Services
What we build and how.
Five focused areas where TEQ DEN TRANSYLVANIA takes technical ownership — from greenfield product engineering to platform modernization and process automation.
Product Engineering
Build with ownership from day one.
- Web Platforms
- APIs
- Mobile Apps
- Dashboards
- SaaS
We build products with solid technical foundations — not just to ship the first version, but to make the product easy to evolve, maintain, and own over time. From the first design of the data model to the structure of the API and the component architecture on the frontend, every decision is made with long-term maintainability in mind.
What we deliver
- Web platforms and SaaS applications
- RESTful and GraphQL APIs
- Admin dashboards and internal interfaces
- Mobile applications (iOS & Android)
- Product features on existing platforms
- Greenfield technical implementations
Ideal for
Companies starting a new product, launching a new feature set, or rebuilding a platform with proper engineering ownership.
Discuss this service →Platform Modernization
Evolve legacy systems without disruption.
- Refactoring
- Performance
- Architecture
- Tech Debt
- Optimization
Technical debt accumulates in every product. The question is whether it's managed — or allowed to compound until it becomes a crisis. We help teams identify what to address now, what to plan for, and how to improve systems incrementally without breaking what works. We focus on real, measurable improvements — not rewrites for the sake of rewrites.
What we deliver
- Architecture analysis and improvement plans
- Strategic refactoring with test coverage
- Database schema and query optimization
- Legacy flow identification and replacement
- Performance profiling and targeted improvements
- Dependency audit and upgrade paths
Ideal for
Products that have grown organically and carry technical debt that is beginning to slow down development or create reliability issues.
Discuss this service →Business Process Automation
Turn manual work into reliable systems.
- Internal Tools
- Workflows
- Automation
- Reporting
- Dashboards
Repetitive manual work is expensive and error-prone — but often it persists simply because no one has had the time to build the tooling to replace it. We build internal tools, automation pipelines, and operational dashboards that give your team visibility, reduce toil, and make your processes repeatable and auditable.
What we deliver
- Internal operational dashboards
- Approval and review workflow systems
- Data aggregation and reporting pipelines
- Notification and alerting integrations
- Document generation and export tools
- Process automation for repetitive tasks
Ideal for
Operations teams, finance functions, or product teams that rely on manual steps, spreadsheets, or ad-hoc scripts to run key processes.
Discuss this service →Web & Mobile Development
Full-stack, end-to-end, production-ready.
- React
- React Native
- Node.js
- Express
- MongoDB
- PostgreSQL
We work across the modern JavaScript ecosystem — building responsive web applications, cross-platform mobile apps, backend APIs, and everything in between. Our stack is chosen for productivity, performance, and long-term maintainability. We don't chase frameworks for novelty — we use what makes products excellent.
What we deliver
- React web applications and SPAs
- React Native mobile apps (iOS & Android)
- Node.js / Express backend APIs
- MongoDB and PostgreSQL database design
- Third-party API and service integrations
- Authentication, authorization, and security layers
Ideal for
Companies that need reliable, full-stack execution on web and mobile — with a team that understands both the frontend experience and the backend infrastructure that powers it.
Discuss this service →Technical Consulting
Clarity before commitment.
- Architecture
- Feasibility
- Performance
- System Design
- Planning
Not every technical challenge requires writing code immediately. Sometimes the most valuable thing is a clear, honest assessment of what you're dealing with — what the architecture can support, where the risks are, and what the realistic options are. We bring a product-minded technical perspective to architecture reviews, feasibility assessments, and system design work.
What we deliver
- Architecture and codebase reviews
- Product feasibility analysis
- Performance audits and bottleneck identification
- System design for new products or features
- Technical planning and roadmap input
- Build vs. buy analysis and vendor evaluation
Ideal for
Teams facing a major technical decision, evaluating a platform, considering a rebuild, or trying to understand the true cost of their current architecture.
