Why Trust Zazz For
Hiring Kotlin Developers?

Customized Mobile App Development

Customized Mobile App Development

Your business is unique, so your app should be too. Zazz takes the time to deeply understand your specific goals, target users, and technical needs. This insight allows us to design and architect custom Kotlin solutions tailored to your exact requirements from the ground up. Our developers work collaboratively with you to translate your vision into reality through an app built for your objectives.

Results-Driven Kotlin Talent

Results-Driven Kotlin Talent

The success of your app hinges on the skills and commitment of the developers who build it. That's why Zazz is rigorous in vetting Kotlin talent for proven expertise, experience, and dedication to achieving outcomes. We don't just hire for output, we hire for impact. Our developers are aligned with your business KPIs from day one and laser-focused on crafting an app that delights your users.

Expedited App Delivery

Expedited App Delivery

Zazz leverages agile development methodologies to deliver Kotlin projects faster. Our iterative approach gets you working software quickly upfront, rather than waiting months for a fully featured product. The bare essentials come first, allowing you to test assumptions and get user feedback right away. We work in rapid cycles to refine and add functionality in priority order. This fail-fast, deliver-faster mentality compresses timelines dramatically compared to waterfall development.

Uncompromising Quality Processes

Uncompromising Quality Processes

Before any Kotlin code reaches your hands, it undergoes rigorous testing to catch bugs early and often. We utilize automated testing at the unit, integration and UI levels to maintain quality over time as new features get built. Extensive manual testing simulates real-world usage. Your team has ample opportunity for user acceptance testing and feedback before launch.

Flexible Engagement Models

Flexible Engagement Models

Zazz offers a range of flexible engagement models to meet your needs as they evolve. For long-term augmentation, our dedicated team model allows Kotlin developers to become fully integrated members of your staff. To scale up for a major project, our extended team model rapidly spins up additional resources so you can execute ambitious initiatives without permanent hires.

Seamless Collaboration

Seamless Collaboration

With Zazz there are no communication disconnects or misalignment. Your account manager and Kotlin team participate together in agile ceremonies, ensuring everyone is looped into progress and priorities. Issue tracking and daily standups provide transparency, while tools like Slack and Zoom enable real-time collaboration across time zones. Our offshore teams are thoughtful in maximizing overlap with your working hours for responsiveness.

Time Zone Conscious Teams

Time Zone Conscious Teams

To facilitate productivity, Zazz thoughtfully composes teams matching your time zone as closely as possible. Do you need an early riser to sync with West Coast colleagues? A late shift for UK meetings? We staff your project with the optimal mix so key personnel is online when you are. There are no waiting hours for critical feedback. Backfill developers provide round-the-clock momentum.

Scalability On Demand

Scalability On Demand

As your business grows, so can your app development team. Zazz maintains a deep bench of qualified Kotlin developers allowing us to scale your capacity up or down on-demand. Our thorough onboarding ensures new resources are productive immediately. We also design apps using extensible architectures so that additional features, traffic, and data can be handled without reinventing the wheel.

Minimized Disruption

Minimized Disruption

If a resource needs to roll off your Kotlin project, Zazz ensures continuity so you won't miss a beat. Our replacements are fully briefed to pick up work mid-stream for smooth handoffs. Documentation and IP are carefully retained to prevent any loss of knowledge. Any code dependencies or specialty skills are mapped out upfront as well. Our process for transitioning team members enables uninterrupted progress with minimal disruption.

Frequently Asked Questions

1. How do you hire the best Kotlin Developers?

+

We utilize a rigorous recruitment process to hire only the top 1% of Kotlin developers. Candidates must pass stringent technical screening and assessments based on real-world scenarios. We verify skills through code samples, tech discussions, and hands-on problem-solving. Only those demonstrating exceptional expertise in Kotlin, backend frameworks like Spring Boot, and modern architecture patterns are selected. In addition, we check references to validate the experience listed on resumes. The result is you get an elite team of developers proven to create high-quality, scalable Kotlin applications on time and on budget.

2. What is the average experience level of your Kotlin Developers?

+

Our Kotlin developers average 3-10 years of hands-on experience architecting and building production-grade applications using the language. Many possess even longer background in Java which allows them to apply that knowledge in Kotlin contexts. Almost all have worked on enterprise Kotlin systems from start to finish, giving them insight into the full development lifecycle. We aim for mid-to-senior level developers who can hit the ground running on projects using best practices rather than juniors still learning the ropes.

3. How do you ensure the expertise of Kotlin Developers you provide?

+

We utilize robust quality management processes to guarantee all developers provided meet the highest standards of expertise. First, we only source candidates with demonstrated Kotlin mastery per our recruiting methodology. Once on board, they undergo immersive training on our processes, documentation standards, code quality guidelines, security protocols, and more. Their initial code undergoes peer review to affirm competence.

4. What is the pricing model for hiring Kotlin developers?

+

We offer flexible pricing models to suit your needs:
Part-Time Hiring Model – Pay for just 4 hours/day. Minimum 30 days. Ideal for projects requiring fractional resources or sporadic effort.
Full-Time Hiring Model –Have developers dedicated 8 hours/day. Minimum 30 days. Best for steady development work or interim staffing gaps.
Hourly Hiring Model – Pay per hour as needed. Minimum 80 hours. Great for short-term projects requiring targeted skill sets.
The minimums provide cost-efficiency while allowing flexibility in how talent is leveraged. All options give you top Kotlin developers minus permanent headcount costs.

5. Do you offer flexible engagement durations?

+

Absolutely, we accommodate any engagement duration you need. Many clients leverage our developers long-term like extended team members. We’re also adept at short-term projects requiring just weeks or months of effort. Our minimums are modest so you get maximum flexibility. There's no lock-in. Extend engagements or ramp developers down as your priorities change.

6. What if I am not satisfied with a Kotlin developer’s performance?

+

We back our developers 100% and provide a satisfaction guarantee. If any resource fails to meet expectations, just notify us within 10 days. We’ll swiftly replace them with another candidate free of charge. We stand by the quality of talent we supply – anyone not cutting it will be swapped until you’re completely satisfied. You can count on us to make it right.

7. What if my project requirements change during the engagement?

+

Not to worry, requirements changing mid-project is par for the course. Our developers are accustomed to shifting priorities. We take an agile approach so modifications can be accommodated at any stage. Your account manager will collaborate closely with you to refine specifications, rescope work, and realign resources as needed. Our flexible agreements make pivoting painless. We’ll help assess effort estimates and schedule implications too. Our focus is making sure you get an outcome that solves your current business needs, even as they evolve.

8. How do you handle communication between clients and developers?

+

Seamless communication is integral to our model. Your account manager will set up introductions and project kickoff calls to establish working relationships between you and the development team. They will agree on preferred channels and cadences for check-ins based on your preferences.

9. Is there a minimum or maximum duration for engagement?

+

We customize engagements to your needs, so there are no set minimums or maximums on how long you can leverage our developers. Most initial contracts span 3-6 months to complete defined milestones. But we routinely support clients much longer across years and multiple initiatives as trusted partners. Ramp up or down at your discretion. We structure flexible agreements and pricing to meet your variable requirements over time.

10. Do you provide NDA (Non-Disclosure Agreement) for confidentiality?

+

Absolutely, we execute comprehensive NDAs with all our clients before project kickoff to protect intellectual property and proprietary information. All developers are contractually bound to keep your product details, designs, and any other sensitive data totally confidential both during and after engagement. We follow best practices like code repositories with restricted access and encrypted credentials to safeguard your IP.

Zazz can turn your vision into a reality. Let’s
collaborate to create something groundbreaking!
