Custom software development
Custom software development.
Web applications, APIs, backend and distributed systems, data engineering and pipelines, and cloud on AWS, GCP and Azure. Scoped per project. Price agreed in writing, in US dollars, before work starts.
Web applications
The part people touch, and the part that has to keep working after they do. Web applications built around a real workflow: accounts, permissions, the states a record can be in, and a screen that makes that obvious.
APIs
Interfaces other software can trust. Clear resources, explicit errors, and a way to change the contract without silently breaking a caller.
Backend and distributed systems
Services, workers, and the messages between them. Retries, idempotency, and backpressure are part of the design, not a follow-up ticket.
Data engineering and pipelines
Getting data from where it happens to where someone can use it, without the numbers quietly changing on the way. Kafka and Snowflake are used when they fit the pipeline, not as decoration.
Cloud on AWS, GCP and Azure
Deployment and operation on Amazon Web Services, Google Cloud, and Microsoft Azure. The cloud follows the system, including one you already run.
How an engagement runs
The same rules as the rest of the site. Nothing here is a ranking, a revenue figure, or a guarantee of uptime we have not written into the scope.
- 01
You email us
Tell us what you need, including anything already in production. We confirm scope and price in writing before any work starts.
- 02
You share access
The least access the work needs. We don’t ask for your passwords. We only use material you own or are licensed to use.
- 03
We build, you review
You see the work at agreed points. Where AI tools help with drafting, a person checks what you are asked to approve.
- 04
You approve
Nothing is published or changed in your accounts without your approval.
Tools
Python, Node/TypeScript, Go, PHP, Kafka, Snowflake, AWS, GCP and Azure. AI work adds LangChain, LlamaIndex and MCP, described on the AI page.
