Small update 👋 I’m merging the communities. BackendInProd FounderInProd → The 1% Engineers Reason: real systems aren’t just backend anymore. Founders, developers, and SaaS builders are all solving the same Problems: • scaling systems • production failures • AI infrastructure • system design • real trade-offs Instead of splitting discussions across communities, we’ll build one strong place for serious builders. If you’re a developer, founder, or SaaS builder working on real products, join the community and start the conversation. Let’s build smarter systems together.

Welcome to BackendInProd 👋 This is a space for backend engineers and builders shipping real production systems — migrations, auth, scaling, failures, and the trade-offs behind them. But we’re expanding the lens: ➡️ Not just backend ➡️ Not just APIs ➡️ But the AI infrastructure behind the scenes Because modern systems aren’t just CRUD anymore. They include: • model serving pipelines • vector search & retrieval • streaming queues • caching & latency games • cost vs accuracy trade-offs • and the messy reality of running AI in prod This community is about documenting what actually happens in production. No toy examples. No highlight reels. Just honest lessons from building and fixing real systems. Feel free to share: • What you’re working on • What broke • What you’re trying to understand • What AI/backend challenge you're facing Let’s learn in public and build calm, reliable systems together. Connect with me — we’re going deep into AI Backend in prod. 🚀 #BackendInProd #AIInfrastructure #BuildInPublic twitter.com/i/communities/20…

BackendInProd has been quiet lately 🤔 Let's fix that. If you're building something -> share it. If something broke -> share it. If you learned something the hard way -> share it. This community exists because we grow faster together than alone. But that only works if we actually show up and share. Real talk: I've been quiet too. Let me restart: This week I'm: • Refactoring notification service (currently a mess) • Fighting with Kafka consumer lag • Trying to optimize a 3-second query Not perfect. Not polished. Just real work. Your turn 👇 What's one thing you're working on RIGHT NOW? Don't overthink it. Just drop it below. Let's get BackendInProd active again. #BackendInProd #BuildInPublic

The Engineering Trade-off (FastAPI vs. Spring Boot) We just started migrating a core service from FastAPI to Spring Boot Microservices. I love Python. It’s the king of speed-to-market. But at a certain scale, the conversation shifts from "how fast can we write it?" to "how well does it sustain?" Why we are shifting: Strict Typing: Runtime errors in production are expensive. Java’s compile-time safety catches bugs before deployment. Ecosystem: Spring Cloud, Actuator, and Resilience4j give us "production-ready" features out of the box that we were rebuilding manually in Python. Concurrency: Virtual Threads (Project Loom) are changing the game for I/O heavy workloads. Python got us from 0 to 1. Java is taking us from 1 to 10.

One of the biggest backend mistakes I made early: Designing systems for how they should work, not for how they fail. In production: networks drop retries pile up queues back up databases slow down under real load Good system design isn’t about clean diagrams. It’s about answering the uncomfortable questions: - What breaks first? - What happens at 10× traffic? - What happens when one dependency lies? The best architectures I’ve seen were boring: - simple flows - clear ownership - graceful failure paths Production doesn’t reward cleverness. It rewards predictability. Design for failure. Everything else is optimism. What’s one failure assumption you fixed that changed your design approach? Drop it below 👇 #BackendInProd #Backend #SystemDesign #MyBackendJourney

Last week: Finished the architecture flow for my first SaaS. This week: Designed and coded the landing page. And honestly, frontend design is… annoying 😅 Spacing, colors, responsiveness, alignment, nothing ever feels “done”. But as a backend engineer, this part matters more than I thought. Because: architecture sells after the landing page systems matter after someone signs up good backend with bad UX = invisible product So yeah, struggling through frontend. Not because I love it, because shipping a SaaS means owning the whole flow. Back to tweaking pixels. Then back to APIs. That’s the game. #BackendInProd #SystemDesign #DevCommunity #TechTwitter

