Hire Full-Stack Developers
Hire Full-Stack Developers Who Own The Whole Build, End To End
Full-stack hiring goes wrong when one person owns the interface and guesses at everything behind it. Stallyons is a Delaware-registered US company. Our engineers average four-plus years across frontend, backend and database work, keep your hours, and sign IP over before anyone gets access.

What Hiring Full-Stack Developers Really Means
A full-stack developer builds both sides of an application: the interface people use and the server, database and API work behind it. Hiring one means a single engineer can carry a feature from a ticket to production without a handoff. That is the value and also the risk, because the title stretches from a genuine generalist to someone who has only ever wired a form to a template somebody else designed.
Stallyons is registered in Delaware as a US company and our engineers are distributed globally, with at least four hours of daily overlap with your working day. You sign a US contract, run diligence on a US entity and pay one US invoice. We have been building software for twelve-plus years, have delivered across six continents and keep around thirty-five engineers on staff, so a full-stack hire arrives with frontend and backend specialists behind it rather than one person alone on an island.
What Full-Stack Work Covers
One engineer, both halves: a developer who owns the API and the interface removes the handoff where most sprint time disappears. Fewer tickets bounce between two people who each believe the other broke the build.
Delivery on your clock: we agree an overlap window before anything starts, so stand-ups, reviews and escalations happen live with your working day rather than landing overnight as a wall of text.
IP protection and security: NDA and IP assignment are signed before a single credential moves, access is scoped per person, and repositories, design files and documentation stay in your accounts.
Cover when someone is out: written scope, named engineers, documented decisions and a briefed second pair of hands, so a holiday, an illness or an exit never becomes your emergency.
Quality control you can inspect: code review on every merge, tests on both halves, an agreed definition of done, and work tracked on your board where you can read it yourself.
One accountable vendor: one contract, one invoice, one entity to run legal and finance diligence on, instead of a frontend contractor and a backend contractor in two jurisdictions.
Why Companies Hire Full-Stack Developers From Stallyons
- Before you hire, ask for one repository the candidate built end to end: interface, API and schema. A full-stack CV that only shows screens is a frontend CV.
- Get the IP wording in writing: assignment of everything produced, no licence-back, no shared ownership, and the NDA executed before any credential moves.
- Ask who you escalate to. You want a named person with authority to change the plan, reachable inside your overlap window, not a shared inbox.
- Test the seam, not the layers. Give a small task that needs a schema change, an API change and a UI change together, and watch how the three are kept in step.
- Check the exit before you need it. Repositories, cloud accounts and design files sit in your own name from day one, so leaving is admin, not a negotiation.
- Insist on a written handover: decisions, open threads and known issues documented as work happens, so whoever picks it up next reads instead of guesses.

Common Challenges
Why Full-Stack Developer Hires Go Wrong
Six failure patterns behind almost every bad full-stack hire. None of them are about where the developer happens to sit.
Broad But Shallow
01
Someone who has touched ten technologies and finished none of them interviews brilliantly. The gaps only surface when a feature needs a decision nobody on the team can second-guess.
The Seam Gets Dropped
02
The bug is never in the interface or in the API. It lives in the contract between them, which is exactly the part nobody wrote down or claimed ownership of.
Half A Full-Stack Dev
03
Plenty of full-stack CVs are a frontend CV with an ORM bolted on. You find that out at the first schema change, not in the interview.
IP Left Unsigned
04
Plenty of engagements start with repository access and no signed IP assignment. You only discover which country's law governs your code once there is a dispute.
Rework Eats The Budget
05
Code that ships without review, tests or an agreed definition of done comes back as bugs. The second pass gets paid for at your own team's rate, on your own team's time.
Nobody Owns The Outcome
06
Split one feature across three contractors and every missed deadline has a plausible owner elsewhere. Accountability needs one name on one contract.
Seen a few of these before? Let's do it properly.

