ELVIS NDAYISHIMIYE / ENGINEERING CONSULTING
Systems architecture and engineering consulting for businesses, institutions and teams building dependable software and data platforms.
I help connect business requirements with data design, software implementation and the realities of operating a system.
For disconnected sources, fragile reporting and pipelines that need clearer ownership.
Python · SQL · PostgreSQL · API integration
For backend services, business workflows and integrations that need reliable implementation.

For new platforms, system evolution and decisions about integration, hosting and operational responsibility.
Business requirements · Data ownership · Reliability · Delivery constraints
For manual deployments, inconsistent environments and teams that need a repeatable delivery process.

Deliverables are selected for each engagement. Existing languages, infrastructure, team capacity and ownership constraints inform the solution.
Work through one defined decision, review options and agree practical next steps.

Review selected architecture, data flows, source code or delivery practices against your objectives.
Output: findings, evidence, priorities and an improvement roadmap within the reviewed scope.
Translate an agreed requirement into architecture, a working component or a delivery improvement.

Software, platform and data engineering experience, with a growing focus on systems architecture and institutional technology decisions.
My work brings together backend development, business workflows, database design, cloud infrastructure and software delivery automation. I work from Burundi and welcome relevant remote engagements across borders.
The architectural direction is deliberate: understand how an organization works, identify what its systems must support, and make technology decisions that teams can implement and sustain.
ISARI is a separate independent research initiative focused on institutional architecture. Commercial consulting is scoped and contracted separately.
Describe your current environment, the decision or problem, your expected outcome and timeline. An initial inquiry helps establish fit; a paid engagement begins only after scope and fees are agreed.
Share a high-level description. Confidential material can be reviewed through an agreed channel after access and confidentiality arrangements are established.
