Our Technology Stack | Java, React, AWS, Kubernetes & More – Zuplon

The Stack We Work In Every Day

These aren't technologies we've glanced at — they're the tools our engineers use daily to build, deploy, and scale production systems for real businesses.

Languages & Frameworks

Our engineering teams are deeply proficient in the languages and frameworks that power modern enterprise software.

Java

Java

Our primary language for enterprise backend systems. We build robust, high-throughput services using Spring Boot, Spring Cloud, and Java 17+ with clean architecture principles.

Python

Python

Used across AI/ML pipelines, data engineering, automation scripts, and backend APIs with FastAPI and Django. Python is our go-to for anything data-intensive or AI-driven.

React

Our frontend framework of choice for building fast, component-driven web applications. We build scalable UI architectures with React, TypeScript, and modern state management patterns.

React Native

React Native

Cross-platform mobile development without compromise. We deliver iOS and Android apps from a single codebase, with native performance and platform-specific optimizations where they matter.

Cloud & Infrastructure

We architect, deploy, and manage cloud-native infrastructure built for performance, resilience, and security from day one.

AWS

Amazon Web Services (AWS)

AWS is our primary cloud platform. We work deeply across EC2, ECS, EKS, Lambda, RDS, S3, CloudFront, VPC, IAM, and more — architecting solutions that are cost-efficient, secure, and production-proven.

Cloud Native

Cloud-Native Architecture

We design systems using cloud-native principles — containerization with Docker, orchestration with Kubernetes, service mesh, serverless patterns, and immutable infrastructure via Terraform and CloudFormation.

Nginx

Nginx

We configure and optimize Nginx as a high-performance web server, reverse proxy, and load balancer. This includes SSL/TLS termination, rate limiting, caching, and upstream failover for production-grade deployments.

Secured Cloud

Secured Cloud Setup

Security is built into every cloud environment we create — VPC isolation, IAM least-privilege policies, encrypted data at rest and in transit, WAF configuration, audit logging, and compliance-ready architecture (SOC 2, HIPAA-ready).

Databases & Data Storage

We select and architect databases based on scale, query patterns, and consistency needs — from relational OLTP to horizontally scalable NoSQL systems.

PostgreSQL / MySQL

PostgreSQL & MySQL

For structured data and complex relational workloads, we design normalized schemas, optimize query performance, manage migrations cleanly, and set up read replicas for high-availability systems.

Horizontally Scalable Databases

Horizontally Scalable Databases

For systems that need to scale beyond vertical limits, we work with MongoDB, DynamoDB, Apache Cassandra, and Redis. We architect sharding strategies, partition schemes, and caching layers that handle millions of operations per second.

AWS Managed Databases

AWS Managed Data Services

We leverage RDS, Aurora, DynamoDB, ElastiCache, and Redshift to reduce operational overhead while maintaining full control over performance tuning, backup policies, and disaster recovery configuration.

Data Architecture

Data Architecture & Pipelines

Beyond the database itself, we design data pipelines and event-driven architectures using Kafka, AWS Kinesis, and SQS to move data reliably at scale between services, storage, and analytics layers.

What We Deliver With This Stack

Technology knowledge is only valuable when it ships working products. Here's how we apply our expertise to real business outcomes.

Application Development

Application Development

End-to-end product engineering using Java, Python, React, and React Native. From architecture design and API development to UI build and production deployment — we own the full delivery lifecycle.

Application Modernization

Application Modernization

We migrate legacy monoliths to cloud-native microservices, re-platform on-premise applications to AWS, and modernize aging codebases to current Java or Python standards — with minimal disruption to running operations.

Secured Cloud Setup

Secured Cloud Setup

We provision and harden AWS environments from scratch — VPCs, subnets, security groups, IAM roles, encrypted storage, WAF rules, and compliance baselines configured before a single application workload goes live.

AI Development

We build production AI features using Python, LangChain, TensorFlow, and AWS SageMaker — from LLM-powered automation and NLP pipelines to predictive models and intelligent document processing at enterprise scale.

Maintenance & Support

Maintenance & Support

Post-launch support is part of how we work. We offer SLA-backed maintenance retainers covering bug resolution, dependency upgrades, security patching, performance monitoring, and on-call incident response.

Scalable Architecture

Scalable Architecture Design

We design horizontally scalable systems from the ground up — stateless services, distributed databases, event-driven communication, and Kubernetes-managed workloads that handle growth without redesign.
