Frequently Asked Questions

Can you scale my existing engineering team with dedicated developers?

Yes, we offer a "Team Augmentation" model where our specialized engineers become an extension of your in-house team, working directly under your management to accelerate your roadmap.

What is your expertise in database architecture and optimization?

We design high-performance database schemas using PostgreSQL, SQL Server, and NoSQL systems like Redis, specifically optimized for fast query execution and data integrity under high loads.

How do you handle automated deployments and CI/CD?

We automate our deployment pipelines using GitHub Actions or Azure DevOps. This ensures that every code change is automatically tested and deployed safely, reducing human error and system downtime.

Do you develop native or cross-platform mobile applications?

We develop both. Depending on your performance requirements and budget, we offer native development (Swift/Kotlin) or high-quality cross-platform solutions using React Native or Flutter.

How involved will our team be in the development process?

Very involved. As part of our Agile process, you will have access to sprint demos and project management tools like Jira. We prioritize continuous feedback to ensure the product matches your vision.

Can you help us migrate a legacy application to a modern framework?

Legacy modernization is one of our core strengths. We can systematically refactor old codebases (such as .NET Framework) into modern, cloud-ready .NET Core architectures without disrupting your operations.

What is your approach to high-performance mobile game engineering?

We utilize Unity and C# to build engaging mobile games. Our focus is on optimized asset management, real-time multiplayer synchronization logic, and ensuring smooth frame rates across all target devices.

How do you determine project pricing and engagement models?

We offer two primary models: Fixed-Price for well-defined project scopes and Time & Materials (T&M) for evolving products. We work with you to find the most transparent and cost-effective approach.

Do you offer post-launch technical maintenance and support?

Yes, we provide flexible Service Level Agreements (SLAs) for ongoing maintenance, security updates, and performance optimization to ensure your platform scales seamlessly as your business grows.

Can you integrate third-party APIs and legacy ERP systems?

Absolutely. We have extensive experience integrating various third-party services, including payment gateways (Stripe), CRM systems (Salesforce), and custom ERP solutions to create a unified business ecosystem.

What is your experience with cloud infrastructure and DevOps?

We are experts in managing cloud environments on AWS and Azure. We implement containerization using Docker and orchestration with Kubernetes to ensure your application is resilient and highly available.

How do you handle Intellectual Property (IP) and confidentiality?

All partnerships are protected by US-governed NDAs. Upon project completion and final payment, full ownership of the source code and all intellectual property is legally transferred to the client.

Do you provide full-cycle UI/UX design services?

Yes, we offer end-to-end product development, including user research, wireframing, and high-fidelity UI/UX design. We ensure that the technical architecture and the user experience are perfectly aligned from the start.

How do you ensure the quality and maintainability of the source code?

Our engineering process includes mandatory peer code reviews, automated unit testing, and integrated QA cycles within every sprint. We adhere to SOLID principles and Clean Architecture to minimize technical debt.

What is your primary technology stack for enterprise B2B applications?

We specialize in the .NET 8+ ecosystem for high-performance backend engineering and React/Next.js for modern, SEO-optimized frontends. This combination ensures enterprise-grade security with scalable user interfaces.

How do you ensure the security of our intellectual property (IP)?

We operate with strict legal frameworks. All our partnerships are governed by comprehensive NDAs and IP protection agreements. Technically, we follow OWASP security standards and implement industry-leading encryption and secure coding practices to protect your data and logic.

Can you scale our existing legacy systems?

Absolutely. We specialize in Legacy System Modernization. Whether you are running on older .NET frameworks or monolithic architectures, we can refactor and migrate your systems into high-performance, cloud-native microservices using .NET 8+ and React/Next.js.

What is your software development methodology?

We follow a strict Agile/Scrum framework. This involves bi-weekly sprints, regular code reviews, and continuous integration (CI/CD) pipelines. This iterative approach allows us to remain flexible, handle changing requirements efficiently, and deliver high-quality code faster.

How do you manage project communication across different time zones?

Communication is our priority. We utilize Agile/Scrum methodologies and maintain overlapping working hours with US time zones (EST/PST). We use Slack for real-time updates, Jira for task tracking, and scheduled weekly syncs to ensure total transparency throughout the development lifecycle.

Why should US-based companies partner with L21?

L21 provides high-end engineering talent with deep expertise in the .NET ecosystem and modern web frameworks like Next.js. We offer a unique advantage: Silicon Valley-grade technical standards combined with cost-effective, scalable development teams, ensuring a high ROI for your B2B projects.
