I build repeatable construction estimating systems to make takeoffs, pricing, and proposals faster and more consistent. The workflow organizes quantities, labor, materials, subcontractor costs, margins, and proposal information in one place—reducing duplicate entry and creating a cleaner handoff from estimate to awarded project.

A client gave this idea the green light before I even started building it.
Been using AI a lot lately to prototype ideas early, show the direction, and make sure we’re aligned before jumping into the actual build.
Such a good time saver.
Fieldwork now works from request to approved quote.
Try the demo: https://launchinseven.com/samples/fieldwork
Enter a fictional service request, see the itemized estimate, then open Operations to edit the quote, review it and export a printable quote or CSV. Records survive a reload in your browser. The demo uses fictional data and local storage; a shared live system would need its own agreed backend and access controls.
The point is to make a business workflow concrete enough to test: what the customer enters, what the team reviews, what changes status and what leaves the system.
I direct scope and review; GPT-6 Astra handles implementation and many checks. This is an original working sample, not a paid client case.
If an existing web workflow is causing friction, message me on Contra with the URL or redacted screenshots and what should happen. We can agree a small paid first milestone—such as a documented workflow review or a defined interface fix—with its deliverable, fee, inputs and timing confirmed before work.
I'd keep a short change history beside the itemized estimate, so the team can see what changed before approval and which version was exported.
Building reliable backends is what I enjoy most.
I work with Python, FastAPI, PostgreSQL, SQLAlchemy, Docker and REST APIs, building backend systems that are clean, testable and easy to extend.
I can help with:
• REST API development
• PostgreSQL & database integration
• JWT authentication and RBAC
• Backend debugging and bug fixing
• API integrations and automation
• Docker setup and automated testing
I’ve also built projects involving e-commerce workflows, payments, inventory, document processing, analytics, webhooks and workflow automation.
If you’re building a product, improving an existing backend, or need help fixing something that just refuses to work — feel free to reach out.
Available for freelance backend projects.
