Your backend directly impacts user experience, even if your users never see it.
Slow page loads, laggy buttons, or delayed data refreshes? That’s usually not the frontend, always it’s the backend.
At TLVTech, we work with startups and scaleups that need their products to feel fast, responsive, and stable. Here’s a breakdown of the backend optimization techniques we use to reduce latency and deliver a smoother UX.
Not everything needs to hit the database.
Where we apply it:
Tools we use:
Redis, Cloudflare Cache, in-memory caches for local performance.
Tip: Set smart expiration times and invalidate carefully—stale data is often worse than slow data.
We see this too often: slow APIs caused by N+1 queries, unindexed fields, or lazy joins.
What we do:
EXPLAIN ANALYZE)ORMs are useful—but dangerous when misused. We regularly inspect and optimize what they generate.
If a user doesn't need to wait for it, don’t block the request.
Offload to background jobs:
Tools we use:
BullMQ, Celery, AWS SQS, Cloud Tasks.
This frees up your API to respond fast and keeps your frontend smooth.
Every extra call across microservices or 3rd-party APIs adds latency.
How we solve this:
Your architecture should be lean—not just “micro.”
Large payloads = slow UX. Especially on mobile or bad connections.
Tips:
Small responses = fast interfaces.
You can’t optimize what you don’t track.
What we track:
Tools we use:
Datadog, Prometheus + Grafana, Sentry, and OpenTelemetry.
Every project at TLVTech launches with observability baked in.
When we talk about UX, we usually mean design, animations, or responsiveness.
But nothing kills UX faster than a slow or flaky backend.
At TLVTech, we build backends that feel fast to users—even under load. If your product needs to deliver performance and scale without technical debt, let’s talk.

- gRPC is a high-speed, open-source system created by Google, used for service joining and data transfer using HTTP/2. - gRPC's architecture focuses on breaking down big problems into small ones for easy, efficient resolution. - It uses Protocol Buffers (Protobufs) for data format, which set rules for data and convert the rules into code. - Compared to REST APIs, gRPC is more efficient due to its use of HTTP/2 and Protobufs, but REST is simpler and lighter. - gRPC supports video streaming with its bi-directional ability and can be paired with multiple languages like C# or GoLang. - gRPC can be integrated easily with Python and Java, requiring installation of libraries and the creation of a .proto file. - According to online community discussions, gRPC, REST, WebSockets, and GraphQL each have their uses and strengths depending on the project's requirements. - gRPC is beneficial for microservices over Kafka due to its data serialization and deserialization capabilities. It can be used with Spring Boot or C# for creating microservices.
