The question underneath
What happens when the model is wrong?
The model is one part of the system. Retrieval, evaluation, failure handling, and the human decision around it deserve the same attention.
The work
- Retrieval and document intelligence
- Agentic workflows and model integration
- Evaluation, guardrails, and MLOps
An early decision
Define the acceptable error before choosing the model. Separate confident automation from the decisions that still need a person.
The question underneath
Will the architecture help the product change?
Web, mobile, desktop, and command-line applications. The visible experience and the underlying system are one engineering problem.
The work
- Product architecture and implementation
- Web, mobile, desktop, and API development
- Testing, deployment, and maintainable delivery
An early decision
Keep boundaries aligned with the product's real responsibilities. Add distribution when the constraints justify its cost.
The question underneath
What gives way first under real load?
High-throughput services, distributed infrastructure, and the operational details that determine whether a system keeps its promises.
The work
- High-performance and distributed services
- Streaming pipelines and storage architecture
- Performance analysis and operational hardening
An early decision
Measure the tail, not just the average. Make backpressure, recovery, and data ownership explicit before increasing throughput.
The question underneath
Is the bottleneck the machine, or the idea?
Graph, geometry, numerical, and combinatorial problems. Correctness first, then a careful examination of where the time and memory go.
The work
- Problem modeling and algorithm design
- Performance and memory optimization
- Correctness checks and comparative evaluation
An early decision
State the invariant. Find the counterexample. Choose the simplest algorithm that satisfies the actual constraints.
The question underneath
Which decision will be expensive to undo?
Architecture reviews, technical audits, and fractional CTO work. Clear-eyed judgment that leaves your team with a direction it can execute.
The work
- Architecture and technical-risk reviews
- Fractional CTO and engineering guidance
- Prioritized recommendations and knowledge transfer
An early decision
Distinguish reversible choices from structural commitments. Spend the analysis where being wrong would cost the most.
