Production / Reliable / Cost-Efficient

AI Infrastructure& High-Concurrency Backends

Production-ready backends for B2B SaaS and logistics platforms. We specialize in RAG, real-time systems, and cloud-native architecture.

Solutions

Modular capabilities designed to deliver measurable outcomes with clear scope and accountability.

AI Infrastructure & RAG Systems

Production-grade retrieval and LLM systems, from prototype to scale. We specialize in hybrid search, vector databases, and cost-optimized inference. Tech: Java, Spring Boot, Milvus, Redis, AWS. Typical outcomes: sub-second query latency, 70%+ reduction in manual support workload.

High-Concurrency Backend Systems

Real-time services and event-driven platforms built for scale. Expertise in caching, messaging, and distributed rate limiting. Tech: Redis, Kafka, RocketMQ, PostgreSQL. Typical outcomes: 10k+ RPS sustained throughput, 99.9%+ availability, millisecond-level response.

Cloud & DevOps

Cloud-native architecture and automation to improve reliability and deployment velocity. CI/CD, Infrastructure as Code, zero-downtime migrations. Tech: AWS, Docker, Terraform. Typical outcomes: reduced deployment time from days to minutes, infrastructure cost optimization.

Case Studies

Representative engagements demonstrating our approach to backend and AI delivery. Client details anonymized under NDA.

B2B SaaS / AI Customer Support

Intelligent Support Automation for High-Volume SaaS

A Canadian B2B software company faced rising support costs as its user base scaled.

Challenge

Customer inquiries were growing faster than support headcount. Legacy FAQ and ticket systems couldn't handle multi-turn questions, leading to long wait times and inconsistent answers.

Solution

Codary Labs designed a multi-stage RAG system with intent routing, hybrid retrieval, and cost-aware LLM orchestration. Implemented guardrails for reliability, rate limiting, and multi-model fallback. Java + Spring Boot + AWS architecture.

Results

Sub-second response latency for complex queries
Significant reduction in manual ticket triage and support workload
LLM inference cost controls enforced per tenant
High availability maintained during third-party model outages
Deployed from prototype to production in under one quarter

How we work

No slide decks. Just working software, fast.

We keep delivery simple with clear scope and accountability. Our approach for backend and AI systems:

1) Align in 1 week

Kickoff to lock scope, tech stack, and success metrics. We define target latency, cost budgets, and launch dates upfront. No endless requirements docs.

1) Align in 1 week

2) Ship every 2 weeks

Build in Java + Spring Boot + AWS. You get a working demo every sprint. Code in GitHub, infrastructure as code with Terraform, CI/CD from day one.

2) Ship every 2 weeks

3) Measure in production

We set up monitoring for latency, cost, and uptime before launch. You own all code, data, and cloud accounts. We stay on for optimization post-launch.

3) Measure in production

From kickoff to production: typically 8-12 weeks for initial release.
