Web platform development in Miami
Plenty of Miami companies run one business across several countries: an operations team in Miami, support in Colombia, customers in Mexico and Brazil, and a single web platform that has to serve all of them. Each country arrives with its own rules about who may see which records, which documents a customer must upload, and what an internal user is allowed to approve.
We build those platforms as one codebase with the country treated as a first-class part of the data model rather than a filter added later. Roles and permissions are scoped per market, admin actions are logged with who did what and when, and customer onboarding can differ by country without forking the product. It is the same multi-tenant pattern we use elsewhere, applied to countries instead of customers.
Miami's software buyers tend to face south. Many of the companies that set up here in the last few years came for the same reason: it is where a US-incorporated business can sit next to its Latin American customers, investors and staff. Cross-border payments, remittances, neobanks, crypto infrastructure and the US arms of Latin American companies make up a large part of the local technology market, alongside real estate, hospitality and trade. The systems they need are rarely built for one country.
That shapes the work. Money movement is the core of the product rather than a feature bolted onto it: idempotent payment calls, a double-entry ledger, reconciliation jobs that compare your records against a partner's settlement file every night and flag the difference. The product has to handle Spanish and Brazilian Portuguese properly, validate local ID numbers and address formats, and settle through rails such as Pix in Brazil and SPEI in Mexico as well as cards. Crypto products add wallets, chain indexers and custody integrations, and the same principle applies: your database has to agree with the chain, and when it drifts, somebody needs a report saying where. Real estate, hospitality and trade bring their own version of the problem, usually a workbook that runs the business and quietly disagrees with its copies.
The hiring market has moved with the migration of finance and technology firms from New York and California. Built In puts the average base salary for a software engineer in Miami at around $145,000, and engineers who are bilingual and have shipped payments work are the hardest seat to fill. That is the seat we fill for a defined build: a payments integration, a reconciliation system, a second-country launch, or the months while a permanent hire is found. Work starts with a fixed-price two-week piece, and the code belongs to you from the first commit.
We move our working day for Florida. Four hours of every working day overlap with your morning in Eastern time, stand-up included, so calls, code review and decisions happen live with the engineer who writes the code. Everything else is written down where you already work, and runbooks and architecture notes are written as we go, so the next engineer who joins can read how the money moves.
We are the right fit for a defined build: a payments integration, a reconciliation system, a second-country launch. Senior capacity starts within days, the first piece is a fixed-price two-week engagement, and we can cover the months while a permanent hire is found. Agencies serving Miami's fintech, hospitality and retail brands can put the work under their own name.
Four ways this arrives.
We replace the role column with a permission model that can express teams, access to individual resources and roles the customer defines, add SAML or OIDC sign-in, and write the audit log their security questionnaire will ask about.
Or very nearly did. We find every query that can cross a tenant boundary, enforce the tenant in one layer rather than in every handler, and add tests that try to read across that boundary on purpose.
We build the admin side properly: search across organisations, an audited view-as-user mode, and screens for access and usage. Support stops asking an engineer to run a query against production every time a customer says something looks wrong.
An early Next.js app with auth stitched into middleware, a custom server, and a release process that lives in someone's head. We move it forward in small steps, with preview environments and a pipeline anyone on the team can ship from.
A Next.js platform scoped per organisation, where an administrator can view the app as any other user and each Tableau report opens only for people granted it.

How do you work with teams in Miami?+
We are in Bengaluru and move our working day for Florida, so four hours of every working day overlap with your morning in Eastern time, stand-up included. Calls, code review and decisions happen in that window. Everything else is written down in your own tools, whether that is Slack, GitHub or Linear, and the person on every call is the engineer who writes the code.
Can you build for Latin American markets as well as the US?+
Yes, and it is more than translation. Mexican and Argentinian Spanish differ, Brazilian Portuguese is its own language, and ID numbers, address formats, currencies and instalment payments all change by country. We design localisation into the first component, format money through the platform's own internationalisation tools, and integrate the payments provider you have chosen, with room for a second provider and local rails such as Pix and SPEI.
How does your rate compare to hiring in Miami?+
Built In puts the average base salary for a software engineer in Miami at about $145,000, before equity and benefits. Our published rate is $35/hour, or $5,400 a month for an embedded engineer, with a $5,000 minimum. There is no recruiting time and no employment overhead, and work starts within days of the call. The first piece is a fixed-price two-week engagement at $2,800, so you judge us on working code.
Can you work white-label for a Miami agency?+
Yes. Miami agencies regularly win fintech, hospitality and ecommerce projects that need more engineering than the in-house team can take on at once. We work under your name as part of your team, so your client deals with you and the work arrives as yours. The NDA comes before any specifics, the code belongs to the client from the first commit, and runbooks and architecture notes are written as we go.
What is wrong with a role column?+
Nothing, until you have more than one kind of customer. A role says who a user is; most real questions are about what they can do to one specific thing, inside one specific organisation. Encoded as role checks, every new requirement becomes a code change in many places. We model permissions as data, check them in one place, and test them like any other logic.
Should we use an auth provider or build our own?+
Use a provider for identity: passwords, magic links, SSO and multi-factor. It is a solved problem and getting it wrong is expensive. Authorisation, meaning what a signed-in user may do, is specific to your product and usually belongs in your own code and database. We wire the first to the second and keep the line between them clear.
How do you handle multi-tenancy?+
Usually one database with a tenant ID on every row, enforced in one place: Postgres row-level security, or a data-access layer every query has to pass through, rather than each handler remembering. A separate database per tenant is sometimes right, for one very large customer or strict isolation, and we will say if that applies to you.
Where does it get hosted?+
Wherever suits your team. Vercel is the least effort for Next.js and fine for most platforms. If cost or long-running background work make that awkward, we run it in containers on Railway, AWS or your own Kubernetes. The repository, the cloud accounts and the bill are in your name either way.
What do enterprise customers ask for, and can you build it?+
Single sign-on through SAML or OIDC, audit logs, role management, session controls, encryption and data export. We build each of them into the platform and help you answer the technical questions on a customer's checklist accurately, so the security conversation speeds the deal up instead of stalling it.
