Context

AI agent connected to an internal PDF knowledge base to speed up support and improve answer quality.

Challenge

• Heterogeneous PDF quality (OCR, layouts, noise)
• Need for sourced answers and strict uncertainty handling
• Reduce resolution time without degrading quality

Solution

• Cleaning pipeline + OCR when needed, normalization, and detection of useful sections
• Semantic chunking + citations + confidence threshold
• Automated human fallback and improvement loop via support feedback

Impact

• More consistent answers thanks to internalized documentation
• Estimate: response time for simple requests divided by ~2
• Estimate: level-2 escalations reduced by ~20-40%

Context

Internal portal to publish, track, and distribute desktop app versions (release management).

Challenge

• Reliable publishing flow
• Traceability, rollback, and artifact control

Solution

• CI automation, validation rules, version history, and fast rollback

Impact

• Smoother deployments
• Estimate: distribution errors reduced by ~20-30%
• Better visibility on releases and faster rollback

Context

Scalable event-driven architecture: intake API + RabbitMQ workers to send pushes via Firebase and Apple APNs.

Challenge

• Resilience and backoff
• Fine-grained observability
• Error and traffic spike handling

Solution

• Exponential retry, DLQ, metrics, dashboards, and alerting

Impact

• Horizontal scalability and better incident understanding
• Estimate: +20-30% deliverability during spikes

Context

Desktop client to connect remote readers (WebDAV) and monitor connectivity with automatic recovery.

Challenge

• Mount stability
• UX in network error cases
• Reliable reconnection

Solution

• Reconnection with backoff, explicit states, system notifications, and actionable logs

Impact

• More robust user experience
• Estimate: network incidents reduced by ~30-40%

Context

Production stations with Raspberry Pi + scanner to update order status in real time.

Challenge

• Workshop robustness
• Variable connectivity
• Error tolerance

Solution

• Watchdog, error recovery, local temp queue, and synchronization

Impact

• Real-time traceability
• Estimate: input errors divided by ~2

Context

E-commerce site for creating albums and ordering prints, with secure Stripe payments.

Challenge

• UX flow
• Payment security and webhooks
• Order state management

Solution

• Stripe signature verification, robust order workflow, error monitoring

Impact

• More reliable payments and smoother checkout
• Estimate: order failures reduced by ~15-25%

Context

Secure client portal to consult, analyze, and monitor connected device data.

Challenge

• Data volumes
• UI readability and performance
• Real-time refresh

Solution

• Pagination/virtualization, efficient filters, SSE/WebSocket as needed

Impact

• Faster anomaly reaction
• Estimate: analysis time reduced by ~20-30%
