What Our Developers Build

JavaScript Skills & Expertise

From React and Next.js frontends through Node.js APIs, Vue 3, Angular, TypeScript migration, full-stack MERN/T3 products, performance engineering, real-time features, and code review — our JS developers cover the full spectrum.

01

React & Next.js Application Development

Production React applications — functional components, hooks (useState, useEffect, useCallback, useMemo, useRef, custom hooks), React Context, state management with Zustand or Redux Toolkit, React Query/TanStack Query for server state, Next.js App Router with Server Components and Server Actions, streaming SSR, and incremental static regeneration. Performance optimisation: code splitting, lazy loading, memoisation, bundle analysis.

02

Node.js Backend & REST/GraphQL APIs

Scalable Node.js backends — Express.js or NestJS (with dependency injection, modules, guards, interceptors, decorators), REST API design (versioning, pagination, filtering, OpenAPI spec), GraphQL (Apollo Server or Pothos with Prisma), JWT and OAuth 2.0 authentication, rate limiting, caching with Redis, WebSocket real-time layers with Socket.io or uWebSockets.

03

Vue.js & Nuxt 3 Development

Vue 3 with Composition API — composables, Pinia state management, Vue Router 4, Teleport, Suspense, script setup syntax. Nuxt 3 with auto-imports, server routes (Nitro engine), hybrid rendering (SSR/SSG/SPA), Nuxt Content for content-driven sites, and Nuxt UI or PrimeVue component libraries. Performance-tuned for Core Web Vitals.

04

TypeScript Migration & Architecture

TypeScript adoption and migration — incremental JS-to-TS migration strategy, strict mode configuration, utility types and generics, discriminated unions for type-safe state machines, module augmentation, declaration merging, and monorepo TypeScript configuration with Turborepo or Nx. Code review and architecture guidance for TypeScript codebases.

05

Angular Enterprise Development

Angular (v15+) — standalone components, signals-based reactivity, RxJS (operators: switchMap, concatMap, mergeMap, exhaustMap, BehaviorSubject, combineLatest), NgRx for complex state, Angular Material or PrimeNG UI, lazy-loaded feature modules, guards and resolvers, interceptors for auth/logging, and performance optimisation with OnPush change detection.

06

Full-Stack JavaScript (MERN / MEAN / T3)

End-to-end JavaScript product development — MERN (MongoDB, Express, React, Node), MEAN (with Angular), T3 Stack (Next.js, TypeScript, tRPC, Prisma, Tailwind), or custom full-stack architecture. Database integration: PostgreSQL (with Prisma or Drizzle ORM), MongoDB (Mongoose or native driver), Redis, and Supabase.

How We Hire

Our JavaScript Developer Hiring Process

From requirements to first commit in 3–5 business days — transparent, technical, and no bait-and-switch.

01
Share Your JavaScript Requirements

Tell us what you need — the JavaScript frameworks in your stack, the nature of the work (feature development, bug fixing, architecture, migration), your team size, time zone requirements, and your start date. The more context you give, the better the developer match. A 15-minute call with our technical team helps us understand your stack depth and team dynamics.

02
Shortlisted Developers Within 24 Hours

Within 24 business hours, we send you a shortlist of 2–3 pre-vetted JavaScript developers who match your requirements. Each profile includes their specific JavaScript expertise (frameworks, seniority level, open-source contributions or portfolio), communication style, time zone availability, and sample code or past project descriptions. No generic CVs — these are developers who have already cleared our technical vetting.

03
Technical Interview — Your Questions, Your Bar

You interview the shortlisted developers directly. We encourage you to test them on your specific stack — have them solve a problem relevant to your codebase, ask about edge cases they have encountered, or do a live code review of a snippet from your project. We do not coach developers for your interview. What you see is who they are.

04
Optional Paid Trial (1 Week)

Before committing to a longer engagement, you can run a one-week paid trial with your chosen JavaScript developer — a real task from your backlog. This lets you assess code quality, communication cadence, initiative, and how well they ramp up on your codebase before making an ongoing commitment.

