Back End Development Company

Never worry about unpredictable user loads or cross-device compatibility anymore: we develop a back-end for native (Java/Kotlin, Swift) and cross-platform (Flutter, React Native, Kotlin Multiplatform) applications that will run on different OS and devices like iOS and Android.

• Mobile banking backends. We build PCI-ready mobile banking backends with KYC/AML flows, transaction histories, limits management, and fraud checks for iOS and Android apps.
• Courier apps. We power courier and driver apps with trip assignment, GPS tracking, delivery status updates, and proof-of-delivery sync to your core systems.
• Field operations. Our back end application development services deliver solutions for operators and technicians with work orders, asset status, checklists, and downtime reporting tied into ERP, MES, or CMMS.
• Push messaging. We implement push and in-app messaging backends that trigger alerts for payments, shipments, incidents, and account activity in real time.
• Offline-first sync engines. We design offline-first sync engines with local caching and conflict resolution for unstable networks in warehouses, plants, and on the road.

A well-architected mobile backend protects the business as the product scales. It enables mobile products to behave consistently across devices and stay stable under peak demand.

Switch to cloud infrastructure to scale up and down easily, handle heavy loads, and eliminate latency issues. Let us assist you in migration to public, private, or hybrid clouds. We support AWS, Google Cloud, Azure and other cloud vendors.

• Cloud migration backends. We handle Java back end development migrations to AWS, Azure, or GCP with a mix of re-hosting, re-platforming, and targeted refactoring.
• Microservices architectures. We design and implement containerized microservices with Kubernetes, service discovery, centralized configuration, and full observability.
• Serverless workloads. We build serverless APIs and event handlers on Lambda, Azure Functions, or Cloud Functions for spiky workloads like campaigns, billing, and ETL.
• Multi-tenant SaaS cores. We architect multi-tenant SaaS backends with tenant isolation, subscription management, RBAC, and metered usage tracking.
• Cloud reliability engineering. We set up CI/CD, infrastructure as code, autoscaling, backup and disaster recovery, monitoring, and alerting for production cloud workloads. These foundations allow backend slices to deploy independently, scale under load, and integrate into live systems without interrupting users or operations.

Cloud backend solutions provide the ability to scale capacity in line with demand while keeping performance stable and operating costs under control. A well-executed cloud migration reduces infrastructure constraints, improves system resilience under peak loads, and gives teams the flexibility to adapt architecture as products and markets evolve, without latency becoming a limiting factor.

Whether it’s a large-scale system, web portal, or IoT infrastructure, our team will deliver high-load performance systems with enhanced stability. We will leverage server-side logic and infrastructure to ensure smooth and high platform performance.

• Customer and partner portals. We create secure portals for customers, agents, shippers, and suppliers with tailored roles, self-service tools, and API connectivity.
• Enterprise system extensions. We extend ERP, MES, WMS, and TMS with custom backends for new workflows, events, and integration endpoints that the core system lacks.
• Analytics backends. We use Python back end development to aggregate operational, financial, and logistics data into backend services that power dashboards, exports, and alerting.
• Pricing and order engines. We implement pricing, quoting, and order management engines with configurable rules, approvals, and lifecycle tracking.
• Workflow automation cores. We build workflow backends that orchestrate underwriting, credit approvals, shipment exceptions, maintenance requests, and similar processes.

For the business, this means stable back end web development that ensures platforms continue to perform as demand grows, without sudden slowdowns, outages, or costly firefighting. A stable backend turns growth into a controllable process and allows the product to evolve without performance becoming a limiting factor.

Developing versatile solutions for mobile, web, and other back-end to improve your current interoperability level, enable multi-platform functionality, share data across systems, and leverage seamless integration with third-party services. Using REST API, GraphQL, WebSocket, Hooks, and EventStreams.

• Payment APIs. We integrate payment providers such as Stripe, PayPal, ACH, and wallets and build reconciliation logic, webhooks, and payout flows.
• Banking and KYC APIs. We connect to banking cores, KYC/AML providers, and credit bureaus through secure APIs with strict access control and auditing.
• Logistics APIs. We integrate carrier and telematics APIs for parcel, freight, GPS tracking, route status, and proof-of-delivery data.
• Industrial IoT APIs. We expose and consume APIs for IIoT platforms, gateways, and machine data, streaming telemetry into scalable cloud backends.
• Public and partner APIs. We design and operate API development back end platforms with OAuth2, rate limiting, versioning, and developer onboarding tools. Stable API contracts and versioning strategies allow frontend and partner teams to evolve independently, while backend modernization continues in parallel.

Strong API design turns fragmented systems into a single, reliable business platform. It removes integration friction, accelerates feature delivery across platforms, and allows data to flow freely between products, partners, and services—without instability or manual overhead.

Failing to get optimum app performance? Devox Software can rehaul the entire solution infrastructure, leaving the front end intact. Rebuild existing systems to reduce development, infrastructural and supporting costs, enhancing the code base quality on the way.

• Backend audit roadmap. We analyze codebases, dependencies, data flows, and infrastructure to define a clear, risk-aware refactoring roadmap with measurable performance and cost outcomes. The roadmap is organized into independent slices, each delivering production-ready improvements with clear ownership, quality gates, and visible impact on performance and maintainability.
• API refactoring integration. We deliver API development back end improvements by redesigning and stabilizing backend APIs using REST or GraphQL to improve scalability, integration reliability, and long-term maintainability.
• Microservices refactoring. We break down tightly coupled backends into well-defined services to enable independent scaling, faster releases, and architectural clarity.
• Cloud-ready refactoring. We refactor backend components for cloud-native operation and align them with automated CI/CD pipelines to support predictable, low-risk delivery.
• Performance optimization. We optimize backend performance through data access tuning, caching, and runtime observability to keep systems responsive as load and complexity grow.

In many back end development projects, refactoring restores control over performance and costs without disrupting users or ongoing operations. We decompose backend systems into delivery slices aligned with business flows. Each slice moves through audit, refactor or rewrite, automated testing, and production release on its own timeline, allowing teams to modernize continuously while feature development moves forward.

If you need a close local infrastructure for an internal network, we can develop a custom server exclusively for your company’s needs. Relevant for a product that has unique requirements like high-performance processing, advanced security needs, or low-latency demands.

Get an exhaustive test coverage of your existing back-end. We’re conducting security and stress testing to trial-run your app’s back-end and evaluate its performance under pressure, resistance to high load or attacks, and overall capacity. No stones unturned, no potential issues undetected.

• Backend testing strategy. We define a backend testing strategy that aligns business logic, integration risks, and system boundaries with meaningful test coverage.
• Automated backend testing. We implement automated tests that validate core logic, service interactions, and data consistency across backend components.
• API contract testing. We test backend APIs against defined contracts to ensure reliability, backward compatibility, and safe evolution of integrations.
• Performance load testing. We validate backend behavior under realistic load scenarios to uncover bottlenecks before they impact users or operations.
• Regression validation. We run regression testing pipelines that verify backend stability as changes move through CI/CD toward production.

By validating business logic, data integrity, and service interactions before changes reach production, teams reduce outage risk, avoid revenue-impacting defects, and keep delivery predictable as systems evolve. Reliable backend testing shortens release cycles, lowers the cost of fixing issues late in development, and builds confidence that refactoring or scaling efforts will not disrupt customers or internal operations.
