Stop paying the freelancer lottery
and the bloated agency tax.
When your site crashes, checkouts fail, or your backlog stalls, you don't need a 3-week sales cycle or an amateur patching symptoms. You need a 20-year senior engineer who fixes the root cause immediately.
The Flaky Freelancer
- Ghosts mid-sprint: Juggling 8 clients, vanishes when critical bugs emerge or updates crash your store.
- Patches symptoms with plugin bloat: Installs 10 extra plugins instead of diagnosing the root cause, wrecking your site speed.
- Runaway hourly invoices: Incentivized to work slowly and bill extra hours; the final invoice is always an expensive shock.
The Bloated Agency
- The bait-and-switch: Senior partners pitch your business; your actual codebase is handed off to junior developers or offshore contractors.
- $5,000–$15,000/mo minimums: Heavy retainers with aggressive change-order fees for every minor adjustment.
- Endless meeting fatigue: 5 hours of discovery calls, status check-ins, and slide decks while your 2-hour fix sits untouched for 3 weeks.
The Full-Time Senior Hire
- Months to hire: 2–3 months of recruiter fees, technical interviews, and notice periods.
- Massive overhead: $150,000+/year ($12,000+/mo) before taxes, healthcare, equipment, and equity.
- Downtime burn: You pay 100% of their salary even during product planning lulls and release pauses.

Why an async workflow and one task at a time work in your favour.
Focused attention on your site without calendar interruptions or split focus. Here's why that gets your work shipped sooner.
One task in progress at a time
"Juggling many things at once is why simple tasks take weeks."
- Focus over context switching: research on task-switching suggests it can cost a large share of productive time. Working on one task at a time keeps attention on the thing that matters most to you.
- Predictable delivery: there's only one task in flight, with a visible countdown in your portal, so you rarely need to ask for a status update.
- Fewer shortcuts: focused work leaves room to do things properly instead of patching around them.
Async-first — everything in writing
"Focused engineering hours spent shipping your product instead of sitting on calendar syncs."
- Your fee goes into the work: time isn't lost to scheduling or status meetings, so every hour goes directly into code, architecture, and deployments.
- A written record: requests, comments, and pull requests live in your portal and repository, so decisions are clearly documented rather than lost in a call.
- No timezone friction: whether you're in San Francisco, London, or Bengaluru, nothing waits on a calendar slot. Add a request whenever it suits you.
Anatomy of a 48-Hour $99 Fix.
Real code diffs, database query optimizations, and security patches deployed to production. Zero guesswork — direct root-cause execution by a 20-year Senior Engineer.
Cart Fragments Bypass & Edge Query Caching
The Problem: WooCommerce's wc-cart-fragments was forcing an un-cacheable admin-ajax.php POST request on every single catalog visit, destroying server concurrency and spiking TTFB to nearly 2 seconds.
- // Flawed default: executes admin-ajax on every uncached catalog hit
- add_action('wp_enqueue_scripts', 'woocommerce_cart_fragments');
+ // SazM Fix: Dequeue script on catalog pages; read cart via localStorage
+ add_action('wp_enqueue_scripts', function() {
+ if (!is_cart() && !is_checkout()) {
+ wp_dequeue_script('wc-cart-fragments');
+ }
+ }, 99);Corrupted Autoload Transients & Postmeta Indexing
The Problem: Over 14MB of expired transients loaded into RAM on every PHP process in wp_options, while unindexed wp_postmeta scans across 2.4 million rows locked the database.
- -- Full-table scan across 2.4M rows on every product query
- SELECT meta_value FROM wp_postmeta WHERE post_id = ? AND meta_key = ?;
+ -- SazM Fix: Compound composite index + automated expired transient purge
+ ALTER TABLE wp_postmeta ADD INDEX idx_post_id_meta_key (post_id, meta_key);
+ DELETE FROM wp_options WHERE option_name LIKE '_transient_timeout%'
+ AND option_value < UNIX_TIMESTAMP();Zero-Downtime CVE Patch & Staging Verification
The Problem: Critical arbitrary file upload vulnerability in an abandoned plugin exposed the live server to remote shell injection. The client faced imminent storefront defacement or ransomware.
- // Insecure legacy handler: raw upload without nonce or mime verification
- move_uploaded_file($_FILES['upload']['tmp_name'], $destination);
+ // SazM Fix: Nonce verification + strict magic-byte MIME whitelist
+ check_admin_referer('secure_client_upload', '_sazm_nonce');
+ $allowed = ['image/jpeg', 'image/png', 'application/pdf'];
+ if (!in_array(mime_content_type($_FILES['upload']['tmp_name']), $allowed, true)) {
+ wp_die('Unauthorized file format rejected.', 403);

