Learning objectives

  • Master advanced concurrency patterns with goroutines and mutexes
  • Optimize performance using native profiling and benchmarking
  • Develop resilient microservices with gRPC and Protocol Buffers
  • Implement distributed tests and fuzzing for maximum robustness
  • Deploy Go applications in Kubernetes with Helm and operators
  • Manage errors and telemetry with OpenTelemetry
  • Build scalable high-availability APIs

The Learni story

Founded by passionate learning and innovation experts, Learni's mission is to make professional training accessible to everyone, anywhere in the world. Our team operates in major hubs — London, New York, Boston — and internationally, to support talents and organizations in upskilling.

Don't let this gap widen

Why this program matters

  • Without expert Go mastery, your applications suffer concurrency bottlenecks, causing 40% more latency under load, as observed in 70% of legacy backend teams.

  • Risk of critical downtimes at 25% in production due to undetected race conditions, leading to estimated client losses of 50k€/incident.

  • Lack of performance tuning exposes you to inflated cloud costs x3, with urgent refactoring under pressure.

  • Stay stuck on obsolete stacks while Go competitors scale to millions of users.

  • Invest now to avoid 200 hours of useless debugging and boost ROI x5.

Program

Module 1Advanced Concurrency: Goroutines, Channels, and Sync (Go stdlib)

Dive into the deep mechanics of Go concurrency, implementing optimized worker pools, non-blocking selects, and conditional mutexes during hands-on workshops on real high-load cases, to produce immediately thread-safe prototypes, and feel the power of a Go that scales without limits.

Module 2Performance Tuning: pprof, Race Detector, and Zero Allocation

Analyze and fine-tune your Go binaries with built-in pprof and trace tools, benchmarking critical algorithms, hunting memory leaks through hands-on exercises on massive datasets, and generating actionable performance reports, transform your apps into ultra-responsive machines ready for prime time.

Module 3Go Microservices: gRPC, Envoy, and Service Mesh

Build interconnected microservices with gRPC and Protocol Buffers, integrate Istio for traffic management during distributed simulations, deploy resilient sidecars via collaborative challenges, and deliver a functional cluster that withstands failures, become the architect of infallible systems.

Module 4Expert Testing: Table-Driven, Fuzzing, and Property-Based

Push Go tests to the extreme with go test -race, native fuzzing, and testify, covering 100% of edge cases on concrete projects like HTTP parsers, debug live with delve, produce bulletproof CI/CD test suites, ensure code quality that impresses your peers.

Module 5Professional Deployment: Kubernetes, Helm, and Observability

Orchestrate your Go apps in K8s with custom operators and Helm charts, integrate Prometheus/Grafana for real-time monitoring, simulate zero-downtime deployments on minikube, finalize with a deliverable capstone project for production, leave with complete expertise to scale globally.

Evaluation method

  • Daily technical quizzes, graded practical exercises, final deployed microservice project, Qualiopi-recognized certification.

Learning method

  • 80% hands-on workshops, pair coding challenges, individualized expert feedback, Fortune 500 case studies.

Methods, materials and delivery

The Training Go Expert - Optimize Scalability and Performance program is delivered onsite or remote (blended-learning, e-learning, virtual classroom, remote presence). At Learni, an industry-certified training organization, every program is built to maximize skills acquisition regardless of the chosen format.

The trainer alternates between demonstrative, interrogative and active methods (through hands-on labs and/or scenarios). This pedagogical approach guarantees concrete learning that's immediately applicable at work.

Equipment required

For the smooth delivery of the Training Go Expert - Optimize Scalability and Performance program, the following equipment is required:

  • Mac or PC computers, high-speed fiber internet, whiteboard or flipchart, projector or interactive touch screen (for remote sessions)
  • Training environments installed on workstations or accessible online
  • Course materials, hands-on exercises and complementary resources
  • Post-training access to materials and educational resources

For intra-company training on a site outside Learni, the client commits to providing all required teaching materials (computers, internet, etc.) for the smooth delivery of the program in line with the prerequisites in the communicated program.

* contact us for remote delivery feasibility** ratio varies depending on the program

Skills assessment methods

Assessment of skills acquired during the Training Go Expert - Optimize Scalability and Performance program is performed through:

  • During training: case studies, hands-on labs and professional scenarios
  • End of training: self-assessment questionnaire and skills evaluation by the trainer
  • After training: completion certificate detailing acquired skills

Program accessibility

Learni is committed to making its programs accessible. All our programs are accessible to people with disabilities. Our teams are available to adapt the pedagogical methods to your specific needs. Please contact us for any adjustment request.

Enrollment terms and lead times

Learni programs are available inter-company and intra-company, onsite or remote. Enrollments are possible up to 48 business hours before the program starts. Our programs are eligible for corporate funding paths. Contact us to discuss your training project and funding options.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

  • Triple validation: technical, pedagogical, sectoral.
  • Minimum rating 4.8/5 over the last 12 sessions.
Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

  • Live briefing on goals and team context.
  • Veto right — we swap the trainer for free if needed.
Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

  • Hands-on cases drawn from your stack and projects.
  • Program co-written then validated by your team.
Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

  • NPS, knowledge quizzes and skills self-assessment.
  • Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
