Backend engineering for products that can't afford unreliable infrastructure
Payments. APIs. Integrations. Infrastructure. We help growing companies solve the backend problems that become expensive as products scale.
Before Chelon Labs, our founder built fintech infrastructure at scale
Need someone to solve a backend or integration problem like this?
Talk to an engineer →Your product is growing. Your backend is showing it.
These are the problems that start appearing when products move from early traction to real scale. If any of these sound familiar, we can help.
Slow APIs
Response times creeping up as traffic grows. Database queries that used to be fast are now bottlenecks.
Payment failures
Transactions dropping, provider outages causing revenue loss, no fallback when things go wrong.
Fragile integrations
Third-party APIs breaking unexpectedly. Webhook handlers that miss events. No retry logic.
Technical debt
Code that's hard to change. Features that take weeks instead of days. Engineers afraid to touch certain parts.
Growing cloud costs
Infrastructure bills climbing faster than revenue. Resources running inefficiently. No visibility into what's costing what.
Scaling anxiety
Not sure if the system will handle the next traffic spike. No load testing. Hoping nothing breaks.
Dealing with one of these? Let's figure out what's actually causing it.
Talk to an engineer →Build · Integrate · Fix · Scale
Four ways we solve backend problems for growing companies. Each engagement starts with understanding what's actually slowing your product down.
Build
New backend systemsAPIs, transaction systems, databases, authentication, background processing. We build the backend infrastructure that powers your product.
- REST & gRPC APIs
- Transaction Processing
- Database Design
- Authentication & Authorization
- Queue Systems & Caching
- Microservices Architecture
Integrate
Connect your systemsPayments, banking, KYC, identity, third-party APIs, webhooks. We connect your product to the external services it needs to work.
- Payment Gateway Integration
- Banking & Financial APIs
- Identity Verification (KYC)
- Webhook Infrastructure
- Provider Abstraction Layers
- Multi-Provider Routing
Fix
Repair and modernizePerformance problems, technical debt, architecture issues, migrations. We fix existing systems without breaking what works.
- Performance Tuning
- Technical Debt Reduction
- Legacy System Migration
- Database Migration
- API Modernization
- Architecture Refactoring
Scale
Make infrastructure reliableCloud deployment, CI/CD, observability, performance and cost optimization. We make your production infrastructure predictable.
- Docker & Kubernetes
- CI/CD Pipelines
- Cloud Deployment (AWS, GCP)
- Monitoring & Observability
- Performance Optimization
- Cost Management
When your product outgrows its backend, call Chelon Labs.
We're not a general agency that happens to do backend work. We're backend engineers who solve the specific problems that appear when products start scaling.
The engineering team you bring in when the backend becomes complicated
Production Experience, Not Theory
Systems processing ₦106M+ monthly. 6 payment providers integrated. 40% faster response times. These aren't projections — they're results from real fintech infrastructure.
Integration Expertise
Payments, banking APIs, identity verification, webhooks. We know where the edge cases live and how providers actually behave under load.
Senior Engineering, Direct Access
No layers of account managers. No handoffs to junior developers. You work directly with the engineer building your system.
We typically help when...
- Your backend is becoming a bottleneck as traffic grows
- You need multiple payment providers integrated reliably
- Technical debt is slowing down your engineering team
- You're launching a transaction-heavy product
- Your team needs senior backend capacity without a full hire
- Cloud costs are growing faster than your revenue
Built on Production Fintech Experience
I founded Chelon Labs to help growing technology companies solve the backend, integration, and infrastructure problems that become expensive as products scale.
Before starting this studio, I spent years building backend infrastructure for a Nigerian fintech company processing ₦106M+ in monthly transactions. I've integrated 6 different payment providers, built transaction systems handling thousands of daily payments, and optimized cloud infrastructure to cut costs by 25% while improving response times by 40%.
I've built the systems that most agencies only diagram — payment gateways, multi-provider transaction routing, settlement workflows, and the cloud infrastructure that keeps them running at scale.
When you work with Chelon Labs, you get direct access to senior engineering expertise focused entirely on your backend and infrastructure challenges. No layers of account managers. No handoffs to junior developers.
