Speed is a feature. Privacy is architecture. Below is everything prospective clients ask before booking an engineering sprint or website build.

CLIENT DECISION MATRIX // HIRING GUIDE

HIRING A DEVELOPER? KEY DUE DILIGENCE

Clear answers to the 7 most critical questions business owners, agencies, and CTOs ask before hiring a web developer.

// 01 · DUE DILIGENCE ★ VERIFIABLE SITES

Look past the portfolio screenshots. Check for real, verifiable projects (live sites you can actually visit), a stack that matches your project (WordPress/WooCommerce vs. custom PHP/Node), and evidence they handle what happens after launch — site speed, SEO, conversion tracking — not just design. A developer who also understands marketing will build something that performs, not just looks good.

// 02 · TEAM STRUCTURE ★ ZERO AGENCY MARKUP

For most small businesses, a skilled full-stack freelancer is the better move: faster communication, no account manager overhead, and you get direct access to the person actually writing your code. Agencies make sense when you need 10+ people on a project simultaneously, but you pay a significant premium for the management layer.

// 03 · ARCHITECTURE ★ 100% CODE OWNERSHIP

Builders trade long-term flexibility for short-term speed. A custom WordPress or PHP build costs more upfront but gives full control over performance, schema markup, and integrations that move rankings and conversions. You also own 100% of your source code and data.

// 04 · PRICING & SCOPE ★ SCOPED MILESTONES

Costs vary by scope, not by a fixed rate card. A simple business site typically runs far less than a custom e-commerce build with integrations. Get a scoped quote based on your actual requirements rather than a generic "starting at" number — anyone quoting before understanding your project is guessing.

// 05 · GLOBAL ADVANTAGE ★ ASYNC EFFICIENCY

You're paying for the same skill set at a significantly lower rate, with the trade-off being time zone overlap rather than technical quality. A good remote developer solves this with clear async communication, documented progress updates, and flexible call scheduling — not by cutting corners on the work.

// 06 · FULL-STACK VALUE ★ CODE + UI DESIGN

A designer focuses on how it looks; a developer builds how it works — the code, hosting, database, and integrations. Most small business sites need both skills, which is why hiring someone who can do full-stack work (design sense plus real engineering) avoids the cost and coordination overhead of managing two separate people.

// 07 · CONTRACT & IP ★ FULL IP HANDOVER

At minimum: scope of work, deliverables, timeline with milestones, payment schedule, who owns the code and content after handover, and what's covered under post-launch support versus what counts as a new request. If a contract is vague on any of these, ask for specifics before signing.

HIRING A DEVELOPER // CLIENT DUE DILIGENCE

Looking for answers on hiring a web developer, freelancer vs agency comparisons, builder tradeoffs, or project pricing?

View Client Hiring Guide Cards

BUILDING AN ONLINE STORE

Conversion comes from fast load times, a frictionless checkout, and accurate conversion tracking. A WooCommerce build with custom schema markup, page caching, and server-side conversion tracking typically outperforms an out-of-the-box store.
It depends on catalog size and custom features, but a well-built WooCommerce store on optimized shared hosting typically runs 1–3 weeks of development. Contact me for a detailed, transparent scoped quote.
A standard WooCommerce build takes 1–3 weeks depending on feature complexity. Adding server-side conversion tracking (CAPI) for Meta, Google, and TikTok is usually a 1–2 day add-on that runs concurrently.

SEO & SITE PERFORMANCE

Real SEO work covers technical audits, on-page optimization with schema markup, and off-page authority building. A 90+ PageSpeed score and clean JSON-LD schema are concrete signs it's done right.
Common causes are bloated themes/plugins, unoptimized images, no caching, and poorly configured shared hosting. Most issues are fixable within 3–5 business days without migrating hosting.
Technical fixes (speed, schema, indexing) can impact rankings within 2–4 weeks. Competitive keyword movements usually take 2–4 months. Any specialist promising page-one rankings in days is using black-hat tactics that risk penalties.
Ask for their own site's search rankings and Core Web Vitals scores — someone who can't rank or speed up their own site can't do it for yours. Be wary of guaranteed "page one in 30 days" promises; legitimate SEO is measurable but gradual, and anyone promising fast top rankings is likely using tactics that risk a Google penalty later.
Technical SEO is the plumbing — site speed, schema markup, mobile usability, crawlability, secure hosting. Content SEO is what you say — keyword-targeted pages, useful answers to real search queries. You need both: great content on a slow, broken site won't rank, and a fast site with no relevant content has nothing to rank for.
Basic on-page SEO (titles, meta descriptions, clear headings, decent content) you can absolutely handle yourself. Technical SEO — schema markup, Core Web Vitals fixes, server-side tracking, structured data — usually needs a developer, since it involves code-level changes most site owners aren't equipped to make safely.
Ask for monthly reporting on specific, checkable metrics: organic traffic in Google Search Console, keyword position changes, PageSpeed scores, and what technical changes were made and why. If someone can't show concrete before/after data, they're not doing measurable work.

AD TRACKING & CONVERSION API

Browser-based tracking (the standard Meta Pixel) loses 20–40% of events to ad blockers, iOS Safari privacy restrictions (ITP), and cookie timeouts. Server-side Conversion API (CAPI) bypasses browser limits and restores accurate reporting.
If you're spending more than $500/month on Meta ads, CAPI is essential. Running Pixel-only means Meta's algorithm is optimizing on incomplete data, driving up your cost-per-acquisition.
Build pages that answer specific, high-intent client questions (like this FAQ), back them with schema markup so search and AI engines cite them, and put a frictionless contact path — WhatsApp, clean form — on every key page.

SAAS & DEVELOPER EVALUATION

Yes. Custom licensing backends handle key generation, domain-locking, activation limits, and webhook-driven revocations without depending on restrictive third-party platforms. See Great 10 in the portfolio.
Evaluate business outcomes, not just visual design: Did they ask about your business goals before talking tech? Does the site load in under 2 seconds? Is tracking set up so you can see ROI? Can they explain what they built without jargon?

WEBSITE BASICS

Start with what the site needs to do — sell products, generate leads, showcase a portfolio — before picking a look. The design should follow the goal, not the other way around. A developer who asks about your business before showing you templates is a good early signal.
Your business name, logo (if you have one), a rough list of pages/sections you need, any existing branding colors or fonts, and — most importantly — clarity on what you want visitors to actually do on the site (buy, call, book, contact). The clearer your brief, the faster and cheaper the build.
A standard business site usually takes 1–2 weeks; an e-commerce store with catalogue, cart, and checkout typically takes 1–3 weeks depending on feature complexity. Timelines stretch mainly when content (copy, images, product data) isn't ready on your end — not from the development itself.
On a custom-built site, you should own 100% of the code, content, and domain — that should be spelled out in your contract. This is different from website builders like Wix, where you're often locked into their platform and can't fully take your site elsewhere.
