Experience
AI-powered Document Engine for Financial Verification
Compared to every major vendor we benchmarked, this engine outperformed them in speed, accuracy, and reliability, making it, in my view, the most robust solution on the market today. It now serves as the core of VeriFast’s verification platform, which is used by enterprise clients for onboarding and compliance workflows.
AI Name Matching Engine for Identity Validation
The engine uses rule-based logic combined with string similarity, token collapse, common nickname lookups, and cultural pattern handling. It’s been especially effective in KYC and identity-checking workflows where false negatives can block legitimate users, and false positives can raise red flags. It’s now part of a broader verification pipeline, helping platforms resolve ambiguous user submissions without needing manual review.
Lightweight API Toolkit for Laravel Projects
This system allows me (and teams I’ve mentored) to spin up production-grade APIs in hours, not days, without relying on bloated starter kits or overengineered frameworks. Each component is fully decoupled, testable, and designed for rapid extension across MVPs, internal tools, and client-facing products. It’s now part of my standard build stack and has significantly accelerated delivery time across dozens of projects.
SPA Prerendering and Route Validation via AWS Lambda
To solve this, I built a Lambda-based prerendering service that validates requested routes against the actual structure of the SPA and returns proper responses: a pre-rendered HTML snapshot for valid routes, or a true 404 for anything that doesn’t exist. It hooks into the deployment pipeline, crawls the app to capture all navigable routes, and stores renderable snapshots that are served at the edge via CloudFront or equivalent.
The result is a fully static SPA that behaves like a server-rendered app from the outside - proper status codes, crawlable content, and vastly improved SEO without requiring SSR frameworks or custom server hosting. It’s lightweight, infrastructure-agnostic, and production-proven.
Modular Laravel Extension for Scalable Architecture
With this extension, every module behaves exactly like the native app directory, meaning each one has its own models, controllers, views, and routes, fully self-contained and independently manageable. This makes large-scale codebases far easier to organize, extend, and test, especially in fast-moving environments or multi-team setups.
Initially created as an extension to both Lumen and Laravel for API-first development, the framework has since evolved into a production-ready system I use across nearly every project I touch. It eliminates set up bloat, reduces architectural debt, and enforces best practices from the moment a project begins. I’ve used this system across social networks, CRM platforms, and SaaS applications, and it’s been instrumental in helping teams scale fast without sacrificing clarity or quality.
Modular PHP Framework for Scalable Web Systems
As my projects scaled, I needed something more structured and maintainable, so I developed a modular framework tailored for scalable web and API development. It included its own routing engine, configuration system, ORM-style query builder, middleware stack, and CLI tooling.
I used and refined this framework across dozens of client projects over five years. By the time I moved to Laravel, I had already implemented many of the same core concepts, just with my own hands. The experience taught me when to build, when to adopt, and how to architect for long-term resilience. It also shaped how I approach systems today: with clear intent, scalability, and full-stack awareness.
Modular JavaScript Loader (JavaScript API)
So, I developed a centralized system to register, load, and version my JavaScript modules on demand. Instead of hardcoding dozens of
Intelligent Automated Outreach System
The engine worked by analyzing in-app activity patterns, user demographics, and interaction history, then using that data to generate real-time outreach across multiple channels. It was designed to feel personal but remain automated, avoiding the kind of blunt, intrusive tactics that typically lead to churn or drop-off.
Within days of deploying the system, we saw a sharp increase in organic engagement and onboarding velocity. The user acquisition rate nearly doubled overnight, and retention saw measurable gains due to the relevance of the outreach. The system also significantly reduced manual marketing overhead and became a key part of our growth stack. It wasn’t just a campaign tool, it was a fully integrated engagement layer built to scale.
Smart Query Parser for Laravel APIs
As the system matured, I integrated smart eager loading, automatic relationship resolution, and intelligent defaults to avoid the N+1 problem without over-fetching. The parser also supports modular configuration and can be dropped into any Laravel project with minimal set up.
While initially designed to streamline admin and reporting APIs, it quickly became a core part of my back-end toolkit, reducing duplication, enforcing consistency across endpoints, and significantly speeding up internal tooling builds. In many ways, it gave my APIs 90% of the power of GraphQL, with none of the overhead.
Smart Contact Sync Engine for Growth
The system synced the user’s contacts with the back end in real time, then applied intelligent matching based on phone number patterns, previous user behavior, time zones, and metadata. It could trigger targeted invites, smart nudges, and preemptive onboarding workflows - without feeling intrusive or spammy. What made it especially effective was its subtlety. It didn’t blast everyone in the contact book. It picked who to reach, when, and how, maximizing conversion while maintaining user trust. Within a few days of rollout, the app’s invite-driven growth rate surged, and we saw a measurable lift in activation metrics.
I’ve since adapted this engine for several other applications - each time tweaking the logic for the audience. Still, the core strategy remains one of the most efficient, technically satisfying growth solutions I’ve implemented.
Resilient Web Crawlers for Structured Data Extraction
Over time, I developed a toolkit of resilient crawler patterns - complete with retry logic, rate-limiting, user-agent spoofing, proxy rotation, and DOM-based parsing - to ensure reliable extraction across varying environments. These scripts weren’t just throwaway utilities; they became core data pipelines used internally to automate reporting, support sales ops, and populate back-office tooling.
In several cases, the data being scraped was locked behind JS-rendered interfaces, requiring headless browser control and asynchronous resolution strategies to extract meaningful content. I’ve also built schedulers, storage engines, and diff-checking logic only to sync changes rather than entire datasets. It’s a technically messy space, but I’ve built systems that handle the chaos quietly and consistently, exactly how automation should.
Early Viral Platform for Peer Content Sharing
The website was designed and built entirely by me, with real-time data feeds, dynamic user moderation, and tools to detect abuse and protect user anonymity. It was hosted on minimal infrastructure but scaled gracefully due to lean code and efficient caching strategies. I learned more in those first few weeks of firefighting, scaling issues, and keeping servers alive than any tutorial could’ve taught me.
This project didn’t just go viral; it gave me my first hands-on lesson in infrastructure under pressure, UX at scale, and the power of momentum when a product truly resonates with its audience.