05
Engagement Kick-Off & Onboarding

Once you select a developer, we handle the engagement formalities — NDA, IP assignment, working hours agreement, and communication norms. The developer joins your Slack/Teams, gets access to your repositories, and attends your first sprint planning or team standup. We provide an account manager as a single point of contact for any operational concerns.

06
Ongoing Quality Reviews & Easy Replacement

We conduct monthly check-ins to ensure delivery quality and team satisfaction — not just yours, but the developer's too. If at any point the engagement is not working (performance, communication, changing requirements), we replace the developer within 5 business days, no exit penalty. Your engagement continues without interruption.

Client Results

What Our Clients Say

Engineering managers, CTOs, and agency delivery leads across the US, UK, and Australia on hiring JavaScript developers from 1Solutions.

★★★★★

We hired a dedicated JavaScript developer from 1Solutions to extend our React/Node.js team. He was fully up to speed on our codebase within 3 days and shipping features in week one. Code quality is excellent — he introduced patterns (custom hooks, proper React Query usage, Zod validation) that our own team has since adopted. Highly recommend for React/Node fullstack work.

OH
CTO, B2B SaaS Platform (UK)
★★★★★

We needed a Vue 3 / Nuxt specialist for a client project with a tight 8-week deadline. 1Solutions shortlisted developers within a day, we interviewed two, and our hire started on day 3. She delivered the entire Nuxt 3 frontend — including complex Pinia state and server-side rendering — on time, at quality. The client was happy, and we extended the engagement for phase 2.

PM
Delivery Manager, Digital Agency (AU)
★★★★★

Brought in a JS developer from 1Solutions specifically for a TypeScript migration of our 80K-line React codebase. He produced a clear migration plan, implemented it incrementally without disrupting our normal sprint delivery, and finished in 10 weeks. No regressions, strict mode enabled throughout. Exactly what we needed.

Why 1Solutions

Why Hire JavaScript Developers From 1Solutions

15+ years of JS expertise, full-stack not just frontend, TypeScript-first, communication-first, transparent matching, rapid replacement guarantee, IP ownership, and no vendor lock-in.

15+ Years of JavaScript Expertise

We have been writing JavaScript since before Node.js, React, or Angular existed. Our developers have lived through the JS ecosystem's evolution — from jQuery and Backbone through Angular 1, the React revolution, and the modern full-stack JS era. That history means they understand the why behind architecture decisions, not just the how.

Full-Stack JS, Not Just Frontend

Every JavaScript developer we hire can work across the full stack — React or Vue on the frontend, Node.js on the backend, and PostgreSQL or MongoDB as the data layer. We do not send you frontend-only developers when your role requires full-stack contribution.

TypeScript-First Mindset

TypeScript is not an optional skill for our JavaScript developers — it is a baseline requirement. They work with strict mode, proper generics, utility types, and Zod runtime validation. Your codebase will not accumulate any escape hatches.

Communication-First Hiring

Technical skill without communication creates silos. We screen for English communication fluency, async documentation habits, and the ability to ask clarifying questions rather than make assumptions. Our developers participate in your standups as contributing team members, not silent contractors who only push commits.

Transparent Matching, No Bait-and-Switch

The developer you interview is the developer you get. We do not present a senior developer in the interview and assign a junior for the engagement. The profile, the interview, and the working developer are the same person.

Rapid Replacement Guarantee

If a developer is not meeting expectations — for any reason — we replace them within 5 business days at no additional cost. You are never locked in to a poor match. This guarantee applies for the entire duration of your engagement.

IP Ownership & NDAs From Day One

All code written by 1Solutions JavaScript developers is your intellectual property. Every developer signs an NDA and IP assignment agreement before starting. Source code, documentation, and designs produced during the engagement belong entirely to you.

No Vendor Lock-In

Our developers work in your tools — your Git repositories, your project management, your Slack or Teams, your CI/CD pipelines. When an engagement ends, you take everything with you. No proprietary platforms, no data held hostage.
