💡As a backend engineer, it's really important to think about how to make our API responses as fast and efficient as possible. It's our job to ensure we deliver high-quality products and outputs to our clients. To achieve this, there are several key areas we need to focus on: ✅ Database design ✅ Proper indexing ✅ Normalization/denormalization ✅ Partitioning ✅ Caching ✅ Query optimization If you have any additional points, please feel free to add them below.

What Should Backend Engineer DO? The backend engineer role is pivotal in software development, responsible for creating and optimizing the server-side systems that support web and mobile applications. Backend engineers ensure that applications are scalable, secure, and efficient, handling critical components such as databases, APIs, and infrastructure design. It requires expertise in system architecture, database management, API development, and security. This position is highly technical and demands the ability to solve complex problems, optimize performance, and build scalable solutions. Backend engineers are essential to delivering robust, reliable systems that drive the functionality and success of modern applications. Main Aspects of the Role: 1.System Architecture & Scalability: Design backend systems that can handle growing user demand, ensuring high availability, performance, and scalability. 2.API Development: Build and maintain secure, efficient APIs that enable seamless communication between frontend systems and backend services. 3.Database Management: Develop and optimize relational (e.g., MySQL, PostgreSQL) and NoSQL (e.g., MongoDB) databases to ensure efficient data storage and retrieval. 4.Security & Data Integrity: Implement strong security measures, including encryption and authentication protocols, to protect sensitive data and maintain system integrity. 5.Performance Optimization: Improve the speed and efficiency of backend processes by fine-tuning code, caching mechanisms, and optimizing server performance. 6.Collaboration: Work closely with frontend developers, product managers, and other teams to ensure backend systems meet the needs of the overall project.

KISS and show some love for PostgreSQL 💋 Do you really need the operational complexity that comes with deploying multiple database solutions? PostgreSQL is every kind of database and it’s transactional. 📄 Document: Built-in JSON and JSONB data types. 🔍 Vector: pgvector extension (semantic/similarity search for ML applications). 🌐 Graph: (Apache AGE extension - supports Cypher queries). 🔎 Search: pg_bm25 extension (tf-idf like elastic search). 📑 Columnar: Citus extension. 🔑 Key-value cache: Unlogged tables (it’s not Redis but it could work - measure it!). 🔗 Relational: doh. Solve first, optimize later: PostgreSQL is a pragmatic solution to get started with. The problem you actually have may not be the one you would like to have; those millions of customers may never show up! Do you know someone who is looking for a pragmatic senior engineer? I am currently looking for a Java, Kotlin, Typescript or Rust role. AWS, Google Cloud, Kubernetes etc. Yes - I also do PostgreSQL. Bristol and/or remote. Please feel free to message me, like or repost.

Position: MidLevel Golang Developer Location: Plano, TX (3 days onsite/week)   Duration: 6 Months+ Face2Fave Interview – Need local to Plano/Dallas  PAY RATE: $60/HR ON C2C Must Have: 3+ years of experience Monitoring experience (i.e. Datadog, Prometheus or other) Golang (Channels, Go Routines) Microservices Event driven architecture experience such as Kafka, Kinesis or other Docker / Kubernetes preferred Testing Nice to Have: Protobuf Go event architecture AWS – ECS, Beanstalk Responsibilities.   Develop new features. GoLang (Not as concerned on the version. If they can explain they have worked with concurrency in GO. Channels, Go Routines, is a strong signal of right fit. Library wise. If they have worked with protobufs that would be nice. If they have done GO event architecture would be nice.) They run in Kubernetes cluster. If they have worked with AWS ECS or Beanstalk or AWS Services in general would be nice to have but not required. AWS is more devops and not too important for them to have. Docker for containerization is used here. Testing - Just what you would expect from a dev perspective. Distributed Systems (Microservices), debug issues, root cause analysis.  Dealing with Microservices that talk to 3rd party Observability – Datadog (Log Files, tracing, monitoring) – Don’t need to have specific Datadog experience. Monitoring experience in a Microservices environment would do with a comparable tool. Understand difference between logs and metrics. (Have you setup Promethus metrics? For example) Multiple different Microservices (understand the traceability, debug). SK SAHID HUSSAIN.

Hey everyone, 👋 I'm Doron, a Backend Engineer. Today, I want to talk about Handling Database Migrations in Production. Deploying new features often means updating your database schema, but doing so in a live production environment can be risky. You don’t want to cause downtime or break existing functionality. Here’s how I handle database migrations seamlessly without disrupting the user experience: 1. Non-blocking Schema Changes Using a tool like gh-ost, I can perform non-blocking schema changes in MySQL. It creates a shadow table and migrates data without locking your production tables, keeping your system online while changes are made. 2. Backward-Compatible Code With Flyway, I version my database schema and ensure that the code supports both the old and new schema before fully migrating. This avoids breaking functionality if some parts of your system still rely on the old structure. 3. Feature Flags for Safe Rollouts Feature flagging tools like LaunchDarkly allow me to toggle between old and new features that rely on different schema versions. This lets me safely test changes and revert back quickly if needed, without affecting the database itself. 4. Phased Schema Updates Instead of doing all updates at once, tools like Sqitch let me roll out incremental changes. First, I add a new column, then deploy the app changes that write to it, and finally remove the old column once everything is stable—this minimizes risks. 5. Testing & Rollback Plans Before applying migrations in production, I simulate changes using TestContainers in a staging environment with production-like data. Having rollback plans ready, like snapshots or reverse migrations, is critical in case something goes wrong. By following these steps and using the right tools, you can handle database migrations in production with confidence and avoid downtime. How do you handle migrations in your projects?
