
Hands off
I never approach your client.
Not during the job and not after it. The relationship stays yours.
Tell me what is in front of you.
A sentence is enough. I will tell you whether it is an hour, a weekend cutover, or something you should not do at all. That answer is free.
- 01You call, text, email or use the form below and describe it in plain words. No ticket portal, no account to create.
- 02I reply the same working day and tell you what I think it is.
- 03Small things I fix on the spot at $150 an hour. Bigger ones get a paid assessment and a fixed quote before any work starts.
Who reads it: Andres Diaz, the engineer who would do the work.

English and Spanish.
Questions I get asked.
- What does it cost?
- $150 per hour, with a one hour minimum per request and 15-minute increments after that. Onsite visits start at two hours, because the travel costs you either way. Several small things handled in one call are one request, not three. No contract, no monthly fee, and no premium for after-hours or weekend cutovers. Larger projects are quoted fixed after a paid assessment, so you know the number before the work starts.
- What if I need someone at 3am?
- I am one person, so there is no contracted 24/7 response. Existing clients get first call, and I document environments well enough that any competent engineer can act during an incident. If your business genuinely needs round-the-clock staffed coverage, I will tell you that rather than sell you something thinner.
- Do you work remotely?
- Most of it, yes. Onsite across Polk County and the Tampa to Orlando corridor, with travel quoted at cost and approved before I book anything. When hands are needed in the building, an office manager holding a phone is usually enough and costs you nothing in travel.
- Do you speak Spanish?
- Yes. English and Spanish, with your team and in the documentation I leave behind.
- You also work as a lead developer. When does my work get done?
- You get a reply the same working day. Scheduled work is booked at a time we agree on, and cutovers usually belong after hours or on a weekend anyway, at the same $150. If something is down right now, call, or tick the box on the form, and it is the first thing I look at.
Something in front of you right now?
