Hire a full stack developer who owns the whole feature

Our engineers design the schema, build the API and ship the screen for the same feature, so nothing gets lost in a handoff. You interview them before anyone starts.

What you are getting

4 things that decide this

  1. 01"Full stack" is a seniority claim on this page, not a skills list. Every engineer has taken a feature from data model to shipped UI, alone, on a system now in production.
  2. 02You interview every engineer before they join. Nobody is assigned to your team from a profile you never saw.
  3. 03They embed in your repo and your standups, and stay on the project instead of rotating between clients.
  4. 04If the fit is wrong, say so and we replace the engineer. Every line they write is yours from the first commit.

What a full stack developer actually does here

Most people sold under this title can write frontend and backend code, on different days, handed off between them. A full stack developer owns one feature through every layer and knows which layer is lying when something breaks.

On TrialTriage they built the patient data model and the NestJS API that ranks trial matches. Then they built the React screen a nurse reviews before approving a result, plus the role split between admins, nurses, patients and insurers. On Elevent they built the MySQL schema for live games and the Node and Socket.IO layer that keeps a thousand players in sync. Then they built the Vue interface a host uses to run a session. On Broollie they connected the meeting data model to a GPT-4o-mini agenda step. The screens a team reads minutes from came out of the same hands, across integrations with Zoom, Webex and Twilio.

Three different products, one repeated pattern. The state in the database and the state on the screen belong to one person, so they never drift apart silently.

The work that comes off your roadmap

A schema that fits the feature

They design the data model for where the feature is going, past what today's screen needs. Fewer migrations later.

An API with no guessing at the other end

They write the endpoint and the screen that calls it, so the contract between them matches on day one instead of after a bug report.

State that does not lie to the user

Loading, error and stale-data states are part of the build, not an afterthought bolted on once the happy path works.

A deployment path, beyond code

They ship the feature to a real environment and watch it run, rather than handing a pull request to someone else to release.

How hiring works

  1. 01

    Tell us what is stuck

    A free call about the feature, the deadline and where it currently sits between teams. You will hear honestly if the work needs one engineer or more than one.

  2. 02

    Meet the engineers

    We shortlist people who have owned a feature end to end before, and you interview them. Say no and we go back to the shortlist.

  3. 03

    They embed

    Your repo, your standups, your ticket system. One engineer is named as accountable for the feature, from the schema to the screen.

  4. 04

    They hand over

    Documentation, the data model decisions and a clean deploy path, plus someone on your team walked through both. The first 2 months of support and maintenance are free, with every build.

Tell us what feature keeps stalling between teams

Bring the feature that keeps bouncing between your frontend and backend people. The scoping call is free, and you will leave it knowing what one engineer can own outright.

Questions, answered
01What actually makes someone "full stack" rather than two specialists sharing a title?

Ownership of one feature through every layer, not a resume listing both. Ask for a specific feature they took from data model to shipped screen by themselves, and what broke first when it went live. A candidate who can only describe the frontend half, or the backend half, is one specialist wearing a broader title.

02Do we lose anything by having one person own the whole feature instead of a frontend and backend specialist?

You lose depth in an edge case a narrow specialist might catch faster, and you gain a feature with no handoff gap between the parts. On most product features the handoff gap costs more than the missed edge case. That is why we default to one owner and bring in a specialist only where the work genuinely needs one.

03How much overlap do we get with our working day?

A daily overlap with your hours, fixed before anyone starts. Standups, reviews and pairing happen while both sides are awake, because debugging a feature across layers is a conversation, not a ticket. We agree the window during scoping and it does not move without you.

04Who owns the code once the engagement ends?

All of it, from the first commit. That covers the schema, the API and the frontend. The reasoning behind the decisions gets documented too, so your own team can pick it up without us in the room.

05What drives the cost of hiring a full stack developer through you?

Mostly how much of the stack already exists and how consistent it is. A greenfield feature on a stack you have already chosen is quick to scope. A feature that touches an old, undocumented codebase is the harder case. Scoping calls are free. Where we have to get into an existing codebase before answering, a paid two-week diagnostic produces a fixed price rather than a guess.

Start

Let’s build the one that runs after.

We build AI agents and automation, then stay on under an agreed service level. A senior engineer reads every brief, and your call gets scheduled within 24 hours.

What happens next

  1. 01

    You send a brief or book a call

    Two minutes, whichever you prefer.

  2. 02

    A senior engineer replies within 24 hours

    Not a sales rep.

  3. 03

    Honest scoping, in writing

    And if we’re not the right fit, we say so.

“I started Hashlogics because too many teams ship a demo, get paid, and disappear. We build to a standard we’d run ourselves — and we stay to keep it running.”
