Services · Capabilities

Your on-demand
enterprise IT department.

Senior-level maintenance, development, and auditing on a fractional basis — the expertise of a CTO and the output of a senior squad, without worrying about the complexity beneath it.
Why fractional

Overpay for full-time, or
under-deliver with cheap outsourcing.

Most teams are stuck between two bad options. We built KeenDigit to remove the trade-off.

The problem

Expensive heads, or risky shortcuts

Hiring full-time senior IT staff is expensive — often $100k+/year per head. Cheap outsourcing creates more problems than it solves: bad code, communication gaps, and security risks. You are stuck between overpaying and under-delivering.

$100k+ / year per senior hire
The solution

Senior delivery, fractional cost

KeenDigit provides senior-level maintenance, development, and auditing on a fractional basis. You get the expertise of a CTO and the output of a senior squad, for a fraction of the cost of a full-time hire — with visible controls at every step.

What we deliver

Seven services, ordered by the
stack they keep reliable.

Each service maps to a layer of the stack we own end-to-end — the AI-native product at the top, its substrate beneath, and the infrastructure and assurance that hold it all up.

Layer 01 · Product

AI-Native App Development for Enterprise

Build AI-native applications from requirement mapping to controlled rollout. We design grounding, evaluation thresholds, guardrails, and human review so LLM-powered features can move into production with clear operating boundaries.

Layer 01 · Product

Workflow AI Integration

Embed LLMs into existing workflows to automate checks, drafting, and classification. We add guardrails, human review, and audit trails so AI boosts accuracy and speed without losing accountability.

Layer 01 · Product
Layer 02 · Substrate

API Integration

Connect your systems to external APIs without brittle glue code. We design secure auth, data mapping, and reliable sync so remote data becomes usable inside your business.

Layer 02 · Substrate

Database Optimization

Protect your most valuable asset: your data. We optimize MySQL/PostgreSQL queries, configurations, and backup strategies so the data layer AI depends on stays fast and dependable.

Layer 02 · Substrate

Web Refactoring

Turn your legacy code into a modern asset. We refactor old PHP/JS codebases to modern standards (Symfony, Vue 3) without breaking business logic.

Layer 02 · Substrate
Layer 03 · Bedrock

Server Maintenance

Sleep soundly while we patch your kernels. We handle upgrades, security patches, and performance tuning for Linux servers — the foundation the whole stack runs on.

Layer 03 · Bedrock

Security Audit

Don't trust blindly — verify your vendors. We audit your infrastructure and code for vulnerabilities and backdoors, independently and without conflict of interest.
