Live Cohort · 8 Weeks · First Batch: July/August 2026

Stop Building Like a Developer.
Start Thinking Like an Architect.

A Hindi/Hinglish cohort where experienced backend developers learn how architects actually think. Not another high-level whiteboard tour of 28 systems.

We take ONE real production system, build it deep, deploy it, scale it, test its failure modes, and document every single decision.

You walk out able to defend any system design, in a design review or a 45-minute interview.

The Shift

Developer Approach vs Architect Approach

Most engineers keep optimizing code. Architects optimize systems, trade-offs, and decisions.

Developer Approach

Picks the tech stack on Day 1 based on hype
Builds features first, writes docs never
One database for everything, figures it out later
Deploys on Friday evening and prays over the weekend
Adds monitoring after the first production outage
"It works on my machine" is the final test

Architect Approach

Defines Non-Functional Requirements, then picks tech deliberately
Writes Architecture Decision Records (ADRs) before writing code
Asks what consistency and access pattern each operation needs, then chooses storage deliberately — one Postgres until the data shape demands more
Knows when blue-green or canary is worth the cost — and when it is theatre at your scale
SLO dashboards, distributed tracing, and alerts configured before launch
Load tests to 1 lakh orders/day, chaos testing, and FinOps cost modeling

Skills & copilot-instructions.md

Project-level architectural context so every suggestion aligns with your NFRs, ADRs, and system constraints. Not random code from the internet.

Prefer the terminal? In Week 1, we'll also cover Claude Code as an alternative for developers who think faster in the command line. You pick your weapon. The architectural thinking stays the same.

Week by Week

8-Week Curriculum

Every week builds on the last. Every topic earns its place. No random topics thrown together because they look good in a syllabus. And every week ends with a 15-minute interview transfer drill, the same framework you use in a 45-minute system-design interview.

Week 1 Architect the Monolith

Foundation & Domain Modeling

  • · Developer → Architect: what changes, and why the thinking transfers across .NET, Java, Go, or Node — the patterns are the product, not the language
  • · Requirements engineering: Functional vs Non-Functional Requirements, plus back-of-envelope estimation (traffic, storage, bandwidth) for Tadka
  • · ADRs + the 4-step system-design framework: the same structure you use to defend a design in a 45-minute interview
  • · Domain-Driven Design essentials (Bounded Contexts, Aggregates) and schema-per-domain — code boundaries now, service boundaries later
  • · Architecture diagrams that communicate clearly; AI as an optional thinking aid, never a replacement for judgment
🎯Interview layer: Instructor solves a Notification System live — you watch the six-move framework (which is the ADR) flow end to end.
Can justify why Tadka starts as a monolith (trade-offs + revisit triggers documented), with a clean domain model and schema-per-domain. Estimation done, Tadka running locally.
Week 2 Architect the Monolith

Monolith API, State Machine & Hardening

  • · API-first contract design: RESTful patterns, versioning trade-offs, RFC 7807 error contracts
  • · The order state machine: legal transitions enforced in the domain, illegal ones rejected (422)
  • · Tadka monolith: full order lifecycle in a single app, single database, single transaction
  • · Hardening the flow, failure-first: idempotency (safe retries), optimistic concurrency (lost-update races), in-process domain events
  • · Hands-on: schema/API-versioning workshop and state-machine exercises
🎯Interview layer: Instructor solves Booking / flash-sale (BookMyShow, IRCTC Tatkal) — seat locking, fairness, oversell; transfers this week's state machine + concurrency.
Can build a monolith with boundaries clean enough to extract later. The order-to-delivery flow survives retries and concurrent writes.
Week 3 Architect for Scale

Scaling the Monolith

  • · PostgreSQL deep dive: indexing, EXPLAIN ANALYZE, query plans, read replicas, connection pooling
  • · Table partitioning vs sharding: consistent hashing, and what 1 lakh vs 1 crore daily orders demands
  • · Redis deep dive: Cache-Aside pattern, cache stampede prevention, distributed locks, TTL strategy
  • · CAP theorem in practice: classify Tadka features by their real consistency needs
  • · Decision exercises: pick the right cache invalidation strategy from 4 real options
  • · Realtime order tracking: Server-Sent Events (SSE) over a Redis pub/sub backplane — push, not poll, and correct across multiple instances
🎯Interview layer: Paired drill: URL Shortener or Rate Limiter — cache-as-the-product, shared Redis state, token bucket, consistent hashing.
Can explain what breaks at 1 lakh orders/day, why Redis comes before service extraction, when caching stops being enough, and how to push realtime updates (SSE + Redis backplane) instead of polling.
Week 4 Architect for Scale

Modular Monolith & First Service Extraction

  • · Modular monolith refactor: domain events with MediatR, module boundaries, vertical slices
  • · When to extract a service: the decision framework (scaling, team ownership, deployment cadence, compliance)
  • · First extraction: Payment Service with HTTP bridge (Kafka motivation introduced)
  • · Architecture Review: spot the flaws in a deliberately broken system diagram
  • · Event-driven architecture: why we need it now, and why we did not need it before
🎯Interview layer: Paired drill: Design a Payment System — idempotency, ledger, saga, reconciliation.
Can explain why Payment was the right first extraction — fault and PCI isolation, not latency (latency was fixed in-process first) — and why HTTP came before Kafka.
Week 5 Architect the Distributed System

