Cyril Musila
Full Stack Developer, Web Designer & CEO
Building high-performance websites, web applications, and digital solutions for businesses across Kenya and Africa. 8+ years of turning ideas into powerful digital experiences.
Professional Full Stack Developer in Nairobi, Kenya
I'm Cyril Musila — a passionate Full Stack Developer, Web Designer, and Digital Strategist based in Nairobi, Kenya. Since founding Cyril Creatives Ltd in 2017, I've dedicated my career to helping businesses across Africa establish powerful digital presences that drive real, measurable growth.
With 8+ years of hands-on experience in web development, software engineering, and digital marketing, I've personally led the delivery of 150+ successful projects — from sleek corporate websites and complex e-commerce platforms to full-featured web applications and mobile apps.
My technical expertise spans the entire development stack: from React.js and Next.js on the frontend to Node.js, Python, and Django on the backend, with databases like PostgreSQL, MongoDB, and Firebase. I'm equally comfortable designing pixel-perfect UIs in Figma and architecting scalable cloud infrastructure on AWS and Google Cloud.
Whether you're a startup looking to launch your first website, an established business wanting to optimize your online presence, or an enterprise needing a custom web application — I bring the technical depth, creative vision, and strategic mindset to deliver results that exceed expectations.

The Best Web Developer in Nairobi, Kenya

Every website I build scores 90+ on Google PageSpeed. Speed is a ranking factor, and I ensure your site loads in under 2 seconds — critical for retaining visitors in Africa's growing mobile market.
Built-In SEO from Day One
Unlike many developers who treat SEO as an afterthought, I build SEO into the foundation — semantic HTML, structured data, optimized meta tags, fast loading, and mobile-first design that Google loves.
Enterprise-Grade Security
SSL certificates, secure authentication, encrypted data storage, CSRF protection, and regular security audits. Your website and your users' data are always protected.
Modern Tech Stack
I use cutting-edge technologies like React, Next.js, and TypeScript — the same stack powering Netflix, Airbnb, and Uber. Your website gets the best technology available.
Dedicated, Personal Support
When you work with me, you get direct access to the founder and lead developer — not a junior or middleman. Clear communication, fast turnaround, and accountability.

Payment Integration Developer in Kenya & Africa
I am one of Kenya's most experienced payment integration developers — integrating M-Pesa, Stripe, PayPal, Flutterwave, Pesapal, DPO Group, and virtually any payment gateway into websites, web apps, mobile apps, and scripts — in any programming language or framework.
M-Pesa Integration (Daraja API)
Full M-Pesa STK Push, C2B, B2C, B2B, Reversal, Account Balance, and Transaction Status APIs. I integrate Safaricom Daraja API into any platform — PHP, Node.js, Python, Laravel, Django, WordPress, WooCommerce, or custom apps.
Stripe Payment Integration
Stripe Checkout, Payment Intents, Subscriptions, Connect (marketplace payments), Webhooks, 3D Secure, and multi-currency billing. Integrated into React, Next.js, Node.js, Python, Laravel, and mobile apps.
PayPal Integration
PayPal REST API, Smart Payment Buttons, Subscriptions Plans, PayPal Commerce Platform, IPN webhooks, and PayPal Payout for mass payments — embedded in any website, mobile app, or backend script.
Flutterwave Integration
Flutterwave Rave and v3 APIs for card payments, mobile money (M-Pesa, Airtel Money, MTN MoMo), bank transfers, USSD, QR codes, and virtual accounts across 30+ African countries.
Pesapal Integration
Pesapal IPN (Instant Payment Notification), payment iframe embedding, order tracking, refunds and reversals — widely used for Kenyan e-commerce, schools, utilities, and event ticketing platforms.
DPO Group & Other Gateways
DPO Group (DirectPay Online), Paystack, Cellulant, IntaSend, JumiaPay, Binance Pay, crypto payments (USDT/BTC via CoinGate/Coinbase Commerce), and any custom payment provider via REST API or SDK.
Any Language. Any Platform. Any Payment.
Whether your stack is PHP, Python, Node.js, Ruby, Java, .NET, Go — or your platform is WordPress, Shopify, Magento, custom React/Next.js, or a native mobile app — I can build a secure, reliable payment integration that works.
How I Build Secure Payment Systems
My payment integration process is thorough, security-first, and tested end-to-end — from sandbox testing through to live transactions — so your customers always have a seamless checkout experience.
Payment Architecture & Gateway Selection
I analyse your business model, target markets, currencies, and transaction volumes to recommend the optimal payment stack — whether that's a single gateway like M-Pesa or a multi-gateway setup supporting cards, mobile money, and crypto simultaneously.
API Integration & Custom Development
I handle the full SDK/API integration in your codebase — authentication, request signing, payload handling, idempotency keys, and all edge cases. Whether it's Daraja's OAuth tokens or Stripe's webhook signatures, every detail is handled correctly.
Security, Compliance & Encryption
Payments require watertight security. I implement PCI-DSS-aligned practices: HTTPS enforcement, tokenisation, encrypted credential storage, CSRF protection, IP whitelisting for webhooks, and secure server-side validation — never trusting client-side data.
Webhooks, IPN & Real-Time Callbacks
I build reliable webhook and IPN (Instant Payment Notification) handlers that update your database, trigger order fulfilment, and send customer confirmations in real time — even handling duplicate events and network retries gracefully.
Sandbox Testing & End-to-End QA
Every integration is fully tested in the payment provider's sandbox environment — simulating successful payments, failures, cancellations, refunds, and edge cases — before going anywhere near live customer transactions.
Go-Live, Monitoring & Ongoing Support
After a controlled live launch, I set up payment monitoring, error alerting, and reconciliation logging so you always know what's happening with your money. I remain available for support, currency additions, or gateway upgrades as your business grows.
