Pomai Ecosystem - AI-Driven Observability: How I Built a 1M+ Log Analysis Pipeline on a Budget
When my system logs hit the million-mark, human inspection became impossible. Here is how I turned raw logs into actionable intelligence using RAG, Kafka, and CPU-only AI.
Pomai Ecosystem - The AI Reality Check: Why I Chose Qwen2.5 0.5B and Ditched Heavy Frameworks
When building an AI-native SaaS, it is easy to get caught up in the hype of massive models and complex frameworks. Here is why I went the opposite direction: a tiny 0.5B model and raw Python.
Pomai Ecosystem - From Port-Hell to High Availability: Architecting an Enterprise-Grade API Gateway
When my microservices multiplied, managing routing and security became a nightmare. Here is how I evolved from a custom-coded proxy to a Highly Available Kong and Nginx Gateway cluster.
Pomai Ecosystem - When One Service Falls, They All Shouldn't: Building Resilience with Circuit Breakers and Retry Logic
In a distributed system, a single service failure can cascade through the entire ecosystem. Here is how I learned that circuit breakers alone weren't enough and why retry logic with exponential backoff became essential for keeping Pomai Ecosystem alive during network hiccups.
Pomai Ecosystem - The Dual-Write Dilemma: Ensuring Data Integrity in a Distributed Ecosystem
Splitting a monolith into microservices is easy. Keeping the data consistent across them is the real nightmare. Here is how I solved the dual-write problem using the Transactional Outbox Pattern and Kafka.
Pomai Ecosystem - The 3-Pillar Architecture: Decoupling Real-time Data, Analytics, and AI
How I architected a highly scalable, polyglot microservices ecosystem by decoupling data ingestion, stream processing, and AI reasoning into three resilient pillars.
Pomai Ecosystem - The Polyglot Contract: Taming Microservices Chaos with Protobuf
How a single JSON typo crashed my data pipeline, and why I migrated my entire Go, Python, and Node.js ecosystem to Protocol Buffers.
Pomai Ecosystem - From a Multi-Module Monolith to a Microservices Architecture`
Pomai Ecosystem did not begin as a microservices platform. Like many personal projects, it started with a single frontend application connected to a backend organized as a multi-module monolith. Every feature lived inside the same repository and shared the same Firebase Firestore database. Modules communicated through direct imports or internal REST endpoints while remaining deployed as one application.
Pomai Ecosystem - Taking Back Control: Why I Built a Self-Hosted CI/CD Pipeline for My Microservices
Moving to microservices solved my scaling issues, but it created a deployment nightmare. Here is why I bypassed cloud CI/CD solutions to build a fully on-premise pipeline using Gitea, Jenkins, and Portainer.