Distributed Backbone & Security

  • · Saga pattern for distributed transactions: why a simple DB transaction no longer works
  • · Idempotency, deduplication, and why exactly-once is rarely as simple as it sounds
  • · Transactional Outbox + Inbox, event schema versioning: the patterns that make distributed systems survivable
  • · Authentication (JWT) and Authorization (RBAC + resource-ownership), validated per-service — defense in depth
  • · PII, GDPR right-to-be-forgotten, and PCI scope: data classification as a security concern
🎯Interview layer: Paired drill: Chat System (WhatsApp) — fan-out, ordering, delivery receipts, dedup.
Can design distributed workflows with Kafka, Saga, Outbox, and idempotency, and secure them per-service. 2 services (monolith + Payment) with real failure-mode thinking; Delivery + gateway land Week 6.
Week 6 Architect the Distributed System

Completing the Service Split & Cloud Deployment

  • · Extract the remaining services: earning the last service boundaries (4 services + gateway)
  • · Zero-downtime migrations: the expand-and-contract pattern, plus the hard part nobody teaches — backfilling millions of rows under live traffic without locking the table or saturating replication
  • · Deploy day, black-box: get all 4 services + gateway live on managed cloud with pre-built infrastructure — results, not HCL syntax
  • · The decisions that matter: ALB/target-group routing, container orchestration choices (ECS vs Lambda vs Kubernetes), network hops, and the shape of the monthly bill
  • · Reading the cloud cost model: what each architectural choice does to the AWS invoice (we model it; you do not pay for a week of infra iteration)
🎯Interview layer: First full 60-minute mock: Design Uber / Swiggy dispatch — geospatial index, nearest-N riders, live location, surge.
Can explain how deployment shape changes blast radius, release cadence, and cost — and see all 4 services + gateway running on managed cloud.
Week 7 Architect for Production

Observability, Reliability & Failure Thinking

  • · Structured logging, metrics collection, distributed tracing across all services
  • · Vendor evaluation: pick your observability stack with real pricing constraints
  • · Set your own SLOs before seeing ours. Most students aim too high.
  • · Circuit breakers, retries with backoff, timeouts, bulkhead pattern
  • · Chaos engineering, live: kill a dependency (Redis, the payment service), watch the system degrade gracefully and recover, not cascade
  • · Backpressure and load shedding: what to protect when your system is overwhelmed
  • · Failure Mode Analysis: for every arrow in the architecture, what breaks and what is the blast radius?
🎯Interview layer: Mock: Hotstar live (thundering herd) or Instagram Feed, plus the interview-communication session — driving the room, raising trade-offs unprompted (the L5→L6 signal).
Can reason about SLOs, failure blast radius, and load shedding strategy, not just configure dashboards and retries.
Week 8 Architect for Production

System Design Case Studies, Load Testing & Portfolio

  • · System design teardowns: Swiggy (delivery optimization), Zomato (search at scale), Razorpay (payment reliability)
  • · Pattern transfer drills: apply Tadka patterns to unfamiliar problems the same way you would in an interview
  • · Load testing with k6 + AWS cost modeling: breaking your system and knowing what it costs
  • · Final reflection: your first 3 architectural decisions if you started a new startup tomorrow
  • · Final architecture document and interview pack: the portfolio artifacts that demonstrate judgment
🎯Interview layer: Design-Swiggy masterclass + final instructor mocks (rubric-scored, recorded) — the whole system in one 45-minute answer.
Can apply Tadka patterns to unfamiliar system design problems. Portfolio shows architectural judgment, not just code.

What This Cohort Is NOT

Honest expectations before you commit your time and money.

Not a line by line syntax tutorial. You should already know how to code. We do build real code live (Copilot and Claude Code help), but the focus is the decisions behind it, not the syntax.

Not a passive video series. You will build, deploy, and write ADRs.

Not a certification prep course. We focus on real-world engineering, not exam memorization.

Not a high-level summary of 28 random systems. We go deep into ONE production architecture.

Not a tool checklist. MongoDB, Elasticsearch, Event Sourcing, and blue-green deployment are discussed as trade-offs, not forced into the build.

Not for freshers. You need to have shipped something to production and felt the cost of a decision made without enough thinking, whether that was 4 years in or 18.

Not a course where you configure Kafka without understanding when not to use it. Every tool is introduced only when the architecture earns it.

What People Are Saying

Real feedback from mentees and the YouTube community.

"One of the most valuable career conversations I've had. He didn't give me a generic roadmap. He listened, understood my exact situation, and gave me a clear, practical direction I could act on immediately. The focus on fundamentals first, and knowing WHEN to use something rather than just HOW, completely shifted my thinking."
