Get 3 vetted full-stack engineers - MERN, Next.js, Django, or any stack - shortlisted in 72 hours. One hire who ships your entire product, front to back.
Hiring a full-stack engineer is not the same as hiring a frontend and a backend developer separately - it requires someone who can own the API contract, the database schema, the authentication model, and the deployment pipeline as a coherent system. Our screening covers both layers simultaneously: database query performance, API design (REST or GraphQL), session and token architecture, and frontend rendering strategy. Engineers who are strong on one side but treat the other as someone else's concern do not pass our cross-stack architecture assessment.
Trusted by fast-moving teams
Upwork bids are a lottery. Toptal takes weeks and costs a fortune. We fix both - with AI matching and a flat transparent fee.
You're building a product, not running a recruitment process. Post your brief, get 3 vetted engineers shortlisted in 72 hours. No calls with recruiters, no proposal reviews.
Upwork charges 5-10% client fee plus 5-20% freelancer fee, and your inbox fills with 40 proposals. We charge a flat transparent 15% and send you 3 pre-vetted engineers. That's it.

Don't see your exact use case? Post your brief and we will match you with the right specialist.
Not sure which stack to use? We match you to the right engineer for your product goals - not just your technology wish list.
MongoDB · Express · React · Node.js
JavaScript end-to-end. Fast to prototype, JSON-native data layer, huge ecosystem. Ideal when you want one language across the whole stack and fast iteration cycles.
MongoDB · Express · Angular · Node.js
Angular's opinionated structure suits enterprise teams needing strict conventions, TypeScript throughout, and long-term maintainability over speed of iteration.
Next.js · TypeScript · Node.js · PostgreSQL
Server-side rendering and static generation built-in. Type-safe throughout. The go-to stack for SEO-dependent products, content platforms, and modern B2B SaaS.
Python · Django · React · PostgreSQL
Django's batteries-included ORM, admin panel, and security defaults accelerate data-heavy builds. React decouples the frontend. Best when Python's data ecosystem matters.
Ruby on Rails · React · PostgreSQL
Rails remains unmatched for MVP delivery speed. Convention over configuration means less boilerplate. Proven at scale at GitHub, Shopify, and Airbnb's early stages.
Vue 3 · Nuxt · Node.js · MySQL
Vue's gentler learning curve and Nuxt's SSR capabilities make this stack ideal for teams migrating legacy apps or building progressive web apps with minimal complexity.
Using a less common stack? We also cover TypeScript + NestJS, FastAPI + React, Laravel + Vue, Remix, SvelteKit, and more.
Post your brief and we will tell you within 24 hours if we have engineers for your exact stack.

This is the most common hiring mistake early-stage teams make. Here is an honest breakdown of when each approach wins.
React is the most CV-padded skill in tech. Use these questions to separate engineers who own full delivery from those who only touch one layer.
Walk me through a time you owned a full product build solo - what did you ship, and what would you do differently?
Why it works
Reveals real delivery experience versus team-supported feature work. Watch for: specific product names, concrete user numbers, honest retrospectives. Red flag: vague 'we built' answers.
How do you decide when to use server-side rendering versus client-side rendering?
Why it works
Tests architectural judgement, not just syntax. A strong full-stack engineer explains SEO, TTFB, data freshness, and team capability tradeoffs - not just 'Next.js does SSR'.
Describe your database schema design process. How do you handle schema migrations in production?
Why it works
Full-stack engineers own the data layer. Look for: normalisation decisions, index strategy, zero-downtime migration patterns. Red flag: 'I just use the ORM' with no deeper reasoning.
How do you handle authentication and authorisation in a multi-tenant SaaS application?
Why it works
Security fundamentals distinguish senior from mid-level. Expect: JWT vs session tradeoffs, refresh token rotation, row-level security, RBAC vs ABAC. Red flag: cookie-cutting boilerplate without understanding.
Your API response times have degraded by 3× over 6 months as data grew. How do you diagnose and fix this?
Why it works
Performance debugging is essential for full-stack ownership. Look for: slow query logs, N+1 detection, caching strategy, DB index analysis. Red flag: 'just add more servers'.
How do you structure your frontend state management? When do you reach for global state versus local?
Why it works
State management complexity is where full-stack engineers often show gaps. Expect thoughtful discussion of Context API vs Zustand vs Redux, server state (React Query), and avoiding unnecessary abstraction.
Only claims full-stack but can't explain the database layer
Ask about indexing, joins, or query optimisation. If answers are vague, they are a frontend engineer who has touched Node.js.
No shipped product they can point to
Full-stack engineers should have URLs, GitHub repos, or named clients. 'I worked on internal tools' without specifics is a warning sign.
Jumps to frameworks without justifying why
Senior engineers choose tools for reasons. 'I used React because everyone uses React' versus 'I chose Next.js because we needed SSR for SEO' signals very different levels.
Cannot explain their CI/CD pipeline
Owning a full product means owning deployment. If they have never set up a pipeline from scratch, they have not really owned end-to-end delivery.
Claims to know 8+ frameworks at expert level
A realistic senior full-stack engineer is expert in 1-2 stacks, proficient in 2-3 more, and honest about gaps. CV padding is endemic in full-stack job postings.

