Backend engineering · Cloud · Architecture
Production software, built with judgment.
PRN Tech designs, builds and operates backend systems for companies that depend on them every day — with senior-level technical depth and the accountability of someone who also operates what they ship.
Senior, direct
The person who designs is the person who builds. No layers between decision and code.
Production first
Every system is born observable, tested and ready to operate — not merely delivered.
Explicit tradeoffs
Consistency, latency, cost and operations discussed openly — before they become debt.
Services
Three ways of working together.
Backend & cloud engineering
Building APIs, services and data pipelines in Go, Python and TypeScript on AWS — from first commit to operations.
- REST & gRPC APIs
- Event-driven architectures
- Integrations & migrations
Systems architecture
Architecture design and review with formally recorded decisions — to grow without scale or cost surprises.
- Design reviews & ADRs
- Data modeling
- AWS cost optimization
Consulting & advisory
A senior engineer alongside your team: unblocking decisions, reviewing critical code, raising the engineering bar.
- Critical code review
- Application security (AppSec)
- Technical mentoring
- Technical due diligence
Capabilities
A toolset chosen with the same judgment.
Selected work
Systems in production, not presentations.
A sample of recent engagements. Details protected under NDA.
Real-time notifications at the scale of millions
Push-notification service in Go for a sports platform — gRPC and AWS SNS processing millions of events per day.
Python to Go, zero downtime
Incremental migration of a production REST API using the Strangler Fig pattern — endpoint by endpoint, no maintenance window.
Event sourcing & CQRS in production
Designing and operating event-driven architectures — consistency, hidden operational costs, and migrating shared databases across microservices.
Recurring-billing platform
Go APIs, payment reconciliation and banking integrations for daily operation without manual intervention.
Fleet event pipeline
Telemetry ingestion and aggregation on AWS — queues, workers and PostgreSQL consolidation.
Architecture review & scaling plan
Database bottleneck diagnosis, caching strategy and cost projection for a fast-growing SaaS.
