Nile Code

Backend, data & integration engineering for systems that can't afford to be wrong

Nile Code helps B2B companies build and improve backend systems, integrations, data pipelines, cloud services and applied AI — especially where data has to move reliably between products, APIs, databases, financial systems and operational workflows.

  1. Source system

    Reconciled: event_id unique across retries

  2. Transformation

    Reconciled: each source row → exactly one output row

  3. Destination API

    Reconciled: retry reused its idempotency key

  4. Finance

    Exception: totals equal the source

    Rows that differ are listed, each with its reason.

Every record either reconciles at each boundary or appears as an explained exception.

Looking for the education platform? Nile Code LMS is our product for learning centres.

The problems we work on

Each platform in a chain can be working correctly while the data between them is not. That gap is where we work.
  • Backend & distributed systems

    Services that stay correct under load, retries and partial failure.

  • System & API integration

    Data moving between SaaS platforms, internal systems and third-party APIs, without silent loss.

  • Data engineering & integrity

    Pipelines where every record can be traced from where it started to where it landed.

  • Applied AI

    AI inside production systems, with retrieval, validation and human review where they belong.

  • Cloud & production systems

    Infrastructure that deploys cleanly and tells you when something is wrong.

  • All services in detail

    What each one covers, how we work, and the stack.

A focused first engagement: the Billing Pipeline Integrity Sprint

Usage-based billing passes through metering, pricing, a billing platform, invoices and finance. Each system can work while the chain between them loses events, counts them twice, or prices them wrongly.

In seven days we take one boundary in that chain — for example usage events to your billing platform — and build the reconciliation that shows exactly where it disagrees, from read-only data.

How the sprint works

  1. Usage events

    Check: no event missing or counted twice

  2. Billable usage

    Check: every unit attributed to one customer

  3. Billing platform

    Check: invoice lines equal rated usage

One boundary, reconciled end to end.

Built by Nile Code: an education management platform

Our own product, in production for real learning centres: many centres on one platform, nine roles, scheduling, live classes, exams, certificates, fees and bilingual interfaces — the same engineering we bring to client systems.

Ways to work with us

  • Focused engineering sprint

    About 1–2 weeks

    The easiest place to start: one clearly bounded technical problem, a fixed scope, and working output at the end — code, tests and findings you keep.

  • Engineering project

    Several weeks to several months

    A larger backend, integration, data, AI or infrastructure build, planned in milestones and delivered into your repositories.

  • Embedded engineering

    A defined period

    Senior backend engineering working inside your existing engineering or product team, on your tools and your process.

What we build with

Go, PostgreSQL, Redis, REST, gRPC, WebSockets
Infrastructure

Have a system that has to be right?

Tell us where the data moves and where it goes wrong. The first conversation is technical: the systems involved, the boundary that matters, and what a first sprint would produce.
