Olajide is very easy to communicate with. He's availability is outstanding. He is also very easy to work with, and obviously knows how to code. While we weren't able to complete all the tasks, he did get most of it accomplished. I would not hesitate to hire him again.

Olajide delivered an outstanding enterprise readiness assessment for our Electron desktop application. This wasn't generic consulting - he approached the codebase like an IT security gatekeeper evaluating a $10K/year software purchase. What Made This Valuable: ✅ Enterprise Perspective - He identified what would kill a deal (unsigned installer, no error monitoring, installer limitations) vs. what's just "nice to have" ✅ Specific & Actionable - Not vague advice. He cited exact files/line numbers, recommended specific tools (DigiCert EV over Sectigo, Sentry over alternatives) with clear reasoning ✅ Priority Ordering - Broke recommendations into Critical/High/Medium so I knew what to fix first ✅ Real-World Testing - Provided concrete test scenarios (domain-joined VMs, AV/EDR compatibility, locked-down workstations) that enterprise IT actually cares about ✅ Fast Delivery - Delivered comprehensive written report in 20 hours as promised The assessment covered: Architecture validation (confirmed solid patterns) Code signing strategy (provider selection, workflow, IT requirements) Error monitoring implementation (privacy-safe config for compliance context) Windows deployment gotchas (SmartScreen, Defender, AppData permissions) Testing strategy for IT evaluation MSI vs NSIS considerations for Group Policy environments Bottom Line: If you're building B2B/enterprise software and need to understand what will make IT departments reject your application, Olajide is your person. He thinks like the buyer's gatekeeper, not just a developer. Worth every penny for avoiding failed pilot deployments. Highly recommended for anyone shipping production Windows applications to enterprise customers.

Olajide is an exceptional code mentor. What sets him apart is his unique combination of deep technical expertise and a truly patient, structured teaching style. It's clear he's motivated by his impact, not by fees, and he is genuinely committed to your success. He goes the extra mile, offering practical, actionable feedback and clear explanations to help you get your project across the finish line. :-)
