Architecture-first
engineering services

Senior engineering for MVPs, custom platforms, AI automation, B2B website redesigns and software takeovers — for teams that need systems they can run, own and extend under control.

01 · How we start

Every engagement starts with clear scope.

Some projects begin with a 5-day Architecture Sprint. Others start directly with a focused website, portal, MVP or platform build. In every case, we define workflows, system logic, responsibilities and the delivery plan before implementation starts.

01 · Phase
Workflows & data mapped
We document workflows, roles, data and integrations with you.
02 · Phase
Scope & delivery plan
Scope, system logic and the delivery plan are agreed before implementation starts.
03 · Phase
Production build
Implementation with hosting, monitoring and analytics from day one.
04 · Phase
Handover
Hand-off including documentation — your team can own and extend it.
02 · Core offer

Six clear entry points.

Start with the outcome you need. Blue links mark the primary entry point; lighter links lead to the engineering capabilities that support it.

03 · Common scenarios

What teams come to us with.

Each scenario maps to one of the six entry points above and from there into the right technical scope.

04 · Supporting capabilities

Technical depth behind the six offers.

These pages remain discoverable for clearly bounded work. They are not additional top-level offers; they are the engineering disciplines used within one of the six entry points.

01 · View capability

Platform support & maintenance

Structured ongoing development and operational support for live platforms with real users and multiple stakeholders. Senior engineers, not ticket queues.

02 · View capability

Backend development

Backend systems, data models and architecture decisions for products whose foundations need to grow with traffic, integrations and the team.

03 · View capability

API development

Clear API contracts, versioning, secure access and documentation — for internal, partner and public APIs your next senior hire can actually build on.

04 · View capability

Frontend development

Next.js / React / TypeScript frontends for SaaS, dashboards, portals and internal tools — built around workflows and maintainability, not the launch screenshot.

05 · View capability

DevOps & cloud engineering

Cloud infrastructure, deployment pipelines, observability and resilience as part of a maintainable product, not a separate vendor chain.

06 · View capability

React performance optimisation

React performance, Core Web Vitals and system-level scalability work. Backed by measurement, not vibes.

07 · View capability

SEO migration & relaunch

URL mapping, redirects, metadata and indexing review for controlled technical relaunches where existing visibility needs to be protected.

08 · View capability

Agent-ready architecture

System boundaries, interfaces and data access prepared so AI agents can interact with real product and operational workflows under control.

09 · View capability

AI evals, observability & guardrails

The reliability layer for AI in production — evals, observability, guardrails and cost monitoring. Quality you can watch, regressions caught early. Ongoing via partnership.

05 · Where we ship

Two primary verticals, three platform domains.

We ship most projects across two main verticals. Three additional platform domains and the full industry detail live on the Industries page.

06 · Why H-Studio

What makes the engagement different.

  1. 01

    Built to reduce rewrite risk

    We define workflows, data, permissions and system boundaries before development starts, so the first version can grow instead of becoming a throwaway build.

  2. 02

    Named senior engineer from day one

    You work directly with the engineer designing your system. No opaque hand-offs, no outsourced execution, no account-management layer between you and the technical work.

  3. 03

    Code written to be handed over

    Every engagement is built on the assumption your in-house team takes ownership eventually. Documentation, structure and naming are part of the deliverable.

  4. 04

    Scope agreed before the build starts

    Workflows, integrations and responsibilities are mapped first — sometimes through a 5-day Architecture Sprint, sometimes inside a focused build kickoff. No implementation begins on a fuzzy brief.

FAQ · 06
  1. 01

    What is an Architecture Sprint and what do I get?

    Five working days with a senior engineer. You leave with a system map, scaling-risk model, stack and infra decisions, and a costed delivery roadmap. Fixed scope, fixed price, no commitment to continue.

  2. 02

    Do you take on fixed-scope projects or T&M engagements?

    Both. Architecture Sprints and standalone audits have a fixed scope and price, but they are not a mandatory entry. Understandable projects can move from the free initial assessment directly into a focused fixed-price phase, T&M task or monthly engagement with named engineers.

  3. 03

    Who actually does the work?

    Senior engineers, named from day one and stable across the engagement. We do not subcontract delivery to junior offshored teams. The engineer who designs your system is the one writing the code or owning the team that does.

  4. 04

    Can you join an existing engineering team or only do greenfield?

    Both. We frequently embed alongside in-house teams — leading architecture, owning specific subsystems, or running a contained workstream like a migration or a performance pass — without taking the whole product over.

  5. 05

    What if I just need an audit, not a build?

    Standalone Architecture & DevOps Audits are one of our most common engagements. Two to three weeks, written report, exec readout, and a prioritised action plan. Often used before fundraising or a build vs rewrite decision.

  6. 06

    How do you handle handover so we are not locked in?

    Handover is treated as a deliverable, not a courtesy. Documentation, architecture diagrams, runbooks, and onboarding sessions are part of every engagement. We assume your team takes ownership eventually — that assumption shapes how the code is written.
