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.

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

Both. Architecture Sprints and audits are always fixed scope. Build engagements typically start with a costed roadmap from the Sprint, then run as monthly retainers with named engineers — so capacity is predictable on both sides.

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.

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.

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.

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.

01 · How we start

Every engagement starts with clear scope.

Some projects begin with a 5-day Architecture Sprint. Others with a focused website, portal, MVP or platform build. In every case we define workflows, system logic, responsibilities and the delivery plan before production work 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 signed off before any code.

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 services

Five engineering clusters.

One commercial entry layer. Specialised audits, migrations and narrower formats live below as a second layer.

MVPs, platforms & business apps

Production-ready MVPs, custom platforms, client portals and internal business applications. We design the system, build the core flows and hand it over in a state your team can maintain and extend.

Backend & architecture

Backend systems, APIs, event flows and architecture decisions for products that need reliability proven before scale exposes the cracks.

Websites, portals & lead systems

High-quality websites, landing systems and product interfaces where UX, SEO, CRM, analytics and engineering have to work together. Modern Next.js / React stack, conversion-aware from sprint one.

DevOps & infrastructure

Cloud infrastructure, deployment pipelines, observability and resilience for teams that need delivery and operations to scale together. One engineering discipline, not five vendors.

Integrations, data & practical AI

CRM logic, data pipelines and operational integrations that turn disconnected tools into systems people actually use. AI here is a feature inside your platforms — not a standalone product.

03 · Common scenarios

What teams come to us with.

Each scenario maps to one of the five clusters above — every link stays inside the architecture, no orphans.

Scenario · 01

“We need a serious website that also generates leads”

The current site doesn't convert, doesn't rank, or doesn't connect to the actual sales process.

Scenario · 02

“We need a client portal or internal tool”

Customers, partners or internal teams need a secure, role-based interface — not another shared spreadsheet.

Scenario · 03

“We are replacing spreadsheets and manual operations”

Operations have outgrown Excel, Notion, Airtable and disconnected tools. Errors and lost context are getting expensive.

Scenario · 04

“We're stuck with a fragile MVP”

The product works, but every change breaks something else.

Scenario · 05

“Our system doesn't scale anymore”

Traffic, data, or users grow — reliability doesn't.

Scenario · 06

“We need to pass audits / compliance”

Security, GDPR, data flows and traceability must hold under review.

Scenario · 07

“Our analytics can't be trusted”

Decisions are made on dashboards nobody fully believes.

Scenario · 08

“We're rebuilding too often”

Rewrites slow the roadmap and kill momentum.

04 · Specialised formats

Audits, migrations and focused engagements.

Specific delivery formats for existing systems — when you don't need a full build, but a precise intervention.

01 · Open format

Architecture & DevOps audits

System-level audits with prioritised findings, risk analysis and a costed action plan. For teams considering a build, a rewrite, or fundraising-grade due diligence.

02 · Open format

Platform support & maintenance

Structured ongoing development and SLA-ready operations for complex platforms with multiple stakeholders. Senior engineers, not ticket queues.

03 · Open format

Migrations & relaunch

SEO migrations, platform modernisation and technical relaunches without ranking loss or downtime. Phased delivery while operations stay live.

04 · Open format

Performance optimisation

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

05 · Where we ship

Two primary verticals, five 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.

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.
02
Named senior engineer from day one
You work directly with the engineer designing your system. No account managers, no offshored execution, no “let me check with the team and get back to you”.
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.
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 production work begins on a fuzzy brief.
