SaaS platform to chat with any PDF — end-to-end RAG pipeline built from scratch.

SaaS platform to chat with any PDF — full RAG pipeline engineered from scratch without black-box libraries. 384-dim embeddings in pgvector (cosine + IVFFlat), hybrid search (dense vector + BM25) with RRF fusion, end-to-end LLM streaming (ndjson) from FastAPI → NestJS → Next.js with page-level citations. Zero-cost local embeddings via sentence-transformers; production async Python with SQLAlchemy async sessions.

Real-time job-processing system — a DevOps showcase with Kubernetes auto-scaling and GitOps CI/CD.

Real-time distributed job-processing system — a DevOps showcase deployed on Kubernetes with GitOps CI/CD. Redis + BullMQ async job queue with live Socket.IO status updates; K8s HPA auto-scaling workers from 2 to 10 replicas at 50 concurrent jobs. GitOps pipeline with Argo CD and GitHub Actions (lint → build → push → infra update); Redis AOF persistence so jobs survive pod restarts.

Configurable white-label storefront for multiple clients — multi-tenancy and micro-frontend architecture.

6-service Dockerized monorepo (Next.js 15 + Express + PostgreSQL + Redis + BullMQ) built with Clean Architecture across 11 modules and 15 database models. Stripe webhook-driven payments, runtime theme engine (DB → CSS custom properties enabling hot-swap templates without redeployment), RTK Query admin panel with shadcn/ui, Redis caching for product and theme read paths, and Next.js 15 ISR with dynamic sitemap.

Backend-only social platform — microservices, API gateway, and inter-service messaging.

Backend-only social platform built as a microservices architecture showcase. 5 independently deployable services behind an API Gateway with JWT auth, Redis caching for hot read paths, and RabbitMQ for async inter-service messaging. Structured logging via Winston across all services.
