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.
