Database Query Timeout - Complex Queries Too Slow
Database queries timeout or take too long (>5 seconds). Complex queries with joins or aggregations are slow.
API endpoints that query database time out or users see loading spinners for too long.
Error Messages You Might See
Query execution timeout after 30 seconds
Database connection timeout
Slow query warning: exceeded 1 second
Database lock timeout
Common Causes
- Missing database indexes on frequently queried columns
- N+1 queries - fetching parent then all children separately
- Fetching more data than needed (select * instead of specific columns)
- Complex joins without proper indexes
- Large result sets without pagination
How to Fix It
Add indexes: CREATE INDEX idx_user_email ON users(email)
Use eager loading: Prisma.findUnique({ include: { posts: true } }) instead of separate queries
Select specific fields: select { id: true, email: true } instead of full objects
Paginate large results: limit 100, offset (page-1)*100
Profile queries: explain analyze SELECT... in database
Cache frequently accessed data: use Redis for hot data

Solo dev shipping production apps with AI-assisted development. I specialize in rescuing broken Lovable/Bolt/Cursor builds and taking them to production. 10+ apps shipped including SaaS CRMs, gaming platforms, real estate tools, and Discord bots. Stack: Next.js 16, TypeScript, Tailwind CSS, FastAPI, PostgreSQL, Prisma. I use Claude Code with 50+ custom skills for rapid delivery. Average turnaround: 2-4 weeks from broken prototype to production.
Basel Issmail
’m a Senior Full-Stack Developer and Tech Lead with experience designing and building scalable web platforms. I work across the full development lifecycle, from translating business requirements into technical architecture to delivering reliable production systems.
My work focuses on modern web technologies, including TypeScript, Angular, Node.js, and cloud-based architectures. I enjoy solving complex technical problems and helping teams turn product ideas and prototypes into working platforms that can grow and scale.
In addition to development, I often collaborate closely with product managers, business analysts, designers, and QA teams to ensure that solutions align with both technical and business goals.
I enjoy working with startups and product teams where I can contribute both as a hands-on engineer and as a technical partner in designing and delivering impactful software.

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.
Rudra Bhikadiya
I build and fix web apps across Next.js, Node.js, and DBs.
Comfortable jumping into messy code, broken APIs, and mysterious bugs.
If your project works in theory but not in reality, I help close that gap.
You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
How do I know if a query is slow?
Run EXPLAIN ANALYZE in database. Look for sequential scans (bad) vs index scans (good)
What's N+1 query problem?
Fetch 1 user (1 query), then fetch posts for each user (N queries). Use eager loading to do 2 queries total
Should I cache everything?
No, cache hot data. Use Redis for frequently accessed, slow-to-compute results. Set reasonable TTL