BackendInProd is for people who live in production, not just talk about it. This space is for backend engineers and tech builders who: • Debug prod at 3 AM • Fight migrations and scaling pain • Draw real system diagrams from scars • Share failures that actually hurt (and the fixes that worked) No toy examples. No highlight reels. No fake hustle. Just honest lessons from building and fixing systems that survive (or break spectacularly). If you're deep in real backend work stay. If you know someone quietly grinding prod, invite them. What are you currently breaking or fixing in prod? One-liner welcome. Let's build better systems together. #BackendInProd #MyBackendJourney #BackendEngineering #SystemDesign #RealEngineering

Real backend isn’t just clean async code or fancy queues it’s surviving prod chaos and still shipping reliably. Shared what actually moved the needle after months of breaking & fixing things at scale. Read the full article here 👇 #BackendInProd #SystemDesign #ProductionEngineering

Retries don’t fix failures. They amplify them. One slow downstream → retry → more load → slower → retry → overload. Exponential damage. This diagram shows why retries are dangerous and why DLQ isolation is the real fix 👇 Backend builders, your worst retry amplification story? Share below 👇 #Backend #SystemDesign #BackendInProd

Done for the day. It’s past midnight. Docs closed. Logs quiet. Another day of backend trade-offs, small fixes, and decisions that won’t show immediately. Shipping is rarely loud. Most of it happens like this. Time to shut it down. #MyBackendJourney #BackendInProd

Backend failures are rarely instant. They accumulate quietly. Logs usually tell the story late. What surfaced it for you? #BackendInProd #DevLife #SoftwareEngineering

Quick insight. Most backend issues aren’t hard because the code is complex. They’re hard because the real cause is hidden behind bad logs, wrong assumptions, or generic errors. Fixing prod is less about writing code and more about seeing clearly. #BackendInProd #MyBackendJourney

I break down backend systems the way they behave in production. What you’ll find here: • System design (real-world, not theory) • Architecture diagrams & trade-offs • Failures, mistakes, and prod lessons If you’re a backend engineer who wants to think like an owner — follow. #BackendInProd

Async vs Event-Driven is not a style choice. It’s a failure-mode decision. Async: Shared resources, fast path but one slow task starves all. Event-Driven: Decoupled queues, backpressure survives spikes better. This diagram shows why 👇 Still learning the trade-offs in prod. which do you lean on for high-traffic systems, and why?👇 #Backend #SystemDesign #BackendInProd

#BuildInPublic Monday done and dusted from Delhi, India 🇮🇳 Quiet but solid day on the backend grind: • Kicked off discussion on system design: async vs event-driven architecture (still thinking through trade-offs) • Finally got Kafka setup running tested producers and consumers end-to-end • Fixed a few sneaky bugs that were hiding in plain sight • BackendInProd community grew from 0 → 27 members (thank you for joining the real prod talks) • Launched new one: FoundersInProd for serious builders shipping MVPs, SaaS, or any tech product from scratch. Execution over ideas. No big spikes, just steady commits. Thank you all for being part of this journey the likes, replies, and shares mean a lot. If any of these prod stories or diagrams helped you today, keep sharing, building, and growing together 🚀 Tomorrow's another day to ship.

Good morning everyone ☕ Quick update: BackendInProd community now at 10 members thank you for joining the discussions on real production systems. Growing nicely! How was your weekend restful break, deep coding sessions, or time with family/friends? And what's on your plan for the week ahead feature ships, refactors, or tackling tough bugs? Looking forward to more real engineering conversations: building products that handle scale, migrations, auth challenges, and everything that survives production. Let's learn and level up together. Share your updates below! #BackendInProd #BackendEngineering #SystemDesign #MyBackendJourney

I’ve started a community called BackendInProd. It’s for backend engineers and tech builders who want to talk about real production systems migrations, auth issues, scaling, failures, and the trade-offs behind them. If you’re building or maintaining backend in the real world and learning in public, you’re welcome to join. #BackendInProd #MyBackendJourney twitter.com/i/communities/20…
