Senior product engineering across web, mobile, and AI.

Bring Denis in when a digital product needs credible ownership across interface, architecture, delivery, production, and the modern AI workflows that can accelerate each stage.

Web product engineering & modernization

When this helps: A web product needs to move from idea to production, or an existing frontend has become slow, fragile, or difficult to extend.
What Denis does: Clarify product flows, reshape the frontend and integration boundaries, improve accessibility and performance, and establish a maintainable delivery path.
Typical engagement: Focused product build, modernization sprint, architecture review, or hands-on technical leadership.

Applied AI workflow & product prototyping

When this helps: A team wants real leverage from AI but needs more than demos, prompt collections, or unreviewed generated code.
What Denis does: Design a verification-first workflow for research, prototyping, implementation, testing, documentation, and review; build a production-shaped slice to prove it.
Typical engagement: Workflow assessment, enablement sprint, rapid product prototype, or integration into an existing engineering system.

Mobile product delivery & rescue

When this helps: A roadmap is slipping, ownership is fragmented, or a critical release has too many unknowns.
What Denis does: Clarify constraints, map dependencies, reset milestones, take technical escalation ownership, and establish a production-ready delivery model.
Typical engagement: Delivery assessment followed by hands-on interim leadership or a focused recovery program.

Flutter architecture & modernization

When this helps: The app is difficult to change, upgrades keep breaking delivery, or brand/product variants are diverging.
What Denis does: Review boundaries, state management, dependencies, native integration, testing, and migration risk; then sequence modernization around active delivery.
Typical engagement: Architecture review, prioritized plan, and optional implementation leadership.

Native integration & release engineering

When this helps: Signing, stores, SDKs, deep links, notifications, WebViews, or platform channels are blocking a reliable release.
What Denis does: Trace the platform boundary, fix integration and lifecycle issues, strengthen the release path, and document operational ownership.
Typical engagement: Focused technical engagement around a defined integration or release problem.

Mobile CI/CD & production readiness

When this helps: Pipelines are rebuilt per app, releases depend on manual knowledge, or incidents have unclear owners.
What Denis does: Standardize pipelines, signing and environment flow, release gates, checks, observability, and incident follow-up without over-engineering the platform.
Typical engagement: Audit plus implementation sprint, or platform enablement across several teams.

Fractional mobile technical leadership

When this helps: A company needs senior mobile direction before—or instead of—hiring a full-time leader.
What Denis does: Own architecture decisions, technical planning, hiring support, Team Lead coaching, and delivery risk while remaining available for hands-on escalation.
Typical engagement: Part-time recurring mandate with explicit outcomes and decision rights.

Engineering delivery assessment

When this helps: Leadership needs an independent view of why mobile delivery feels unpredictable.
What Denis does: Examine roadmap shape, team interfaces, technical risk, release governance, quality signals, and ownership; return a prioritized, defensible action plan.
Typical engagement: Short diagnostic engagement with interviews, artefact review, and an executive/technical readout.

Advice stays proportional to the product.

An audit is not a pretext for a rewrite. Recommendations distinguish urgent production risk from maintainability work, explain trade-offs, and identify what should remain unchanged.
