Backend & systems engineering

Bulletproof backends. Practical AI.

We design, rebuild, and stabilize the mission-critical systems that keep businesses online—without account managers, mystery, or AI vaporware.

01When teams call us

Your backend should not be the thing holding growth back.

Hakkil works with product teams that have outgrown fragile infrastructure, slow databases, manual deployments, and opaque production systems.

01

Traffic became an incident

An MVP is now a real business, but timeouts, queue pressure, and resource spikes appear whenever demand rises.

02

The monolith cannot move

Profitable legacy software is slowed by lock contention, old frameworks, and risky all-or-nothing releases.

03

Production is a black box

Logs, metrics, and traces are disconnected, leaving teams to investigate failures after customers report them.

04

AI reached production unguarded

LLM costs, sensitive data, fallbacks, and provider failures need systems engineering—not another demo wrapper.

Five ways we remove the bottleneck.

Direct access to the engineers
01

High-performance Go systems

Concurrent services, clean REST and gRPC APIs, transactional PostgreSQL, and lightweight server-rendered applications.

02

Legacy and database modernization

Incremental PHP modernization, query-plan analysis, safe service extraction, caching, and framework upgrades.

03

DevOps and infrastructure

Boring deployments through CI/CD, secure containers, Kubernetes, Terraform, backups, and repeatable environments.

04

Observability without blind spots

Correlated metrics, structured logs, distributed traces, dashboards, SLOs, and alerts people can act on.

Practical AI integration

RAG data pipelines, cost-aware LLM middleware, privacy controls, provider fallbacks, and local inference.
