Service Offering

We understand that when organizations outsource AWS development services, they expect structured delivery, dependable execution, and technical expertise aligned with up-to-date standards. That’s why our service line is shaped around these priorities and the demands of modern applications.

Architecture Design and Implementation

Get a resilient foundation that minimizes risks, reduces maintenance effort, and aligns with your long-term product goals. We create scalable AWS architectures tailored to your application’s workload, performance and security criteria. Our engineers define the core components, execute infrastructure automation, and establish the operational guardrails needed for stable production performance.

Custom AWS Application Development

We design and build cloud-native applications on AWS using serverless, microservices, and container-based architectures. Our team delivers systems that scale automatically, run reliably under load, and reduce long-term operational effort. We help our customers launch faster, optimize application performance, and maintain predictable cloud spending for software operations.

AWS Application Rebuild

We reconstruct legacy applications by redesigning their architecture, rewriting critical modules, and replacing brittle components with AWS services. The process covers replacing legacy logic with scalable patterns, data migration, API restructuring, event-driven communication, and automated deployment pipelines. The rebuilt application becomes faster, easier to maintain, and prepared for long-term growth in the cloud.

API Development and Integration

Our team connects third-party services, and integrates any internal systems to remove bottlenecks, reduce manual processes, and support reliable feature delivery as your product evolves. We create RESTful and event-driven APIs optimized for high availability and efficient data exchange between your core services, AWS components, and the external platforms your product interacts with (billing systems, analytics tools, CRMs, etc.).

Frequently Asked Questions

Do you work with existing AWS infrastructure or only build from scratch?

We support both scenarios. And in both cases, you get an AWS foundation that supports long-term development, stable operations, and steady evolution of your product. If you already have an AWS environment, our team can step in to assess its architecture, performance, and security posture. This includes reviewing service configurations, analyzing cost efficiency, identifying reliability risks, and checking alignment with Well-Architected Framework. Based on these findings, we help stabilize the environment, implement missing automation, modernize components, and extend your system with new features or integrations.

Can you help choose the right AWS services for my application development?

Yes. Selecting the right combination of AWS toolkits is one of the most important decisions in any cloud project, and it strongly influences performance, scalability, maintainability, and long-term cost. Our team evaluates your functional specifications, data flows, security needs, user demand, and technical constraints to determine the most effective AWS stack for your application. This includes deciding between serverless or containerized approaches, choosing the right database engines, defining event-driven patterns, planning storage strategies, and setting up the operational tooling needed for reliable production use.

At the end of this phase, you receive a clear, well-structured architecture plan that outlines which Amazon Web Service to use, why they are the best fit, and how they support the overall  product’s roadmap. In this way we ensure the application is built on a strong foundation that remains scalable, secure, and cost-efficient as the software evolves.

How can you keep my AWS-based application maintained after development is done?

Beyond actual development, we can ensure your application runs reliably in production. We call it full lifecycle support. Monitoring, optimization, cost control, and operational support are built into our approach, so your product stays stable as usage grows. You get support services that evolve with your software. As new requirements appear, features change, or integrations become necessary, our team is already familiar with your architecture and can deploy updates quickly and safely.

How does an AWS development partner support long-term software scalability and development cost control?

A vendor like Romexsoft helps you make architectural and technical decisions that support software’s expansion potential without adding unnecessary complexity or causing costly rework later. By selecting services that scale automatically, structuring workloads to handle varying traffic patterns, and designing components that operate efficiently under load, your application gains the ability to grow without stability issues.

Cost efficiency also improves because an experienced partner understands how different AWS services behave, how pricing models vary, and which configurations keep operational expenses under control. This includes optimizing compute choices, implementing proper storage tiers, designing smart data access patterns, and using automation to avoid asset waste.
