Frontend Systems & Product Delivery
Build responsive, data-intensive products with React, TypeScript, GraphQL, accessible UI, testing, and production-minded architecture.
FOUNDER-LED ENGINEERING CONSULTANCY
AI-powered product engineering for complex teams
3D Pros combines senior frontend systems, practical AI workflows, and full-stack delivery for products where performance, accessibility, and reliability matter.
Senior delivery stays hands-on. Your team keeps ownership of the code, assets, documentation, and infrastructure.
DELIVERY PRINCIPLES
Senior ownership from context to production
Every engagement connects business context, architecture, implementation, review, and handover—without separating speed from engineering judgment.
Hands-on Senior Delivery
Architecture decisions and implementation stay close together, with founder-level accountability throughout the engagement.
Visible Scope & Tradeoffs
Milestones, constraints, dependencies, and acceptance criteria are made explicit before they turn into delivery risk.
Evidence Every Cycle
Working increments, tests, reviews, and demos keep progress observable and decisions grounded in the actual product.
Clean Handover
Code, assets, operational notes, and infrastructure remain portable so your team can own what was built.
THE EXPERIENCE BEHIND 3D PROS
Founder-led consultancy. Team-scale impact.
- Client delivery spans Capco financial products, Profeko municipal platforms, and Hemmersbach internal systems.
- React and TypeScript depth covers real-time data, accessible interfaces, complex workflows, and frontend architecture.
- Repository-aware MCP tooling and role-specific AI agents strengthen engineering and QA workflows.
- Documentation, code quality, mentoring, and handover are part of delivery—not work deferred until the end.

These 3D Pros engagements reflect Alfonso Jimenez's delivery path across financial services, public-sector software, and enterprise operations. Confidential product details remain generalized.
3D Pros supports Capco on a financial trading platform combining live market data, specialist workflows, and operationally important code quality.
- Challenge: Fast-changing data, complex interface states, and ambiguity across frontend, backend, and QA made consistent delivery harder.
- 3D Pros approach: Senior React and TypeScript delivery, GraphQL and Apollo integration, rendering optimization, SonarQube-led refactoring, and repository-aware MCP agents for engineering and QA.
- Outcome: Clearer refinements, more consistent reviews, less avoidable rework, and stronger collaboration across engineering and quality workflows.

3D Pros partnered with Profeko on financial modeling and citizen-facing applications for Polish gminas, connecting complex workflows with secure government services.
- Challenge: The interfaces needed to remain usable while meeting accessibility, authentication, legal, and public-sector delivery requirements.
- 3D Pros approach: React, TypeScript, Vite, and Ag-Grid interfaces integrated with C# APIs and gov.pl authentication, supported by WCAG practices and GitHub Actions releases.
- Outcome: Production platforms with verified-citizen login, reusable financial interfaces, inclusive access, and a more structured release lifecycle.

3D Pros supported Hemmersbach as distributed teams depended on heavily used internal React applications handling more than 150,000 production requests each day.
- Challenge: Legacy workflows needed to become faster and easier to evolve without compromising stability or stakeholder confidence.
- 3D Pros approach: React, Redux Toolkit, and TypeScript delivery backed by automated tests, CI/CD, Figma prototypes, code review, and hands-on team enablement.
- Outcome: 150k+ daily requests supported, approximately 30% workflow-efficiency improvement, six or more validated prototypes, and three or more engineers onboarded or mentored.

ENGAGEMENT OPTIONS
Ways to Work Together
Fixed-scope Sprint
Best for clear deliverables and short timelines. A defined scope, plan, and acceptance criteria.
Monthly Delivery Retainer
Best for continuous product and platform evolution with steady weekly output.
FAQ
How do you scope work?
We run a short discovery phase to define goals, constraints, dependencies, and measurable outcomes before build starts.
How do you handle security?
We apply secure coding practices, role-based access, validation, logging, and deployment hardening by default.
Can you work with existing codebases?
Yes. We can audit, stabilize, and extend legacy or active codebases while preserving delivery velocity.
What if priorities change?
We manage change through transparent backlog reprioritization and impact-aware milestone updates.
Do you provide support after launch?
Yes. We offer post-launch support, monitoring, and incremental improvement options.
Will we own the product and infrastructure?
Yes. Your company retains ownership of the code, assets, documentation, and infrastructure produced for the engagement.
