Simen Daehlin
I'm a product-driven developer who loves solving complex problems with clean, scalable code. Every bug is a puzzle, every challenge is an opportunity to build something better.
Real Code, Real Impact
These aren't theoretical examples - they're real optimizations and solutions from my actual work. Each one solved a specific business problem with measurable results.
Django Performance Optimization
PythonEnterprise platform optimization - reduced query time by 85%
The Problem
Database queries were taking 2-3 seconds on the user dashboard with 100K+ posts
My Solution
Optimized Django ORM queries with select_related and prefetch_related
Before (Problematic)
def get_user_posts(user_id):
posts = Post.objects.filter(author_id=user_id)
for post in posts:
print(f"Author: {post.author.name}")
print(f"Comments: {post.comments.count()}")
return postsAfter (Optimized)
def get_user_posts(user_id):
return Post.objects.filter(author_id=user_id)\
.select_related('author')\
.prefetch_related('comments')\
.order_by('-created_at')Measured Results
How We Measured
Measured with Django Debug Toolbar and production monitoring
Real-World Context
This optimization was critical for platform stability with 100K+ posts
Proven Track Record
These examples represent real work from my career - not theoretical code samples. Each optimization solved a specific business problem and delivered measurable value to the companies I've worked with.
