§ A consulting practice for general contractors
Custom software for builders who’ve outgrown the box.
Jason Park Consulting designs and builds tailored software and AI tools for Bay Area general contractors — by someone who’s worked both sides of the trailer.

§ 01 — The shift
Your software is renting your data back to you.
Procore, Kahua, Autodesk Build — they each ask you to remodel your business to fit their structure. Your RFI process becomes their RFI process. Your daily logs become their template. The platform wins. Your standards lose.
For routine work, that trade is fine. But the work that actually wins jobs — the way your PMs run a buyout, the spreadsheet a senior estimator has refined over fifteen years, the close-out package your owners actually like — that work doesn’t fit in a settings panel.
What used to require a software team to address now takes one consultant and a few weeks. AI changed the math. Custom is back on the menu.
The contractors who realize this first will spend the next five years compounding small advantages their competitors can’t copy.
§ 02 — Services
Three ways I plug in.
Custom software
Targeted internal tools that fit the way your team already works. Bid trackers, schedule tools, daily-log automation, dashboards your PMs will actually open. Built lean, owned by you.
AI integration
Practical AI applied to specific bottlenecks — extracting data from RFIs and submittals, summarizing meetings, drafting stakeholder updates, surfacing risk in your bid pipeline. No chatbots in search of a problem.
Tech advisory
When you’re evaluating a platform, scoping a build with a vendor, or deciding whether to build vs. buy — a second set of eyes that knows the field and the code. Hourly or retainer.
§ 03 — Background
Both sides of the trailer.
Most software people who say they “understand construction” have read about it. Most construction people who say they “understand software” have an opinion about Procore.
I’ve spent [TODO: X years] in the field — [TODO: brief, specific sentence about the field experience]. And [TODO: Y years] building production software, most recently [TODO: brief sentence about software work].
That overlap is rare. It means I can sit in a preconstruction meeting and a code review the same afternoon and not be the dumbest person in either room. It means the tools I build don’t need to be translated for the people who use them — because the person building them already speaks the language.
The best construction software gets written by people who’ve stood in the mud.
§ 04 — Engagement
A short, structured way to start.
- 01
Discovery call
free, 30 minWe talk through what’s slowing your team down. No deck, no demo — just questions. You leave with a written summary of what I’d build and what it would cost, even if you don’t hire me.
- 02
Scoped pilot
2–4 weeks, fixed feeOne real problem, solved end-to-end, deployed to a real user. Fixed scope, fixed price. If the pilot doesn’t earn its keep, we shake hands and move on.
- 03
Build engagement
project or retainerIf the pilot lands, we expand. Either project-based with milestones, or a monthly retainer for teams that want ongoing capacity.
- 04
Handoff
Everything I build is yours. Code in your GitHub, deployed to your infrastructure, documented for your team. No vendor lock-in. If you hire your own engineer in year two, they should be able to pick it up in a week.
§ 05 — Capability demos
Things I’ve built that show what’s possible.
These aren’t products for sale — they’re working demos at jasongpt5n.com, built to show what a contractor’s tooling can look like when it’s tailored. Each one targets a real workflow. None of them required an enterprise license or a six-figure implementation.
Bid intelligence agent
A senior estimator’s brain on call. Pulls live pipeline data, bid history, and market signals to support go / no-go decisions.
View demo →Schedule delay simulator
Drop in a CPM schedule, model a delay on any activity, see the blast radius across the critical path and total project cost in real time.
View demo →Stakeholder action items
Paste meeting notes or upload a transcript. Get back a clean table of who owes what, due when, sortable and exportable.
View demo →All of these were built solo, in weeks not quarters. Yours could be too.
§ 06 — Get in touch
If something here sounded useful, the next step is a 30-minute call.
No pitch deck. No discovery questionnaire to fill out. Just a conversation about what your team is doing now, what’s clunky, and whether I can help. If I can’t, I’ll tell you who can.
