// PRODUCTION DISCIPLINE

The 4-Stage Engineering Lifecycle

How we take complex business requirements from napkin concept to bulletproof live deployment.

STAGE 01 · WEEK 1

Architecture Discovery

Schema Modeling & Architecture Blueprint

We define data models, relational foreign keys, Daraja M-Pesa payment flows, user permission trees, and edge CDN cache policies before writing a single line of production code.

STAGE 02 · WEEKS 2–3

Frontend & APIs

Sub-Second Frontend & API Compilation

Building accessible, conversion-engineered components using Next.js 14 and Vanilla CSS tokens with continuous live staging previews and end-to-end type validation.

STAGE 03 · WEEK 4

Stress Testing

Payment Webhook Verification & Stress Testing

Simulating network latency drops, Daraja STK timeout retries, double-click transaction prevention, and cross-browser stress testing across mobile devices and low-bandwidth networks.

STAGE 04 · LAUNCH & SCALE

SLA Monitoring

Edge CDN Deployment & Continuous SLA Monitoring

Zero-downtime production deployment to global edge nodes with automated daily offsite database backups, SSL enforcement, and 24/7 server health telemetry.

// FREQUENTLY ASKED QUESTIONS

Common Questions & Answers

Clear answers about pricing, delivery timelines, M-Pesa integrations, and code ownership.

Project costs depend entirely on architecture, integrations, and feature complexity. Typical corporate websites start from KES 35,000 – 75,000, custom e-commerce platforms with automated Daraja M-Pesa STK integration range from KES 65,000 – 150,000, and complex custom SaaS web applications / multi-branch portals are scoped from KES 150,000+. All projects receive a detailed fixed milestone quote with zero hidden fees.

A standard high-performance business website is typically delivered within 1 to 2 weeks. E-commerce platforms with payment gateway testing take approximately 2 to 3 weeks, while complex full-stack web applications take 4 to 8 weeks depending on scope. Staging links are provided within days so you see real-time progress.

Yes, Safaricom Daraja 2.0 FinTech integration is one of my deepest core specializations. I implement Lipa na M-Pesa Online (STK Push), C2B Paybill/Buy Goods IPN validation, automated B2C payouts, and idempotent Redis queue workers that guarantee zero dropped payment callbacks and instant ledger reconciliation.

Absolutely. I perform comprehensive performance audits, eliminating heavy visual page builders, optimizing slow database queries, minifying assets, and setting up edge caching with Cloudflare to bring your Google PageSpeed score to 95+ and load times under 1 second.

Yes, 100%. Upon final project milestone settlement, you receive complete ownership of all Git source repositories, database schemas, graphics, and server credentials. You are never locked into proprietary subscriptions or agency retainers.

Yes! All builds include 30 days of complimentary post-launch support and bug fixes. After launch, you can choose flexible monthly maintenance plans covering automated offsite backups, security patching, API monitoring, and ongoing feature updates.
