#MongoDB Stop running multiple queries when one aggregation pipeline does it all. $match → $group → $project in one round trip. Less network overhead. Less code. Faster results. MongoDB aggregation pipelines are one of its most powerful features. Use them. #MongoDB #Backend

#Kafka Kafka consumer groups are how you scale. One topic. Multiple consumers in a group. Each partition assigned to one consumer. Add consumers = add parallelism. Simple as that. 1/2

#Bedrock Building RAG? Don't build your own vector pipeline from scratch. AWS Bedrock Knowledge Bases handles chunking, embedding, and retrieval for you. Connect S3. Point at your docs. Done. You focus on the product. AWS handles the pipeline. #AWS #AI

#Freelance Write everything down. Scope. Deadlines. Deliverables. Edge cases. Verbal agreements don't exist in freelancing. If it's not in the contract, it didn't happen - and you'll be the one eating the cost. Protect yourself from the start. #Freelancing

#FastAPI FastAPI's Depends() is underused. Most devs use it for auth. That's it. But it's for anything: DB sessions, feature flags, rate limiters, request context. Clean. Testable. 1/2

AWS Lambda cold starts killing your response times? Provisioned concurrency is your fix. It keeps instances warm and ready. No init delay on critical paths. Don't apply it everywhere — it costs money. Apply it where latency actually matters. #AWS #Serverless

AIPrompt engineering is a real skill. Treat it like one. Most devs write one prompt, get a bad output, blame the model. The model is fine. Prompt is the problem. Be specific. Give examples. Define the format. Output quality = prompt quality. Invest in it. #AI #LLM

Always get 50% upfront. Not because clients are bad. Because scope shifts, priorities change, and your time is real. No deposit = no start. Non-negotiable. The right clients won't blink. 1/2

@Transactional propagation levels are one of those things most Spring Boot devs never fully understand. REQUIRED joins an existing transaction or creates one. REQUIRES_NEW always starts fresh — even rolls back independently. NESTED creates a savepoint inside the current one. 1/2
