Web development services

SaaS platforms with authentication, roles, subscriptions and admin tooling; dashboards and data-heavy interfaces; the APIs and integrations that connect a product to payments, CRMs, analytics and the systems a business already runs on; real-time features such as live updates, chat and collaboration; the marketing site that explains the product; and the modernization of software that has aged out of its stack. WeaveLines builds all of them in TypeScript on the React and Node.js ecosystems.

TypeScript and React, with the framework chosen per project: TanStack for application-heavy products where most of the work happens after sign-in, Next.js when it fits, Astro for content-heavy sites. Node.js behind them; PostgreSQL first, with MongoDB, Neo4j or Redis when the data has a different shape; AWS first, Cloudflare where it fits, and a plain server when that is the right size. WeaveLines chooses the stack for each product and builds in the one it will grow in.

By measuring it. The screens and endpoints that matter get performance budgets a release has to meet, and we profile and load-test against them rather than guess. On the back end that means query tuning, caching and pagination designed for ten times the data; on the front end, code splitting and rendering choices made per page. Monitoring after launch tells WeaveLines when a number moves before users notice.

As routine rather than as a phase at the end. Every change is reviewed by a second engineer. Dependencies are kept up to date, secrets stay out of the code, and access to accounts and data follows least privilege. Authentication, authorization and input handling follow OWASP guidance, and staged environments mean nothing is tested in production. WeaveLines builds security into the way the product is made, not into a checklist afterwards.

By starting with the simplest shape that fits the product: a single, well-structured application with clear boundaries inside it, which is what most products are fastest to build and easiest to run in. Separate services or serverless functions come in when load, team size or a specific workload calls for them, and the boundaries drawn early make that split a step rather than a rewrite. WeaveLines writes the decision down as it is made, so the reasoning is there when the product grows.

By assuming the other side will fail sometimes. Calls are retried with backoff, operations are idempotent so a repeated request never duplicates a payment or an order, and every exchange is logged, so a failure is visible and recoverable rather than silent. Webhooks are verified and processed the same way. WeaveLines builds integrations to survive a bad afternoon at the other end.

Yes. WeaveLines sets up and runs the infrastructure the product needs: AWS first, Cloudflare where it fits, or a plain server when that is the right size, with Docker-based deployments, separate development, staging and production environments, CI/CD on every change, and monitoring and error tracking from the first release. When a product outgrows where it started, we migrate it; Rushtera moved between cloud providers with WeaveLines without a gap.

Yes. WeaveLines starts with a short review of the code, the infrastructure and how the product is used, tells you plainly what holds up and what does not, and plans the shortest route to the next release. A rewrite is the last resort, not the first suggestion.

In steps, without stopping the business. We assess what exists, plan the migration around the parts that matter most, move them to a modern stack one at a time, connect the new pieces to the systems that stay, and test after every move. Rushtera came to WeaveLines with a PHP platform that needed re-engineering and left with a modern one, on a new cloud setup.

Work runs in two-week sprints, each ending with a demo of working software. The backlog and the progress are on a shared board you can open at any time, and the WeaveLines team is available to talk, review and decide throughout, not only at the demo. Every change goes through review, automated tests and CI before it reaches staging.

Yes. Design and engineering happen in the same place at WeaveLines: a high-fidelity prototype in days, then the interface and the design system in Figma, built by the same engineers. If you already have a designer or a design system, we build from it.

A scoped web app, dashboard or feature is usually a fixed-price project with an agreed launch date. Ongoing product work runs on time and materials billed monthly, and a retainer covers support, fixes and steady improvement after launch.
