Real problems. Real solutions.

Anonymous stories from real clients. The problems and outcomes are exactly as they happened.

Bug FixOnline Store·Same day

Checkout was charging customers twice

The situation: Checkout was broken. Customers would pay, see an error, try again, and get charged twice. The agency that built the site wasn't responding. Angry emails coming in daily.

The outcome: Race condition in the payment callback. Fixed it, added proper error handling. No more double charges.

Two weeks of angry customers, fixed in one afternoon.

Performance FixB2B Software·1 day

Dashboard took 10+ seconds to load

The situation: Main dashboard had become unusably slow. Enterprise clients threatening to cancel. The freelancer who built the app had moved on. Throwing more server resources at it didn't help.

The outcome: Found a single query scanning millions of rows without an index. Added proper indexing. Dashboard now loads in under a second.

We thought we'd need to rebuild everything. Turns out it was fixable in a day.

Code RescueEducation Startup·4 days

Developer vanished mid-project

The situation: Developer stopped responding. App was half-finished. No access to code or hosting. Three weeks from planned launch with investors waiting.

The outcome: Recovered access to everything — code, databases, hosting. Documented what existed and what was missing. Launched 5 weeks later with a new developer.

I thought I'd lost everything. He saved my startup.

Code ReviewSaaS Acquisition·2 days

Due diligence before buying a software business

The situation: About to close on a $40K software acquisition. Seller couldn't answer basic technical questions. Needed an honest assessment before signing.

The outcome: Found three serious problems — security vulnerability, deprecated API dependency, and undisclosed technical debt. Negotiated $8K off and got critical issues fixed before closing.

Worth every penny. I almost bought a ticking time bomb.

API IntegrationMarketplace·2 days

Marketplace needed to pay sellers automatically

The situation: Built a marketplace with no-code tools but hit a wall with Stripe Connect. Needed automatic payouts to sellers. Two weeks behind schedule, sellers getting impatient.

The outcome: Set up Stripe Connect with onboarding flow, automatic payouts, and webhook handling. 200+ sellers onboarded first month, zero payment issues.

We were dreading this. He made it look easy.

Code ReviewFintech·1 day

Investor required independent code review

The situation: Two weeks from launch. Lead investor wanted an independent technical review. Non-technical founders needed findings explained in plain English.

The outcome: Found two critical security issues. Fixed them before going live. Clear report the co-founder could understand. Investor signed off.

He explained everything so clearly that even I understood the risks.

Bug FixE-commerce·3 hours

Site crashed during Black Friday sale

The situation: Saturday morning. Website crashed during Black Friday sale. Agency that built it wasn't answering. Every hour of downtime costing thousands.

The outcome: Database connection pool exhausted under load. Increased limits, added connection recycling. Back online in 3 hours. Ended up being their best sales day ever.

He dropped everything on a Saturday and saved our biggest sale of the year.

Code RescueHealthcare·3 days

Inherited a codebase with zero documentation

The situation: Custom software built by a contractor years ago. Contractor long gone, no documentation. Needed to add features for compliance but afraid to touch anything.

The outcome: Mapped out the entire system — what it did, how it worked, what was risky to change. Delivered documentation and prioritized fix list.

Finally understand what we're working with. The documentation alone saved us weeks.

Feature DevelopmentHR Software·2 days

Customers wanted data exports

The situation: Weekly support tickets asking for data export. Founder built the original product but no time to add features while running the business.

The outcome: Built export feature matching existing UI patterns. CSV, PDF, scheduled exports. Support tickets about exports dropped 80%.

Fits perfectly with our existing app. You'd think our team built it.

Bug FixProject Management SaaS·3 days

Pricing changes kept breaking billing

The situation: Every time they tried to update pricing, something broke. Billing logic scattered across the codebase by the original dev shop. Stuck on outdated pricing.

The outcome: Consolidated all pricing logic, added tests. Launched new pricing tier the next month with zero issues.

We can finally update pricing without holding our breath.