Everything founders and hiring managers ask us before their first engagement.
A full-stack developer owns the entire web product: the frontend (what users see), the backend (APIs and business logic), and the database (how data is stored and queried). They can build and deploy a complete application independently without needing separate frontend and backend specialists. This makes them particularly valuable for startups and small teams where one engineer needs to ship a complete product.
Every full-stack engineer passes a multi-stage admission process: CV and portfolio review, a live coding screen covering both frontend (React/Vue) and backend (Node/Django/Rails) simultaneously, a system design interview assessing database schema and API architecture decisions, and a management evaluation. React is the most CV-padded skill in tech - our live coding screen is non-negotiable and cannot be bypassed. The live full-stack screen tests both layers simultaneously - engineers must design an end-to-end data flow from database schema to API contract to UI state, explaining where each piece of data lives and how it is invalidated. Auth and session architecture is assessed: engineers must implement JWT refresh token rotation or session-based auth with CSRF protection and explain the security implications of each approach. WebSocket versus polling is compared for a given real-time use case, and monorepo tooling decisions (Turborepo, Nx, or a flat structure) are assessed against the client's stated team size and deployment model.
You receive 3 shortlisted, pre-vetted full-stack engineers within 72 business hours of submitting your brief. Our AI scans 480+ engineers and a senior engineer validates each match manually against your stack, seniority requirement, and timezone.
Our core stacks are MERN (MongoDB, Express, React, Node.js), MEAN (MongoDB, Express, Angular, Node.js), Next.js + Node.js, Django + React, Rails + React, and Vue + Node.js (Nuxt). We also cover TypeScript + NestJS, FastAPI + React, Laravel + Vue, Remix, SvelteKit, and more. Post your brief and we will confirm stack availability within 24 hours.
Developer rates range from $20 to $160 per hour depending on seniority and region. Open IT Freelancers adds a flat 15% management fee on top of the developer rate. There is no matching fee - you pay $0 to receive your shortlist. Our fee covers vetting, managed delivery (weekly reports, milestone tracking), and the 14-day replacement guarantee.
Yes - and this is how most of our clients work. A strong senior or mid-level full-stack engineer can own the entire product: database schema, API design, frontend build, and cloud deployment. Many of our clients go from brief to deployed MVP in under 90 days with a single engineer. For complex products requiring multiple parallel workstreams, we can match multiple engineers.
If within the first 14 days the engineer is not the right fit, we replace them at no extra cost. No arguments, no delays - we activate the replacement process within 24 hours. After 14 days, engagements run on 14-day notice with no penalties.
You own 100% of all code, database schemas, infrastructure configuration, and documentation. Ownership transfers automatically to your company on work approval through our tri-party contract signed on day one. There are no licensing restrictions, no platform lock-in, and no IP held by the engineer or by Open IT Freelancers.
No long-term contract. No lock-in. Engagements can run for as short as 4 weeks (for an MVP sprint) or as long as 24+ months (ongoing product development). The only commitment is a 14-day notice period to end an engagement, with zero early termination penalties.
When you post on Upwork, you receive 40-200 proposals within hours - mostly from engineers who mass-apply without reading your brief. You then spend days reviewing, shortlisting, and interviewing. We invert this: you post your brief once, we do the screening, and you receive exactly 3 vetted engineers who match your stack and seniority requirement. We also add a flat transparent 15% fee versus Upwork's combined 10-30% across client and freelancer.
Yes. Most of our engagements involve inheriting an existing codebase - whether a legacy PHP monolith, a partially-built React app, or a Django project that needs scaling. Our engineers are screened for code review capability and codebase navigation, not just greenfield builds.
You can - but a full-stack engineer hired for only one layer is often a poor fit. If you only need frontend or backend work, we recommend hiring a React specialist or a Node/Django backend specialist instead, as they will be deeper in that domain. Post your brief and our matching team will recommend the right role for your actual work scope.
