I will build a react web app or pwa with local browser storage
Fernando Sala
About this gig
Turn one small workflow into a useful browser app. I build focused tools with real interactions, responsive layouts and a scope we can test together. Development uses AI assistance, technical validation and a final human review before delivery.
Basic: one screen for a small calculator or editable list.
Standard: up to two views with create, edit, remove, search, three statuses and JSON export.
Premium: up to three views, a second related entity, print output and an offline PWA shell where supported.
These packages are for one person's local browser workspace. Data stays in that browser and may be cleared; there is no login, cloud sync or shared database. Daybook and Fieldnote are original functional demonstrations. Source code and usage notes are included. Payments, sensitive-data systems, native mobile apps, app-store submission, paid APIs and ongoing hosting are excluded. Message me first with your workflow, fields, sample data and acceptance criteria to confirm fit.
Revisions: Basic includes 1 round; Standard and Premium include 2.

I'm Fernando. I build responsive websites, React landing pages, web apps and PWAs with AI assistance, technical checks and human review. Explore my 3D demos and real self-owned projects: LaunchLens, Pais em Dia and Senda Practica. I also assess Wix websites, Shopify stores and iOS/Android apps for the App Store and Google Play under a separate custom scope. Feasibility, build/testing access, client accounts, platform fees and store review are checked before an offer. Send your goals, features and deadline to define the right scope.

FAQ
Do you use AI?
Yes. I use AI-assisted development, technical checks and human review. If your project restricts AI usage, please discuss that before ordering so I can confirm whether our workflow is compatible.
How many revisions are included?
Basic includes 1 round; Standard and Premium include 2. A consolidated set of changes within the agreed design and functionality. New pages, features or a different direction require a separately agreed extra. Reproducible defects within the scope are corrected without using a revision round.
Are hosting and domain included?
No. You own and pay for your domain, hosting and third-party services. Deployment compatibility and any assistance are agreed before the offer.
Are the portfolio projects real client work?
Some entries are self-initiated demos with fictional brands and sample data. LaunchLens, Pais em Dia and Senda Practica are real self-owned projects. Each case explains its scope; no client commissions or commercial results are implied.
Can these apps be used by a team?
The launch app packages use local browser storage for one person. Accounts, cloud sync, multi-user permissions and shared databases require a separate project assessment.
Will the app appear in an app store?
No. A PWA is a website with supported installation/offline capabilities. Native apps and App Store or Google Play submission are outside these packages.
