Engineering Deep Dive

A system-design walkthrough for tech talks and internal reviews. Architecture diagrams on the left, tradeoffs on the right, code where it counts.

Best for

Conference talks, internal architecture reviews, and onboarding sessions where the audience is technical and wants the real details, not a marketing version.

Slide preview

Slide 1 - title

Engineering Deep Dive

System name
Your name, team

Slide 2 - content

The problem we were solving

Workload shape
Constraints: latency, throughput, cost
What we ruled out

Slide 3 - split

Architecture at a glance

Request path
Storage layer
Async path

Slide 4 - content

The hot path

Step 1 - ingress
Step 2 - validation
Step 3 - write
Step 4 - fanout

Slide 5 - split

The storage decision

Option A - Postgres
Option B - Dynamo
Why we picked B

Slide 6 - code

The query that matters

SELECT id, payload FROM events
WHERE user_id = $1 AND ts > now() - interval '1 hour'
ORDER BY ts DESC LIMIT 100;

Slide 7 - content

Tradeoffs we accepted

Eventual consistency on the read replica
Higher write amplification
Simpler ops

Slide 8 - content

What we would do differently

Ship the read replica earlier
Instrument from day one
Do not hand-roll the queue
