| 🏗️ Project | 💡 What makes it special | 🛠️ Stack |
|---|---|---|
| Schematix — Distributed Schema Orchestration Platform 🆕 | Intelligently infers schema structure from multi-source data (S3, Azure Blob, GCS, APIs), applies async processing with pluggable ingestion strategies and extensible format resolvers to auto-generate optimized DB schemas across cloud environments | Java · Spring Boot · S3 · Azure Blob · GCS · Async · Multi-Cloud |
| RunetSu — Sandboxed Code Execution Platform | Built a custom AST-based static analysis engine from scratch — no third-party parser. Secure, sandboxed execution of untrusted code at scale | Java · AST · Spring Boot · Docker |
| GraphNova — Distributed Graph Database | Horizontally scalable distributed graph DB with custom partitioning and replication strategies | Java · Distributed Systems · Custom Consensus |
| dash-stream — Video Streaming Platform | YouTube/Netflix-style streaming with FFmpeg transcoding, HLS/DASH adaptive bitrate, WebSocket upload progress, and plugin-based multi-cloud storage (S3 · Azure · GCP) | Java · FFmpeg · HLS · Spring Boot · S3 |
| Multi-Cloud-Infrastructure | Terraform configs for provisioning across AWS + Azure + GCP simultaneously | Terraform · HCL · Multi-Cloud |
| OpenTicket | Production-grade microservice ticket system with Kubernetes orchestration | Node.js · TypeScript · Docker · K8s · Skaffold |
| 2FA-Exchange | Secure contact management API with full 2FA implementation | NestJS · TypeORM · Docker · Security |
