Services · Kweezi Perez ChristopherAI Engineering
I build practical AI systems where models, software, data, and product requirements have to work together.
Based in Kampala, Uganda; available for remote collaboration with clients internationally.
01What I build
- AI-enabled web applications and workflows
- Computer vision and image-processing systems
- AI agents and automation workflows
- Model-assisted search, classification, extraction, and decision support
- Production integrations around existing AI APIs and models
02Engineering focus
- Reliable inputs, outputs, validation, and fallbacks
- Clear boundaries between models and business logic
- Evaluation and monitoring instead of treating model output as magic
- Cost, latency, privacy, and deployment constraints
- Human review where automated decisions need oversight
Build AI around a real workflow—not around the model
An AI feature is useful only when it improves a defined task and behaves acceptably when the model is uncertain, unavailable, slow, or wrong. The engineering starts with the workflow, the data it can legitimately use, the cost of an incorrect result, and how a person will review or act on the output.
Use-case and model selection
Identify whether the task needs generation, retrieval, classification, extraction, computer vision, or ordinary deterministic software. Compare hosted APIs and deployable models against accuracy, privacy, latency, cost, and maintenance constraints.
Evaluation and safeguards
Define representative test cases, expected outputs, refusal and fallback behaviour, input validation, access controls, and human-review points. Do not treat fluent output as proof of correctness.
Integration and operations
Connect the model to application data and user workflows with bounded permissions, logging, monitoring, rate limits, and cost controls. Keep critical business rules outside the model where they can be tested directly.
Possible deliverables
- A working AI-enabled feature integrated into an application or internal process.
- Documented model, prompt, retrieval, and data-flow decisions.
- Evaluation cases and checks for quality, regressions, and unsafe outputs.
- Fallback paths, human oversight, access controls, and operational monitoring.
- Deployment and cost guidance based on the selected model and workload.
When should AI be used?
AI is a poor fit when a simple rule or search query solves the problem more reliably and cheaply. It is worth evaluating when language, images, ambiguous information, or large volumes of unstructured data make conventional automation impractical. The first step is to test the use case against representative examples before committing to a production design.
Can AI decisions be fully automated? That depends on the consequence of an error and the evidence from evaluation. Sensitive or high-impact decisions should retain appropriate human review and accountability.

Work with me
If you have a product, workflow, system, or technical problem that needs to become real software, start with the requirements and constraints. I can help turn them into an implementation plan and a production-focused build.
