Full-Stack Web Development Services

What is full-stack web development?

Full-stack web development is the design, build, and operation of a web application as one system: the browser interface, the server-side API, the database, and the deployment pipeline. Techroniqs builds these on React, Next.js, TypeScript, Node.js, NestJS, Ruby on Rails, and PostgreSQL. Across 16 production engagements this has included GreenPal, a US lawn-care marketplace serving more than 500,000 homeowners, and the Cresta.ai enterprise interface, which was held to a 99%+ uptime requirement.

Key takeaways

• Full-stack means one team owns the interface, the API, the data model, and the deploy pipeline — no hand-off gaps between vendors.
• Our default stack is React and Next.js on the front, Node.js/NestJS or Ruby on Rails on the back, and PostgreSQL for data.
• Rendering strategy is a per-route decision, not a per-project one. Marketing routes are statically generated; dashboards render on the client behind auth.
• Engagements start at $2,000 for a fixed-scope build, or $20–$35/hour on time and material.
• We have taken web platforms from first commit to production at 500,000-user scale, and inherited existing codebases mid-flight.

• Founders who need a first production version that will not have to be thrown away at Series A.
• Teams with an existing app that has outgrown its original architecture.
• Companies whose in-house team is strong on one side of the stack and needs the other side covered.

Every engagement produces these. Anything else is scoped explicitly rather than assumed.

Architecture and data model

Schema design, API contract, and the reasoning written down before code is written.

Production web application

Responsive interface, server-side API, and database, deployed and running.

Authentication and permissions

Session handling and role-based access — Clerk, OAuth, or a custom layer depending on the requirement.

CI/CD pipeline

Automated build, preview environments per branch, and one-command production deploys.

Source code and ownership

The repository is yours from the first commit, with commit history intact.

Handover documentation

Runbook, environment setup, and architecture notes so another team can pick it up.

Next.js can render the same application four different ways. Picking per route rather than per project is the single highest-leverage performance decision in a modern web build.

This site uses static generation for every public route and client rendering only inside the contact form.

• Decide the data model before the first screen. Retrofitting a schema after the UI exists is the most expensive rework in web development.
• Put the API contract in writing early so frontend and backend can proceed in parallel — this is how the BankBarn engagement stayed unblocked across two teams.
• Render public routes on the server or at build time. A crawler that receives an empty div indexes nothing.
• Set a performance budget in the first week and enforce it in CI, rather than optimising after launch.
• Keep environment configuration out of the repository and in the platform.

Ranges reflect engagements we have delivered. Scope, integration count, and decision speed on your side move these more than anything else.

1. 1. Discovery and architecture

   1–2 weeks

   Data model, API contract, and a scoped build plan.

2. 2. First working slice

   2–4 weeks

   One complete flow running end to end in a preview environment.

3. 3. Build to launch

   6–16 weeks

   Feature-complete application in production. Range depends on scope.

4. 4. Operate and iterate

   Ongoing

   Monitoring, fixes, and new features on a monthly cadence.

Stated plainly, because finding this out in month three costs you far more than reading it now.

• A bespoke web application is the wrong tool for a brochure site. If the requirement is five pages of content, a CMS or site builder costs less and ships sooner.
• We do not take on projects where the scope is a pixel-for-pixel copy of an existing product with no defined differentiator.
• Very large migrations of legacy .NET or Java monoliths sit outside the stack we work in day to day.

What to consider instead

Site builder (Webflow, Framer)

Content-only marketing sites with no custom logic or user accounts.

In-house hire

You need permanent capacity and can wait 3–6 months to recruit and onboard.

Techroniqs dedicated team

You need senior capacity now and want it embedded in your own process.
