Performance
Brittle, undocumented APIs
APIs built without proper versioning, documentation, and error handling become technical debt that slows every future feature — and breaks clients silently.

Architecture
Disconnected business systems
CRM, ERP, payment, KYC, and core banking tools that do not talk to each other create data silos, manual reconciliation, and missed compliance checks.

Scaling limits on monolithic apps
Monolithic architectures that cannot be broken into services become bottlenecks. The wrong refactoring approach can make things worse, not better.

WHY CODEFLAMME
Not Another Offshore Vendor
We know the hesitation. Here's exactly how we're different.
You Talk to the People Building It
No account managers relaying messages. You're in direct contact with the founder and senior engineers on your project — every sprint, every decision.
No Bench Rotation
The team that scopes your project is the team that ships it. We don't swap engineers mid-project to free them up for someone else.
NDA Before We Talk Details
Your idea and IP are protected from the first real conversation — not after contracts are signed.
Full IP, Zero Strings
Every line of code, every design file, transfers to you on delivery. No licensing, no retained rights, no surprises.
Our Approach
How We Build APIs That Your Team and Clients Will Love
We design API contracts before writing a single line of implementation code. Every API is designed around its consumers — what data they need, in what format, at what speed. We write comprehensive OpenAPI / Swagger documentation, implement proper versioning from v1 day one, and build rate limiting and authentication as standard features — not afterthoughts.
For fintech platforms, contracts also encode money and identity realities: idempotent payment and ledger writes, clear PCI vs non-PCI service boundaries, KYC/AML webhook handling with retry and evidence retention, and open-banking style consent scopes so third-party account data never becomes a free-for-all dump into your core. Payment and identity events are modelled as durable workflows — not fire-and-forget HTTP calls — so ops and compliance can replay, reconcile, and prove what happened.
- API contracts designed before any implementation code
- OpenAPI docs, versioning, and rate limiting from v1
- Built around what consumers need — data, format, speed
- Fintech builds: PCI scope boundaries, idempotent money movement, audit trails

Capabilities
What We Deliver
REST, GraphQL, and integration rails — including PCI-scoped payments, KYC/AML, open banking, and ledger sync for fintech platforms.
- 01
REST API Design & Development
Resource-oriented REST APIs following OpenAPI specification with versioning, authentication, rate limiting, and full Swagger documentation.
- 02
GraphQL API Development
Schema-first GraphQL APIs with query depth limiting, persisted queries, and DataLoader for efficient database access patterns.
- 03
Payment & Processor Integrations
PCI-scoped payment APIs beyond a basic Stripe checkout — card processors, payouts, refunds, disputes, webhooks, and vaulted tokens with clear CDE boundaries so raw card data stays out of your application tier.
- 04
KYC / AML Integration Patterns
Identity and screening providers wired for onboarding: document + biometric checks, watchlist screening, ongoing monitoring webhooks, case statuses, and evidence trails your compliance team can audit.
- 05
Open Banking APIs
Account aggregation and payment-initiation style integrations with consent, token refresh, and scoped data sync — resilient when providers rate-limit, rotate schemas, or revoke connections mid-session.
- 06
Ledger & Transaction Sync
Double-entry friendly ledger APIs and reconciliation jobs that keep balances, pending states, and external processor events aligned — with idempotency keys, outbox patterns, and replay-safe consumers.
- 07
Third-Party Integrations
HubSpot, Salesforce, Slack, Twilio, SendGrid, and the rest of your product stack — same contract-first approach as payments and KYC rails.
- 08
Microservices Architecture
Breaking monolithic applications into independently deployable services with proper service boundaries, message queues, and API gateways.
- 09
Webhook Systems
Reliable webhook delivery infrastructure with retry logic, signature verification, event logs, and delivery dashboards — including payment and KYC provider callbacks.
- 10
Real-Time APIs
WebSocket and Server-Sent Event implementations for real-time features — live dashboards, notifications, chat, and collaborative tools.
- 11
API Gateway & Middleware
Kong, AWS API Gateway, or custom middleware for authentication, rate limiting, logging, and routing across multiple services.
- 12
API Migration & Versioning
Migrating legacy SOAP or undocumented APIs to modern REST/GraphQL while maintaining backward compatibility for existing clients.
