“Take down this wall!”
Tandem believes that better solutions are created when we take down the walls separating stakeholders. Perhaps your development team is siloed off from your support department. Maybe marketing is leaning too heavily on surveys and isn’t talking to enough end-users. We’ve developed an expansive set of tools and techniques to eliminate these barriers.
For Tandem, digital strategy is the process of crafting a plan that will help you reach your goals. We work with you and your team to not only develop a shared understanding, but to challenge assumptions and bring fresh eyes to your organization’s problems.
Defining Goals
Who are the main stakeholders?
What do they want?
How do we measure those things?
Understand the Problem
Define the audience through user interviews, analytics, and personas.
Use a journey map to outline their current experience of your services
Identify critical pain points and areas for improvement
Architect Solutions
Host interactive sketching sessions to work-through potential solutions
Create mobile-first wireframes to formalize information architecture
Use moodboards and style tiles to iteratively develop a visual language formalized in a style guide
Code an interactive, in-browser prototype
Test + Iterate
Review solutions at each step with stakeholders
Conduct user testing sessions with our prototype
Iterate until we’re ready to develop our concept
Tandem uses agile processes to bring stakeholders closer to the development process and coders closer to the business problems they’re solving.
Manage Projects Better w/Agile
Sprint schedules based around your business needs
Cross-functional teams bring diverse stakeholders together
Kanban boards make issue management easy
See issue history with code and conversation, side-by-side
Better QA = Less Bugs
Catch regressions with automated testing
On-demand QA environments to review important changes
Transparent code review to ensure fast, functional, and secure code
More Frequent, Predictable Releases
Regular, frequent deployments show progress in real-time and prevent large regressions
Sprint analytics establish a pace of development to accurately predict progress
Worried that your project has become an insatiable beast that devours development time? Victim of a revolving door of unreliable contractors?
Tandem helps you take back control of your technical destiny. We find the best way to achieve your business goals with your current resources. For some organizations, that means hiring developers or retraining your current team. For others, that means a targeted one-time refactoring of legacy software.
Whatever the solution, we’ll always give you an honest assessment with actionable advice to find the path forward.
Troubleshooting Pain Points
Identifying performance bottlenecks
Solving perplexing problems and errors
Recovering hacked sites
Re-architecting Legacy Systems
Picking the best replacement technology

Hiring and Training Developers
Interviewing and finding great developers
Train your existing team on modern best practices
Tandem believes strongly in a “teach a developer to fish” philosophy. Where many consultancies make themselves a long-term dependency, we want your organization to succeed on its own terms. Often, that means helping to train your team to support new technologies and learn better ways of developing software.
Drupal Training
We've trekked across the United States and beyond giving Drupal trainings to our clients and at conferences. Accelerate your team's understandings of this powerful (but sometimes idiosyncratic) content management system with our experts. A few trainings we've offered in the past include...

DevOps Training
DevOps concepts like continuous integration and automated testing can create huge performance gains for your team. However, when you're always focused on the next feature or pushing for an upcoming deadline, it's difficult to make the investments in learning to introduce these needed changes. Our trainings help catalyze DevOps transformations, accommodating your team's busy schedule.

We are two individuals working freelance in our own specialisms who have joined forces to provide a web design service for a few select clients. We are based in the East of England but are happy to consider commissions from anywhere.
Our web development work is now exclusively based on use of the Backdrop content management system because we believe this offers an ideal solution for small to medium organisations who need a site that is easy for them to keep up-to-date with new content.
We would be pleased to help with development of web sites for individuals or small organisations, either as upgrades from existing sites or as new ones.
Based out of Ottawa, Canada, we help build and deploy Backdrop and Drupal powered web applications for both public and private sector organizations. We have a range of clients varying from individuals or small businesses to full enterprise or government based entities.
Through the affordability of open source technology, we're helping not-for-profits operate more efficiently, develop new services, and increase the benefits they provide to their communities. Among other services, we build and support content & contact relationship management systems, and integrated solutions for custom data collection and analysis.
We have had a major focus on Drupal and CiviCRM as a CMS/CRM combo, and we are interested in helping not-for-profits also build sites with Backdrop CMS with or without CiviCRM.