6 Ways To Hire Full-Stack Developers
Six ways to bring full-stack capacity in from one accountable vendor. Run one, or run several in parallel under a single contract.
Full-Stack Product Builds
01
End-to-end delivery of a defined product or module: scope, build, test and release, with a named lead who reports into you and a written plan you approve before work starts.
Embedded Full-Stack
02
A full-stack engineer working alongside your in-house team on your board, your tools and your review rules, without you opening an entity or running a second hiring process.
Rebuilds & Migrations
03
Legacy systems rewritten, migrated or replatformed in stages, with the old system running until the new one has earned the switch.
Full-Stack QA & Testing
04
Standing testing capacity that runs on your release cycle: manual passes, automated suites, regression before every deploy and a written sign-off.
Cloud, DevOps & Support
05
Infrastructure, pipelines, monitoring and release cover, so the engineer who builds the feature is not the only person on earth who can deploy it.
AI, Data & Automation Builds
06
LLM features, internal automation, data pipelines and integrations, built against your own data-handling rules and shipped behind your own review process.
Not sure which full-stack model fits you? Let's scope it together.
Why Choose Us
What Makes Our Full-Stack Developers Different
The details that decide whether a full-stack hire works, rather than the ones that demo well.
A US Legal Entity
01
Stallyons is registered in Delaware. Your contract, your invoice and your legal recourse sit with a US company, not an unknown one.
Both Halves, Proven
02
We do not label a frontend developer full-stack to fill a seat faster. The people we quote are the people who write both halves of the code.
Overlap You Set
03
You choose the hours we share with your working day, and stand-ups, reviews and escalations all happen inside that window.
IP Locked Down First
04
NDA and IP assignment are signed before any repository, credential or design file changes hands. Everything produced on the work is yours.
Merge Reviewed
05
Every merge is reviewed on both halves against an agreed definition of done, on your board, where you can read it.
One Contract
06
One contract covers the engagement, so procurement, legal and finance each deal with a single named counterparty.

"We came to Stallyons after burning two years and four vendors on a multi-platform launch that kept slipping. They scoped it end-to-end — web app, iOS, Android, an AI summarization layer, and a Shopify integration — and shipped it in 22 weeks. One team, one budget, one quality bar. We've handed them three more engagements since."

"Stallyons rebuilt our customer-facing portal, integrated three legacy systems, shipped an AI document analysis pipeline, and brought our compliance posture to SOC 2 — all under one engagement. The senior engineers on the team have shipped at companies five times our size. It's the best vendor decision we've made in a decade."

FAQ
Questions About Hiring Full-Stack Developers
A full-stack developer builds both sides of an application: the interface people use and the server, database and API work sitting behind it. In practice one engineer can carry a feature from a ticket to production without handing it between specialists. Depth varies enormously, so the useful interview question is not whether someone is full-stack, but which half they have shipped and then maintained under real load.
A specialist goes deep on one layer. A full-stack developer works across the whole path, from the component a user clicks to the query that answers it. Specialists win when the problem is hard in one place: heavy data modelling, complicated interface state, awkward infrastructure. Full-stack wins when the work is broad and the team is small, because every handoff between two people costs a conversation and a day. Most teams run a mix of both.
Rates vary by seniority, region and how much management you buy, so a single number quoted before scoping is a guess. What actually decides your cost is how well the work is defined, how senior the engineer is, and how much rework the engagement generates. A cheaper developer who needs a second pass is the expensive option. We price after scoping, itemized.
Start with the roadmap rather than the CV. Write down what has to ship in the next two quarters, then work out which layers that actually touches. Ask candidates for something they built end to end and have them walk you through a schema decision they now regret. Check when IP assignment gets signed, how access is granted and revoked, and agree overlap hours before anyone starts.
You do, from the first commit. NDA and IP assignment are signed before anyone gets repository access, with no licence-back and no shared ownership. Repositories, credentials, design files and documentation live in your own accounts throughout, so nothing has to be handed back at the end because nothing ever left.
Access is scoped per person and granted only for what a role needs, then revoked when it is no longer needed. Work happens in your environments under your data-handling rules, and we follow your policies on where data may be stored and who may see it. Our delivery is HIPAA, SOC 2, GDPR and PCI-DSS-aligned, and sector rules go into the contract.
You set an overlap window before work starts, and stand-ups, reviews and escalations happen inside it, whether you sit in North America, the UK and Europe, the Middle East, Singapore, or Australia and New Zealand. We keep at least four hours of daily overlap with your working day. Work is tracked on your board and you get a named lead, not an inbox.
The common ones are unclear scope, a generalist sold as a senior, no shared working hours, unsigned IP and knowledge disappearing when somebody leaves. We address them the same way each time: written scope, named engineers you meet and approve, an agreed overlap window, IP signed before access, and a documented handover before anyone rolls off.