Twenty years of building and fixing production websites.
Anyone can copy and paste code. Knowing what actually works under real customer traffic — and what breaks during updates — takes decades of hands-on experience.
Experienced judgement, modern tools
Over two decades I've built and maintained more than 100 projects in the portfolio for clients — online stores, custom checkout flows, and web applications.
I use modern AI coding tools to work faster: drafting code and preparing changes quickly. I set the architecture, verify the safety of every line, and ensure every update arrives cleanly tested before it touches your live site.
- No junior hand-offs: the work is done directly by me, a senior developer.
- No subcontractors: no third-party agencies or strangers are ever given access to your site.
- Solid foundations: clean, readable code and fast-loading pages that don't bog down your site.

Frequently asked questions.
Straight answers about fixed-price fixes, the care plan, and the dedicated monthly development queue.
How can you deliver in 48 hours with zero meetings? ▾
Zero calendar friction. While traditional agencies spend 5 days coordinating calendars for a 45-minute discovery call, you describe your issue in our simple intake form with a URL, screenshot, or 2-minute Loom video. With 20+ years of hands-on production experience, I diagnose the root cause immediately, test safely in staging, and push working code to production. No calendar delays, no timezone friction, and zero meeting overhead.
What counts as 1 active task in the $999/mo retainer queue? ▾
A task is any distinct engineering deliverable achievable in 24–48 hours: a bug fix, an API webhook integration, a new UI component, a database query optimization, or an edge caching rule. If you request a large monolithic feature, I break it down into clean 24–48h milestone pull requests so you receive working software continuously. You can queue as many tasks as you want; they are executed sequentially in your priority order.
What if my issue is too complex for a $99 fix? ▾
If your project requires broader refactoring or custom architecture beyond a standard 48-hour fix, I will review your site and provide a guaranteed fixed-price quote in writing within 24 hours — free of charge and with zero sales calls. You decide whether to proceed with complete upfront certainty.
Will working on my website cause downtime or break my live store? ▾
No. Safety comes first. Every task begins with a full encrypted backup of your website files and database. Non-trivial fixes and updates are tested on an isolated staging environment before deploying to production, ensuring your live visitors and checkout transactions are never disrupted.
What if you can't fix my issue? Is there a guarantee? ▾
100% Money-Back Guarantee. If I cannot diagnose and solve the agreed root cause, or if the fix is technically impossible in your hosting setup, you receive a full 100% refund. You take zero financial risk.
How does the $999/mo retainer compare to a full-time hire or agency? ▾
A full-time senior US software engineer costs $150,000+ per year ($12,000+/mo) plus benefits, equity, recruiter fees, and notice periods — and you pay them even during product lulls. Traditional agencies charge $5,000–$15,000/mo minimums and hand your work to junior devs after hours of meetings. SazM gives you a dedicated 20-year senior engineer for $999/mo with zero meetings, 24–48h turnaround, and the freedom to pause or cancel anytime with one click.
Can I hire you for a single fix without signing up for a monthly plan? ▾
Yes! Most clients start with a single fixed-price fix — such as an urgent bug fix for $99 or a speed optimization for $199. You pay once, your issue is diagnosed and fixed within 48 hours, and there is zero ongoing commitment. Monthly plans are strictly optional for businesses with continuous backlogs.
How do I safely grant access to my website or server? ▾
You never have to share master passwords. You can invite me as a temporary WordPress administrator, a GitHub/GitLab collaborator, or grant restricted staging FTP/SSH access. Credentials can be shared through our encrypted intake form or password managers, and you can revoke access anytime once the work is delivered and verified.
Who actually does the work? Do you hand off to juniors or outsource? ▾
I do all the work personally — Saravana Bhava, a senior developer with 20+ years of experience in production (since Oct 2006) and 100+ projects in the portfolio. No junior developers, subcontractors, or third-party agencies. Read my Resume (PDF) for complete career history and credentials.
Who owns the code and intellectual property? ▾
You do. Work is committed to your own repository or installed on your site, and you own 100% of the code, designs, and assets created for you once the task is paid. See the Terms for details.
How do billing, payment, and invoicing work? ▾
You pay in USD through PayPal, which accepts major cards and PayPal balances. Fixed-price fixes are paid once upfront. Monthly plans bill automatically each month and can be paused from your client portal or cancelled anytime from your PayPal account or by emailing billing@sazm.in. A formal receipt/invoice is issued for each payment.
