Microservices Architecture & AWS
A system that handles the peak without going down and without costing a fortune when idle. Architecture chosen by measured trade-offs, not trends.
When the monolith can no longer keep up
Every successful system reaches a point where growing hurts: one deploy takes everything down, a heavy job locks the whole database, and the cloud bill grows faster than revenue. Microservices are not the automatic answer — misapplied, they trade one problem for several. The right question is which part needs to scale on its own, and that is where I start.
What is included
-
Assessment before proposal
Where the real bottleneck is, measured. Many things that seem to require a rewrite are solved with an index and a cache.
-
Split along real boundaries
Services divided by business domain, not technical layer. Versioned contracts between them.
-
Messaging and async processing
RabbitMQ to decouple what does not need to be synchronous, with retry policies and dead-letter queues.
-
AWS infrastructure
Docker containers, zero-downtime deploys and sizing based on real cost.
-
Load testing with k6
Find the limit in a test environment, not on Black Friday.
-
Incremental migration
Without stopping the product. Route by route, with the option to roll back at any moment.
Why work with me
I have worked with microservices in production for years: containers, asynchronous messaging, service-to-service communication over gRPC and cloud infrastructure with load testing. Much of it on financial platforms, where failure is not an option because users’ money is involved — and that level of demand shapes how I design systems.
Frequently asked questions
Do I really need microservices?
Probably not, and that is the honest answer in most cases. A well-organized monolith handles far more than people imagine. I say this before selling a project, because the wrong architecture costs dearly for years.
Can we migrate without stopping the system?
Yes, and that is how I do it. A gateway routes specific paths to the new services while the current system keeps serving the rest.
What about AWS costs?
Sizing is part of the project. The bill often drops after migration, because what was oversized starts scaling on demand.
Do you take over operations afterwards?
I can deliver with a runbook and train your team, or keep providing support. Both work.
Can you work embedded in our team?
Yes. Outsourcing as a senior full stack Node.js and React engineer is one of the formats I offer.
