What We Do

Three things.
Done right.

awaisyasin.co focuses on a tight set of disciplines where depth beats breadth — backend API engineering, cloud infrastructure, and async systems architecture.

No agency padding. No handoffs. You work directly with the engineer shipping the code.

⚡

API & Backend Engineering

Production-grade REST and GraphQL APIs with Django or FastAPI. Designed for performance from day one — proper serialisation, DB query budgets, caching layers, and auth systems that don't leak.

☁️

AWS Cloud Architecture

Right-sized, cost-aware AWS infrastructure that scales on demand and costs sensibly when it doesn't. ECS deployments, RDS tuning, serverless pipelines — or a full Terraform-based setup from scratch.

ECS / EKS RDS / Aurora Lambda Terraform CloudFormation

🔄

Async Systems & DevOps

Task queues, event-driven pipelines, background workers, and CI/CD that deploys without drama. Built with Celery, SQS, or custom patterns — so your web process stays fast and your queue handles the weight.

How We Work

Straightforward.
No surprises.

Discovery Call

30-min session to understand your architecture, constraints, and goals. No sales pitch — just technical questions.

Scoping & Proposal

A clear technical spec, timeline, and fixed or milestone-based pricing. You know exactly what you're getting.

Build & Iterate

Weekly async updates, PR reviews open to your team, and Slack access throughout. You're never left guessing.

Ship & Handoff

Production deployment, docs, runbooks, and a 30-day support window. Your team can own it from day one.

Selected Work

Real problems.
Real results.

★ Featured Case Study

Multi-Tenant SaaS Platform
— 200k Users, 65% Faster APIs

Led backend architecture for a B2B SaaS serving 200k+ users across 800+ tenant organisations. Identified N+1 queries and missing DB indexes that were silently degrading API response times. Introduced a Redis cache-aside layer, rewrote critical ORM queries using select_related and bulk_create, and migrated background jobs to an async Celery + SQS pipeline. Deployed on AWS ECS with blue/green deploys — 18 months running at 99.98% uptime.

Serverless AI Content Pipeline

AWS Lambda + SQS pipeline running OpenAI processing at scale. DynamoDB indexing, S3 storage, auto-scaling — replaced a $3.2k/month managed platform at 1/8th the cost.

The Engineer

Hi, I'm Awais Yasin.

I started awaisyasin.co after 5 years of building backend systems across fintech, SaaS, and e-commerce — enough time to learn what actually breaks in production and how to build things that don't.

The studio is intentionally small. I work with a tight roster of clients at a time, which means you get direct access to the engineer building your system — no account managers, no juniors doing the work after the pitch.

🔬

Performance-obsessed

Every project starts with profiling. Measurable improvements, not guesses.

📖

Documentation-first

Your team inherits clean code, runbooks, and architecture diagrams — not a mystery box.

🤝

Async-friendly

Remote-first, timezone-flexible, and built for distributed teams with clear written communication.

Client Words

What clients
actually say.

★★★★★

"Awais rewrote our Django ORM layer and cut query count from 400 to 12 on our main dashboard. The kind of backend engineer who actually reads your code before touching it."

James Keller

CTO · Datastride Inc.

★★★★★

"We hired awaisyasin.co to move our monolith to ECS. Came in, assessed, proposed a plan, and executed it clean — zero downtime migration, on schedule. Will engage again."

Sara Aldrich

VP Engineering · BuildFast

★★★★★

"Our Celery pipeline was a mess of retries and timeouts. Awais diagnosed and rebuilt it in 3 weeks — now it processes 2M jobs a day without a single alert. Exceptional."
