Systems Architecture & Infrastructure

Custom Backend Development & API Systems

We engineer dependable server architectures, high-performance APIs, and robust relational database foundations designed to scale seamlessly without unexpected latency spikes or silent failures.

  • Sub-100ms p95 response latencies
  • Idempotent state mutation endpoints
  • 99.99% availability architectures
Core Capabilities

Infrastructure engineered to last

From monolithic refactoring to greenfield high-concurrency services, we build backends that handle serious business volume.

High-Throughput API Architecture

Modern REST and GraphQL services engineered with Python (FastAPI) or Go, featuring non-blocking concurrency and low p95 latency under high request loads.

Relational Database Design & Indexing

PostgreSQL schema optimization, composite indexing, partition strategies, and connection pooling via PgBouncer to eliminate N+1 bottlenecks.

Distributed Background Queues

Celery and Redis worker architectures with dead-letter queue (DLQ) guarantees, exponential retry policies, and idempotent mutation keys.

Observability & Telemetry

Integrated health checking, Prometheus metrics, structured JSON logging, and distributed tracing to detect anomalies before users notice.

Scope & Deliverables

Solid foundations for mission-critical software

Everything we deliver is fully tested, benchmarked under simulated load, and packaged with automated deployment scripts.

Modular API Services

Typed, documented OpenAPI specs with validation and clean service-layer abstractions.

Database Optimization Plan

Zero-downtime expand-contract schema migrations and tuned execution plans.

Resilient Queue System

Decoupled task workers handling asynchronous workloads with error boundaries.

Deployment & CI/CD

Dockerized microservices deployed to AWS, GCP, or bare metal with health monitoring.
