Kalisada / Spreadsheet Developer

Spreadsheet developer for hire · Phoenix, AZ

Hire a developer who fixes spreadsheets for good.

Broken formulas, fragile files, spreadsheets only one person understands — I repair them, rebuild them, and when a spreadsheet has outgrown Excel, I turn it into a simple app your whole team can use. I’m a full-stack developer — I fix what can be fixed, and rebuild what Excel can’t handle anymore.

Sound familiar?

The one-person file

Only your estimator knows how it works. When they're out — or gone — bids stop, and nobody dares touch the formulas.

The silent break

Someone sorts a column, a formula quietly dies, and you find out when the numbers go out wrong. One bad cell can be real money.

The version mess

FINAL_v14_(2).xlsx, emailed around, edited by three people. Nobody's sure which numbers are current.

What I do

Spreadsheet repair & cleanup — broken formulas, slow files, version chaos, fixed at a flat rate.

Spreadsheet-to-app rebuilds (flagship) — when the file has outgrown Excel, I turn it into a simple private web app: same logic, math locked down, one current version, whole-team access. One-time build fee, no per-seat software subscription.

Specialty: construction subcontractors — estimating, bid tracking, and job-costing files are where I do my best work.

How it works

Free 15-minute review. Send me the file or share your screen. I'll tell you honestly whether it's fixable in Excel or worth rebuilding — no pitch if it's not.

Fixed quote. One number for the whole build. No hourly meter, no surprises.

Build and switch-over. Most rebuilds are live in 2–4 weeks. Your crew keeps working in the old file until the new one is proven against it.

Typical build: one-time fee, quoted per project. Small monthly fee covers hosting, backups, and support — cancel anytime, and your data is always yours.

Call or email. Local Phoenix developer — you'll deal with me directly, start to finish.

Have the file handy? Email it over — or a copy with fake numbers if it’s sensitive — and I’ll take a look within one business day.
