Hire a SaaS Developer
Bracket Coder builds and ships multi-tenant SaaS products. When you hire a SaaS developer from our team, you get a senior engineer who has already wired up tenant isolation, subscription billing, role-based access, and admin dashboards for real applications — not a starter template you have to finish yourself. We work primarily in Django and Python on the backend and Next.js and React on the front end, with Flutter when you need native mobile, so one team can own your API, your web app, and your billing logic end to end.
Most founders reach us with a working idea and a proof of concept that will not survive its first paying customers. The hard parts of SaaS are rarely the features on the marketing page. They are keeping one tenant's data from leaking into another's, handling failed card charges and plan changes without losing revenue, and making sure the dashboard still loads when a customer imports a hundred thousand rows. We build those foundations deliberately so the product holds up as you add seats, tiers, and integrations.
Multi-tenant architecture and authentication
Tenancy is the first decision that is expensive to change later, so we make it on purpose. Depending on your data-isolation needs and compliance posture, we implement shared-schema tenancy with a tenant key enforced at the query layer, schema-per-tenant, or separate databases for customers who require hard isolation. Row-level checks and scoped querysets keep each account's data private, and we test those boundaries rather than assume them. On authentication, we set up email and password with verified sign-up, social login, magic links, or SSO and SAML for enterprise buyers, plus two-factor where it matters. Sessions, token refresh, password reset, and invite flows are handled properly so support tickets do not pile up in your first week live.
Billing, subscriptions, and roles
We integrate Stripe and other gateways to handle plans, trials, proration, metered or seat-based pricing, coupons, and upgrades or downgrades mid-cycle. Just as important, we handle what happens when billing fails: dunning for declined cards, webhook processing that stays in sync with your database, invoices and receipts, and clean cancellation and refund paths. Our team has shipped real gateway refunds and dispute webhooks, so revenue edge cases are familiar ground rather than a surprise late in the build. Roles and permissions are built to match how your customers actually work: organization owners, admins, members, and billing contacts, with granular permissions when a plan needs them. We keep the permission model readable so you can add roles later without unpicking the whole system.
Dashboards, APIs, and scaling
The product your users log into is where the work shows. We build responsive dashboards in Next.js and React with the tables, filters, search, charts, and settings screens a SaaS needs, plus admin tooling for your own team to manage accounts, run server-side search, and handle support. Real-time features like presence, notifications, and live progress use WebSockets where they genuinely add value. For integrations and mobile clients, we design clean REST or WebSocket APIs with versioning, rate limiting, and documentation. As you grow, we handle the scaling work that keeps it fast: query optimization and indexing, caching, background jobs and queues for heavy tasks, access-controlled file storage and downloads, and sensible logging and monitoring so you see problems before your customers do.
How hiring a SaaS developer works
You can hire us to build a new SaaS from scratch, take over an existing codebase, or add a specific capability such as billing or a new tenant model. We start with a short scoping conversation to understand your product, users, and constraints, then propose a plan with realistic milestones and a range rather than a fake fixed number. You work directly with the engineers writing the code, led by Sharan Sifat, and you own the source and infrastructure throughout. Engagements can be a fixed-scope project or ongoing development as your roadmap grows. Whichever fits, we favor small, reviewable releases over big-bang launches, so you can put the product in front of customers early and adjust as you learn.

Frequently asked questions
How much does it cost to hire a SaaS developer?+
It depends on scope. A focused addition like Stripe billing or a new auth flow is a small engagement; a full multi-tenant product is larger. After a short scoping call we give a realistic range and milestones rather than a fixed number that ignores the details of your product.
Which tech stack do you use?+
Primarily Django and Python on the backend with Next.js and React on the front end, and Flutter for native mobile. We integrate Stripe for billing and use WebSockets for real-time features. If you already have a stack in place, we can work within it.
Can you work on our existing SaaS instead of building from scratch?+
Yes. We take over existing codebases, fix or refactor tenancy and billing, add features, and improve performance. We start by reading your code and mapping the risky areas before changing anything.
How do you keep tenant data isolated and secure?+
We choose a tenancy model — shared schema, schema-per-tenant, or separate databases — based on your isolation and compliance needs, enforce access at the query layer, and test those boundaries. We also handle auth, roles, and secure file access rather than bolting security on at the end.
Who actually does the work?+
Senior engineers at Bracket Coder, led by Sharan Sifat. You work directly with the people writing your code, and you own the source and infrastructure throughout the engagement.
