Do you only build on AWS, or other cloud providers too?

Our hands-on, repeated production experience is AWS: Zeronest, Centrum Komunikacji, Ticket Club and one more platform under NDA all run there today. We can design cloud-agnostic architectures when a client's constraints call for a different provider, but we do not claim the same production depth on other clouds, and we would say so upfront.

Can you take over an AWS application someone else built?

Yes, and it starts with an audit rather than a rewrite. We map what exists, stabilize what is fragile, then propose changes in that order, the same approach we followed when we took over ongoing AWS work for an existing energy-sector platform.

Are you an AWS partner?

We are working toward the Validated tier of AWS Partner Central. It is a status we are pursuing and have not reached yet.

How do you keep an AWS bill from growing out of control?

Autoscaling tuned to actual load rather than a fixed instance size, plus alerting that flags a cost spike while it is still small. That is the same pair of changes we added to Zeronest's RDS setup: autoscaling first, then alerts that catch what autoscaling alone would miss.

Cloud Application Development on AWS

We build cloud-native applications that live on AWS, provisioned entirely through Terraform. An environment rebuilds itself from code, without a support ticket, and a new region or account starts from the same tested foundation every time.

Cloud Native Application Development, Built the Same Way Every Time

We standardize on AWS: compute on ECS, data in RDS or S3, background work through Lambda, sign-in through Cognito. Every piece is provisioned with Terraform. That standardization is deliberate: one cloud, four production platforms, and the same operational pattern whether we are standing up a new account or maintaining one that has run for two years. You get a scalable, secure environment that reacts to traffic spikes, resists attack attempts, and scales down when traffic drops, so you pay less.

Zeronest's Energy Platform Runs on AWS

Zeronest's solar and battery management platform has been running on AWS since January 2024, now more than two years in production. The containers run on ECS, with RDS and S3 holding the data behind them. Event-driven work goes through Lambda, while Cognito manages user identity, authentication and password resets, so nobody on the team keeps a spreadsheet of credentials. Messaging between services runs through SNS, and every change to that stack deploys through GitHub Actions. Behind it, Python and Django REST Framework run the API, with Celery handling scheduled and background jobs. Terraform provisions all of it, so the setup can be audited and rebuilt from code at any time. The platform now serves several thousand users through three connected applications and covers 16 integrated inverter brands. It runs behind AWS IoT Core, with device traffic encrypted over MQTT and TLS 1.2.

One Repeatable Pattern, Applied to Every Other Account

Centrum Komunikacji (public sector communications), Ticket Club (e-commerce ticketing), and a third platform built for an industrial IoT client under NDA all run on this same Terraform-plus-AWS setup across three different industries. Each environment is defined in code, so a reviewer can read the change before it ships. Every change to the infrastructure carries an author and a timestamp, with the reason attached to the same commit. Terraform state is stored and locked centrally, so two engineers changing the same environment at once get a merge conflict rather than two AWS accounts drifting apart unnoticed. The review step, state lock and audit trail are the same in every client's account, and anyone on the team can open the Terraform files and see exactly what is running.

Working Toward AWS Partner Validation

We are working toward AWS Partner Central's Validated tier, which reviews the Terraform-and-AWS pattern already running in production for the clients above against AWS's own bar for security posture, cost management and operational practice. The review covers infrastructure defined in Terraform, environments that can be rebuilt from code, and a team that has already run this pattern across four production AWS accounts, starting with Zeronest's first environment in January 2024. The validation is currently in progress.

Why Build Your Cloud Application With Us

Infrastructure as Code, Not Console Clicks

Every environment we provision comes from Terraform, down to the security groups and IAM roles, so staging matches production because both are built from the same code. A new environment rebuilds from a single git commit, and a change to one environment is visible in a pull request before it ever reaches the others. That same commit history lets us show, months later, exactly why a setting changed and who approved it. On Zeronest's AWS account, that discipline has held since January 2024, through every environment added since.

One Cloud, Deep Expertise

AWS is the only cloud we build production systems on, across 50+ engagements company-wide - the four Terraform-provisioned platforms above (Zeronest, Centrum Komunikacji, Ticket Club and one more platform under NDA) are our flagship examples, not the full count. Named AWS work beyond those four also includes Enerace's energy platform and KYOTO's thermal-energy-storage digital twin, two separate projects, both public case studies. Clients get engineers who have solved the same class of AWS problem before.

Teams That Stay on the Project

The engineers who provisioned Zeronest's AWS infrastructure in January 2024 still run it today, more than two years later. Long-term ownership avoids the drift that comes from handing infrastructure between different teams every few months, each one relearning what the last one already knew before it can fix anything. It also means the person debugging a production issue at 2 a.m. is the same person who wrote the Terraform module in question.
