Custom Software Development

Custom software built by senior engineers: scalable Python/Django backends, real time APIs, React and operator grade dashboards, and the migrations to get you there from whatever you run today.

Custom Full Stack Development

GNXSoft builds operational command centers. the backend engines that process mission critical data and the frontend interfaces that make it actionable. We engineer software for enterprises that need more than templates: real time data processing, complex business logic, and systems that scale.

The Challenge

Enterprise operations generate massive data volumes from disparate sources. IoT sensors, fiscal devices, ERP systems, third party APIs. Generic software can't handle specific workflows, compliance requirements, and real time processing demands. Off the shelf dashboards collapse under the weight of real operational data: thousands of concurrent streams, sub second updates, and business logic that can't be configured with drag and drop.

Backend Engineering

  • API Architecture. RESTful and GraphQL APIs designed for high throughput workloads. Rate limiting, OAuth2/JWT authentication, versioning, and OpenAPI documentation from day one.
  • Real Time Data Pipelines. Event driven architectures using WebSockets, Server Sent Events, and message queues (RabbitMQ, Celery) for sub second data delivery.
  • Database Engineering. PostgreSQL for transactional data, TimescaleDB for time series telemetry, Redis for caching and real time state. Schema design optimized for query performance at scale.
  • Microservices & Monolith. We choose the right architecture for the problem. Not everything needs microservices, not everything fits in a monolith. Optimized for operational simplicity and team velocity.
  • Task Processing. Background job queues, scheduled tasks, and workflow orchestration for heavy computation, report generation, and data synchronization.

Frontend Engineering

  • Operational Dashboards. React based command centers with live data visualization, interactive charts, filterable tables, and role based access. Designed for operators who spend 8 hours a day on the screen.
  • Progressive Web Applications. Offline capable, installable, mobile responsive applications that work on any device without app store distribution.
  • Responsive Design. Mobile first interfaces that adapt to any screen size, from warehouse tablets to executive monitors.
  • Accessibility. WCAG 2.1 compliant interfaces ensuring usability for all users.

Integration & Data

  • Third Party Integration. REST APIs, SOAP services, webhooks, database replication, and file based interfaces for any external system.
  • Data Migration. Safe, validated migration from legacy systems with zero downtime cutover strategies and rollback plans.
  • Reporting & Analytics. Custom reporting engines with export to PDF, Excel, and CSV. Scheduled reports, ad hoc queries, and business intelligence dashboards.

Technology Stack

Python 3.12+ / Django 5.x for backend. React / Next.js for frontend. PostgreSQL, Redis, RabbitMQ for data. Docker / Kubernetes for deployment. GitHub Actions / GitLab CI for continuous integration. Comprehensive test suites with 85%+ code coverage.

Proven Results

  • Enterprise platforms serving 50,000+ daily active users
  • APIs handling 10,000+ requests per second at peak
  • 99.99% uptime across production deployments
  • Average 40% reduction in manual operations after dashboard deployment
