The full handover checklist

Who we are

We build and run our own SaaS product, and we help companies modernize and scale with AI-powered automation, secure systems architecture, and DevSecOps expertise.

In practice that means three overlapping things: backend systems that hold state correctly under load, the pipelines and infrastructure that ship them, and machine learning put into production and kept there. We work in phases, at a fixed price, alongside what you already run — and everything we build ends up in your accounts. The longer version is here.

Work

We don't just advise. We ship.

A product of our own, in production, with real users and a real support inbox. It runs on the same architecture, pipelines, and security practices we set up for clients — so you can go and inspect the work rather than take our word for it.

Workflow automation

Bulk-download Gmail attachments and automate what happens next.

Search years of email in plain language, pull every attachment at once, then auto-save new files to Google Drive, Dropbox, or OneDrive. Web app, Chrome side panel, and mobile.

dioveo.com What building it taught us

What it took to build

  • Durable, long-running jobsPulling eight years of attachments is a job, not a request. Temporal workflows survive a worker dying mid-run and resume where they stopped.
  • Third-party rate limits as an architectureGmail's quotas, not our compute, set the concurrency model. We rewrote the fetch layer twice before accepting that.
  • OAuth under Google security reviewRequesting mail scopes means a review that shapes what you are allowed to build. That belongs before the roadmap, not after it.
  • A year of unhappy pathsHEIC images, corrupt PDFs, expired refresh tokens, revoked access. The demo took a fortnight; the year since has been the edge cases.

Process

Your path to excellence

A simple, effective approach to deliver secure and scalable solutions.

01

Architecture & Strategy

We assess your needs, design modern system architectures, and define the roadmap for scalable success.

02

Build & Integrate

We develop microservices, implement automation pipelines, and integrate secure DevSecOps and MLOps practices.

03

Deploy & Evolve

We launch your solution seamlessly, monitor performance, and continuously improve with reliable, ongoing support.

Services

Innovative services for growth

Tailored solutions to streamline, innovate, and grow.

MLOps Solutions

From data pipelines to deployment, we manage the full ML lifecycle, making AI models production-ready, monitored, and reproducible.

Microservices Development

We build and industrialize microservices that power modern applications, enabling agility, modularity, and faster delivery.

Scalable Cloud Deployments

We design cloud architectures that absorb growth without a rewrite: autoscaling, multi-environment infrastructure as code, and cost you can predict.

DevSecOps & Compliance

Secure CI/CD, infrastructure as code, and continuous monitoring — with the controls and evidence collection that SOC 2, ISO 27001/27002, and Google CASA actually ask for.

Kubernetes & Container Orchestration

We containerize, orchestrate, and optimize workloads with Kubernetes, Docker, and serverless platforms for performance at scale.

Not sure where to start?

Bring us the system that keeps you up at night. We will tell you what we would change, in writing, before you commit to anything.

Security & compliance

Security that survives an audit

Most teams meet compliance as a fire drill three weeks before a customer's security review. We build the controls in from the start, so the evidence already exists when somebody asks for it.

Type I & II readiness

ISO 27001

Control implementation

Google CASA

Restricted-scope assessment

GDPR

EU data residency & DPAs

We implement these frameworks and prepare teams for audit. Certification is issued by an accredited auditor, not by us — we will never tell you a system is certified when what we mean is that it has the controls.

Controls implemented, not just documented

Access review, change management, logging, encryption, and backup controls built into the pipeline so they hold on their own — rather than a policy PDF that describes a system nobody enforces.

Evidence that collects itself

The reason audits hurt is the evidence scramble. We wire collection into CI and your cloud accounts, so the artifacts an auditor asks for already exist and are timestamped.

Third-party security assessments

We have taken our own product through Google's CASA assessment for restricted Gmail scopes. We know what the questionnaires ask, what evidence satisfies them, and how long the review actually takes.

Supply chain and runtime

SAST and dependency scanning in the pipeline, signed images, admission policy on the cluster, secrets in a managed store, and least-privilege service accounts that are reviewed rather than assumed.

What a Google CASA assessment actually asks for

Values

Transparency is the one we build everything else on

Every agency claims it, so here is the specific version — what we show, what we say out loud, and what it costs us. You can hold us to each of these.

Transparency, before anything else

You get the same repositories, CI runs, dashboards, and alert channel we do. No client-facing summary of a summary. When something breaks you hear it from us first, with what happened and what we are changing.

Prices you can check

A fixed price per phase, not an hourly rate against open-ended scope — that model pays us to be slow. Where we resell infrastructure or licences you see the actual invoice, unmarked up.

We tell you not to hire us

If your traffic does not justify the migration you came for, we say so, and that sentence costs us the engagement. We would rather lose a project than build something you resent paying for.

We hand over the keys

Repos, pipelines, runbooks, and credentials are yours from day one. The test we hold ourselves to: if OpsaFlow vanished overnight, could your team keep it running? Until that is yes, we are not finished.

FAQs

We're here to help

Still stuck on something? Ask us directly — we answer every message ourselves.

Systems architecture, microservices development, DevSecOps enablement, MLOps, and Kubernetes and container orchestration. In practice that means we design the architecture, build the services and pipelines, secure them, and run them with you until your own team is comfortable owning it.
