## Services

### Full-cycle Development
Tallium designs and builds software products end-to-end. From UX research and requirements engineering through development, QA, and production release. A typical MVP is delivered in 2-4 months. Clients get a fully managed product team (PM, designers, engineers, QA) without the overhead of building one in-house. Costs are up to 50% lower than comparable in-house development.
- [Full-cycle Development](https://tallium.com/en/services/development)

### Software Team Augmentation
Tallium staffs dedicated teams from R&D centres in Rzeszów (Poland) and Kyiv (Ukraine), drawing on 100+ in-house specialists and a 10K+ vetted talent database. Available roles: frontend, backend, mobile, QA, cloud, DevOps, UI/UX, BA, and PM. Core team profiles are ready to start within 1-2 weeks; custom hiring takes 3-4 weeks. Teams scale up or down as the roadmap changes, with no long-term hiring overhead. Engagement by the hour, week, or month. 89% client retention rate, 92% employee retention.
- [Dedicated Team](https://tallium.com/en/services/dedicated-team)

### Digital Transformation Consulting
Tallium helps engineering and product teams move faster by implementing Agile delivery practices, removing process bottlenecks, and introducing AI where it creates measurable operational value. The service combines process consulting, team coaching, and hands-on implementation. Clients have used this to cut release cycle times and align distributed teams around shared delivery standards.
- [Digital Consulting](https://tallium.com/en/services/digital-consulting)

### Product Concept & Design
Tallium offers four design service tiers: Lean Validation ($4,950 / 2 weeks: competitor analysis, user flow mapping, MVP scoping, 2-3 design concepts, app architecture, and a development roadmap), Product Blueprint, End-to-End Product Design (2-4 design sprints with user testing), and Enterprise 360° Discovery. Results: Prostor app reached 500K+ downloads; NOWO saw 30% signup increase; Mangold's redesigned trading platform generated zero support tickets.

## Expertise

### AI and Machine Learning
Tallium helps product teams integrate AI into existing products or build new AI-powered features from scratch. A custom AI agent, connected to the client's knowledge base and business systems, is delivered in 4 weeks for $7,950. Other services include AI consulting and AI in SDLC implementation, no-code AI automation, and custom AI feature development. Our proprietary solutions (AI marketing suite, AI model matcher, Knowledge AI, and Digital readiness map) reduce build cost and time-to-market.
- [AI Consulting](https://tallium.com/en/expertise/ai-consulting)

- [Web & Mobile App Development](https://tallium.com/en/expertise/web-and-mobile-app)

### Big Data & Data Science
Tallium solves six data engineering challenges: data overload (intelligent storage and retrieval), poor data quality (cleaning and transformation pipelines), data security (encryption and regulatory compliance), real-time processing (streaming analytics for instant decisions), scalability (architectures that grow with data volume), and ROI optimisation (cost-effective storage and processing that deliver measurable business returns). Relevant for companies scaling their data operations or moving from spreadsheet-based reporting to automated data systems.
- [Big Data](https://tallium.com/en/expertise/big-data)

### Web 3.0 & Blockchain
Tallium develops blockchain solutions covering smart contract development, wallet integration, and full decentralised application (DApp) builds. Delivery spans architecture design, on-chain development, security audit, and production deployment. Applicable across Ethereum and other major chains. Primary use cases: tokenisation, DeFi protocols, compliance-grade transaction infrastructure, and Web3 product builds for fintech and financial services companies.
- [Blockchain](https://tallium.com/en/expertise/blockchain)

### Cloud-native Services
Tallium builds, migrates, and optimises cloud-native applications using containers, Kubernetes, serverless functions, and managed services across AWS, Google Cloud, Azure, Digital Ocean, and Firebase. Three engagement scopes: migrating on-premise or monolithic systems to the cloud, building new cloud-native applications from scratch, and optimising existing cloud infrastructure for cost and performance. Reduces operational overhead and ensures predictable scaling.
- [Cloud-native Services](https://tallium.com/en/expertise/cloud-native)

### DevOps & Security
Tallium addresses six DevOps bottlenecks: high development costs, slow release cycles, poor operational transparency, low app quality, unscalable systems, and unstable infrastructure. We design and implement CI/CD pipelines, containerised infrastructure, and cloud environments to help engineering teams release faster and more reliably. Services include CI/CD pipeline design, containerisation (Docker, Kubernetes), Infrastructure as Code provisioning, cloud cost optimisation, automated monitoring and alerting, and version-controlled documentation. We reduce release cycle time and prevent the infrastructure cost creep that affects scaling teams.
- [DevOps Services](https://tallium.com/en/expertise/devops-services)

### QA & Test Automation
Tallium provides dedicated QA teams that combine manual and automated testing to catch up to 98% of bugs before release. Manual testing covers ad-hoc, exploratory, error handling, UX validation, and compatibility scenarios. Automated testing handles rapid regression detection, large-scale concurrent execution, and CI/CD-integrated scripts. Services include test strategy, performance testing, security testing, and usability verification.
- [QA & Test Automation](https://tallium.com/en/expertise/qa-and-test-automation)

### Software Modernization & Re-engineering
Tallium modernises software through six approaches: re-architecting monoliths into microservices, replacing unsupported legacy tech stacks, database tuning for slow queries and growing datasets, complete re-engineering of crash-prone systems, cloud migration from on-premise infrastructure, and full product redesign when UX no longer meets market expectations. Includes technical audit, phased delivery, and 45-day free post-launch support. Result: reduced technical debt, lower maintenance costs, and product teams unblocked from ageing architecture.
