The hardest part wasn't building the game. It was making it PLAYABLE. 🎮
While building Shadow Heist, I hit errors that broke the game, interrupted missions, and forced me back into debugging more times than I expected.
But that's where the real development happened.
I fixed the issues, tested the gameplay, pushed through the final mission, and turned the idea into something people can actually play.
Build. Break. Debug. Fix. Repeat.
That's what development really looks like behind the screen.

Toughest for me was a rich text editor that swallowed the first keystroke when it took focus. No error, no crash, the text just published with the first letter missing. It stayed hidden a while precisely because nothing failed loudly. Now I read the field back before submitting....
Built the architecture behind Dervale, a multi-tenant AI gateway designed to give applications one unified API for working with multiple AI providers.
The platform is built around a Java + Spring Boot backend with:
• OpenAI-compatible API access
• Multi-provider routing and fallback
• JWT authentication, API keys, workspaces and RBAC
• Usage metering, budgets, quotas and rate limiting
• PostgreSQL + Redis for persistent and runtime data
• Request, audit and security logging
• Cost, token and latency observability
• Response caching and guardrails
• Billing and account controls
The goal was to make AI infrastructure easier to operate: one gateway for routing, governance, observability and access control instead of implementing each provider independently.
This architecture was designed with maintainability, tenant isolation and future provider expansion in mind.
Stack: Java, Spring Boot, React, PostgreSQL, Redis, Docker
Open to new work — full-time or contract.
I'm a full-stack engineer with 6+ years of experience, working with TypeScript across the stack. Most of that time has been spent embedded in a small number of products for years at a time, rather than rotating between short gigs — which means I've owned things long enough to live with my own decisions.
What I build:
AI/LLM products — tool-calling agent workflows that act on results autonomously, retrieval-grounded generation over large corpora, structured outputs with validation, and evaluation against real outcomes. Built in-house, with the model provider behind a service boundary so routing stays swappable.
Payments — Stripe Connect and Subscriptions in production: recurring billing, plan changes, usage-based charges, marketplace payouts, and webhook-driven reconciliation so the ledger stays accurate when events arrive late, twice, or out of order.
Integrations — 15+ third-party APIs including Amazon Seller/Vendor Central, Google, and Microsoft Graph behind one normalized interface, cutting integration time by ~40%.
Real-time & scale — WebSocket services maintaining consistent state for thousands of concurrent users, with reconnection and out-of-order delivery handled explicitly.
Stack: TypeScript · React · Next.js · Node/Express · PostgreSQL · Redis · AWS · Docker · CI/CD. Claude Code and MCP tooling are part of my daily workflow.
If you're shipping something early-stage and need someone who can take a feature from schema to production without a handoff, my DMs are open.
good luck in your job search Ali
