Critical backend, performance, and legacy modernization

Is your system slow, unstable,or hard to scale?

Codifica steps in when production starts to drag: heavy queries, slow reports, broken queues, failing jobs, brittle APIs, and legacy systems blocking change. We modernize systems without interrupting operations.

Services

Work structured around problem, solution, and operational impact

We step in to resolve production bottlenecks: heavy databases, fragile APIs, unstable queues, slow reports, and legacy that is hard to evolve.

Diagnosis & Audit

We map bottlenecks across database, APIs, queues, cron, integrations, and architecture to prioritize what is blocking operations and growth.

  • Architecture, code, and critical-flow audit
  • Query, job, queue, and cron analysis
  • Technical plan with priorities, risk, and impact

Performance & Reporting

We fix latency where it becomes expensive: heavy queries, slow reports, overloaded APIs, and processing that cannot keep up with the business.

  • SQL, indexes, and critical-read optimization
  • Faster APIs, dashboards, and report generation
  • Cache, concurrency, and async processing review

Legacy Modernization

We modernize systems without interrupting operations, reducing coupling, technical debt, and change risk in critical environments.

  • Backend legacy, monoliths, and aging integrations
  • Gradual migration of database, services, and contracts
  • More predictable, testable, maintainable code

Reliability & Operations

We stabilize the layer that keeps the business running: queues, jobs, cron, integrations, observability, and cloud operations.

  • Failure handling and safe reprocessing
  • Monitoring, alerting, and traceability
  • Scale with fewer incidents and less improvisation

Proof / Results

We turn fragile systems into scalable operations.

We work where slowness and instability translate into lost revenue, rework, reactive support, and growth risk.

Reports and queries stop blocking operations

We rewrite queries, indexes, and critical pipelines to cut response times, relieve database pressure, and restore predictability.

Queues, jobs, and cron become predictable again

We address silent failures, concurrency, and reprocessing to stabilize critical tasks and reduce peak-time bottlenecks.

Scale without breaking production

We tune backend, database, cache, cloud, and observability to support growth with fewer incidents and less degradation.

Cases

Production problems we solved

Examples of operations that required performance, reliability, and safer evolution.

Performance
300k users

Incentive platform with critical operations

Problem

Database and backend were under pressure from campaign rules, reporting, and continuous operations.

Intervention

We restructured queries, processing, and backend organization to remove critical bottlenecks.

Impact

The platform handled high volume with more predictability and less degradation.

Geo data
Reliable history

Geolocation service with reliable history

Problem

Events and geospatial persistence needed consistency to avoid breaking integrations and traceability.

Intervention

We stabilized mutations, events, and geographic storage with a more predictable production flow.

Impact

Automated history became trustworthy and location-driven integrations became more reliable.

Legacy
No-downtime migration

Oracle to Postgres legacy modernization

Problem

The legacy stack was costly to maintain and slowing down change in sensitive business flows.

Intervention

We migrated data and services gradually while keeping operations running.

Impact

Lower operational cost, simpler maintenance, and real performance gains.

APIs
Stable integration

APIs and integrations with fewer failures and less rework

Problem

Fragile contracts and cross-system failures were creating recurring operational rework.

Intervention

We reorganized contracts, error handling, and async processing across critical flows.

Impact

More predictable integrations, fewer chained failures, and less reactive support.

Operations
Spreadsheet -> Backend

Spreadsheet-driven operations moved into backend workflows

Problem

Too much manual control, low traceability, and constant team intervention.

Intervention

We turned fragile flows into systemized, traceable backend processes.

Impact

Less operational improvisation and a stronger base for scaling beyond spreadsheets.

Field ops
Validated geofence

Geographic validation for field operations

Problem

Execution in the correct location had to be validated without relying only on manual checks.

Intervention

We built a geofence layer with async processing for automatic validation.

Impact

Less operational error and more trust in distributed field operations.

About

Senior engineering for systems already running in production

We operate internationally with a distributed team across Europe and Latin America. Codifica is positioned to fix, optimize, and scale critical systems with technical clarity and safe execution.

Hands-on experience in backend, performance, databases, queues, APIs, cloud, and legacy modernization.

Direct production work focused on operational stability, maintainability, and scale without improvisation.

We step in to fix problematic systems and leave behind an operation that is more predictable, reliable, and ready to grow.
