Can I complete this while working full-time? Absolutely! Our courses are designed for working professionals. Track 2 takes 12 weeks at 15-20 hours/week (weekends). Track 3 takes 22 weeks. You can study evenings and weekends while continuing your current job. #### Do all tracks include the 3 BankForge projects? YES! Even Track 1 (₹20K) includes all 3 BankForge projects as instructor demonstrations: BankForge Core (~100 files), BankForge-DBA-Operations, and BankForge-AI. These are worth ₹15-20K alone and included in every track! #### I have 5 years of PostgreSQL experience. Which track? **Track 2** (Senior DBAs, 5-9 years). You'll build SampleBank hands-on, deploy to AWS, set up production monitoring, and master cloud operations. Perfect for moving from mid-level to senior/lead roles. #### What's the difference between Track 1 and Track 2? **Track 1:** You STUDY 4 production projects (ProductionDB + 3 BankForge) as reference code. No building. **Track 2:** Everything in Track 1 PLUS you BUILD SampleBank yourself, deploy to AWS, set up monitoring, CI/CD, security. Hands-on experience with portfolio project! #### Why does Track 1 NOT include HA troubleshooting if it includes HA configuration? Track 1 teaches you how to SET UP HA (Patroni, replication). Track 2 & 3 teach you how to TROUBLESHOOT when HA fails at 2 AM. Troubleshooting requires hands-on incident simulation which Track 1 doesn't include. #### I'm an Oracle DBA for 6 years. Which track should I take? **Track 2** (Senior DBAs). All tracks include ora2pg (Oracle → PostgreSQL migration), but Track 2 gives you hands-on cloud deployment and modern DBA workflows. Perfect for Oracle → PostgreSQL transitions. #### Is Track 3 worth ₹20K more than Track 2? For working professionals earning ₹35-50 LPA: YES! Track 3 includes advanced mastery (automation, K8s, 100K TPS, system design, career coaching). The salary jump from Senior (₹40L) to Staff (₹55-60L) is ₹15-20L/year. ₹55K investment pays for itself in 1-2 months of extra salary. #### What's the difference between DBA and DBRE? **DBA:** Operates databases, handles backups, monitors performance, responds to incidents. **DBRE:** Owns database platforms, builds automation, designs for scale, prevents incidents, leads teams. Track 3 trains you for DBRE/Staff Engineer roles. #### Do you offer payment plans or EMI? Yes! Track 1: 2 installments (₹10K x 2) | Track 2: 3 installments (₹12K x 3) | Track 3: 4 installments (₹14K x 4). Contact us for EMI details. #### Is there a money-back guarantee?
