High-Performance DeFi & DEX Infrastructure

Our Client’s Backstory

Our client is a Silicon Valley Web3 R&D laboratory specializing in decentralized finance (DeFi) and data protocols. As a developer for blockchain indexing systems, they launched a high-performance decentralized exchange (DEX) aggregator designed to optimize cryptocurrency swaps across liquidity sources. Utilizing a Smart Order Routing (SOR) algorithm, the platform supports multi-token swaps across blockchain networks. To support their growth, the client required a technical partner to harden their infrastructure and transition their platform into an enterprise-ready DeFi utility.



The Challenges

Maintaining a trading environment in the Web3 space required overcoming architectural and operational bottlenecks. Key challenges included:

  • Infrastructure Fragmentation: Migrating a distributed, serverless environment from GCP to AWS to align with enterprise scalability and security goals.

  • Latency Requirements: Handling volatile DeFi traffic with an API design capable of managing rate limiting and abuse prevention without sacrificing speed.

  • Scalability Bottlenecks: Transitioning from serverless functions to a containerized microservices architecture capable of supporting high-throughput trading volumes.

  • Operational Complexity: Managing continuous deployment, monitoring, and Infrastructure-as-Code (IaC) requirements for a Web3 product with a research-heavy internal team.


The Solution

Klika deployed an engineering squad to provide the architectural oversight and implementation capacity needed to scale the platform. Our solution included:

Cloud Infrastructure Modernization

Spearheaded the migration of the microservices estate to a fully managed AWS environment using Terraform, ensuring 100% reproducible deployments.

High-Throughput API Engineering

Implemented an API layer utilizing FastAPI, featuring rate-limiting and anti-abuse mechanisms to ensure resilience against bot traffic.

Containerized Microservices Ecosystem

Transitioned backend services to a hybrid containerized model using AWS ECS Fargate and Lambda, enabling dynamic resource allocation.

End-to-End Observability Suite

Designed and deployed a logging and monitoring framework to provide visibility into service health and trade execution latency.

Full-Stack Feature Integration

Bridged the gap between algorithm execution and the user-facing React frontend, delivering enterprise-grade features for the DeFi community.

Automated CI/CD Workflows

Engineered deployment pipelines using GitHub Actions to eliminate configuration risks and accelerate the release cycle.
