Architecture-First Engineering Services

Senior engineers and 5-day Architecture Sprints for funded B2B SaaS startups and Mittelstand teams. Built to survive growth — not to be rewritten.

01 · How we start

Every engagement begins with an Architecture Sprint

Five working days. One senior engineer. A clear map of system boundaries, scaling risks, stack decisions, and a delivery roadmap — before a single line of production code.

5 days
Fixed scope, fixed price
1 senior engineer
Named from day one
Reduced risk
Rewrite risk lowered before the build

02 · Core services

Five engineering clusters

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

03 · Common scenarios

What teams come to us with

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

We’re stuck with a fragile MVP

The product works, but every change breaks something.

Our system doesn’t scale anymore

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

We need to pass audits / compliance

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

Our analytics can’t be trusted

Decisions are made on dashboards nobody fully believes.

We’re rebuilding too often

Rewrites slow the roadmap and kill momentum.

06 · Why H-Studio

What makes the engagement different

01

Built to reduce rewrite risk at seed-stage growth

Most agency MVPs need a rewrite by the time the product hits real traffic. Ours rarely do, because we treat architecture as the first deliverable — not as something the next team will figure out.

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 — not afterthoughts.

04

Architecture defined before first feature

We refuse to start a build before system boundaries, data flows, and scaling risks are mapped. The 5-day Architecture Sprint exists exactly so the next 9 months don't get rebuilt.

07 · FAQ

Questions teams ask before signing

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.

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.

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.

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.

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.

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.
