Gheyath Warrar

Profile

Eight years of building and shipping production software. Four of those years were spent on enterprise Java, Spring Boot and Angular systems at Meta-Level Software AG, owning delivery end to end — architecture, backend, frontend, automated testing, CI/CD and documentation.

Since then I have founded and engineered an AI-driven financial platform, and now work full time on LLM and agentic systems for companies in Europe and the Middle East: retrieval pipelines over client document sets, multi-agent workflows with tool and function calling, and the automation of processes that were previously manual.

I hold a B.Sc. in Finance and Banking alongside the engineering career. In practice that means I can sit in a conversation about a financial process and a conversation about the system that implements it, without a translator in between — which is why fintech, tax technology and regulated financial services are where I am most useful.

What I am brought in to do

The four problems clients and employers actually hire me for.

AI automation
Replace a manual, document-heavy process with a retrieval-backed LLM pipeline that runs unattended and can be audited afterwards.
Agentic systems
Design multi-step agents that call real tools and APIs — with the error handling, retries and guard rails that separate a demo from something you can put in front of customers.
Full-stack delivery
Take a system from architecture through backend, frontend, CI/CD and documentation. Java/Spring Boot and Python/FastAPI on the server; React, Next.js and Angular in front.
Financial domain
Build the above inside tax, banking and financial-services workflows, where the rules matter as much as the code.

Project list

Selected engagements, in the format that matters: objective, scope, what I did, what came out of it.

Open sourcePublic source 01Grade Tracker — academic records, reporting and AI-assisted workflows

Objective
Replace manual gradebook administration with an auditable system the people entering marks would actually use.
Period
2026
Role
Sole engineer — architecture, backend, frontend, CI, documentation
Stack
Python 3.12, FastAPI, Next.js 16, React 19, TypeScript (strict), SQLite (WAL)
Source
github.com/gwarrar/grade_tracker_new · MIT

What I did

  • Built a four-role authorisation model with a full audit trail over an academic records domain.
  • Enforced quality in CI rather than by convention: pytest with a coverage floor, ruff (pycodestyle, pyflakes, bandit, bugbear, pydocstyle), pyright, strict TypeScript, and an OpenAPI drift gate that fails the build when the spec and the code disagree.
  • Wrote the architecture, decision-record and security documentation alongside the code.

Result

  • 865 backend tests and 213 frontend tests — 1,078 in total.
  • 93% backend coverage, with an 85% floor enforced on every build.
  • Public and MIT-licensed: the code, the tests and the CI pipeline are all open to inspection.

ProductLive 02Syrian Exchange Pro — currency and financial market tracker

Objective
Give users in a volatile market a reliable, real-time view of exchange rates and financial data.
Period
Dec 2025 – present, actively maintained
Role
Sole engineer — architecture, backend, mobile apps, deployment
Stack
Python, React Native, REST API integrations, iOS and Android release pipelines

What I did

  • Built the data ingestion layer aggregating multiple rate sources with reconciliation between them.
  • Developed the cross-platform mobile client and shipped it through both app store review processes.
  • Set up the release and monitoring pipeline so updates ship without manual steps.

Result

Add: user or download numbers, uptime, number of rate sources.

AI automationDelivered 03Cultural Lights — removing administrative bottlenecks with AI

Objective
Identify where AI and automation could remove administrative and operational load, then implement and embed it.
Period
Nov 2023 – Sep 2025
Role
Consultant and implementing engineer
Stack
LLM tooling, n8n, Make.com, API orchestration

What I did

  • Audited existing administrative processes with leadership and scoped which were worth automating.
  • Built the resulting automated workflows and integrated them with the tools already in use.
  • Ran the training programme that moved non-technical staff onto the new workflows, so the change stuck after I left.

Result

  • A 22-month engagement — extended repeatedly rather than ending at the first deliverable.

Add: hours saved per week, number of processes automated, people trained.

FounderBuilt & launched 04TaxBox — AI-driven tax and financial services for expatriates

Objective
Make German tax and financial services navigable for expatriates who do not speak the language or the system.
Period
Nov 2022 – Nov 2023
Role
Founder, lead engineer and CEO — led the development team
Stack
Full-stack platform with AI-assisted document and financial workflows

What I did

  • Designed the architecture and built the platform across backend, frontend and deployment.
  • Led the development team and owned the delivery process from concept to production.
  • Handled the regulatory and domain complexity of German tax directly, drawing on the finance degree.

Result

  • Selected for the Hogan Lovells BaSE 2022 social enterprise showcase.

Add: team size, users or signups, funding raised, time from zero to live.

Enterprise engineering4-year tenure 05Meta-Level Software AG — enterprise application development

Objective
Build and maintain scalable enterprise applications for business clients.
Period
Sep 2018 – Nov 2022 · 4 years 2 months
Role
Full-Stack Software Developer
Stack
Java, Spring Boot, Angular, Docker, Git, Jira, CI/CD

What I did

  • Owned features end to end: system architecture, backend and frontend development, automated testing, CI/CD deployment and technical documentation.
  • Worked inside Agile delivery teams across a four-year tenure on the same product line.

Result

  • Four years of continuous delivery on production enterprise systems — the foundation the AI work is built on.

Add: team size, who the systems served, scale, a migration or system you led.

ProductLive 06Radius Trip — map-based travel search and planning

Objective
Let travellers search by what is actually reachable within a radius, rather than by destination name.
Period
Feb 2026 – present
Role
Sole engineer
Stack
React Native, geospatial search, LLM integration

What I did

  • Built the geospatial radius search and itinerary planning logic, and the cross-platform client on top of it.
  • Deployed and maintained on a custom domain — radiustrip.com

Result

  • Live and publicly accessible.

Add: users, trips planned, load time (currently ~2.9s — worth optimising, recruiters click this).

Own buildLive 07Retrieval-backed agent and multi-model sandbox

Objective
Demonstrate a production agent rather than describe one.
Period
2026
Role
Sole engineer
Stack
Cloudflare Workers, server-sent-event streaming, multi-provider model routing

What I did

  • Built an edge-deployed agent with streaming responses, grounded strictly in a fixed knowledge base and hardened against prompt injection.
  • Added a live code-generation sandbox and routing across several model providers — resume-1g3.pages.dev

Result

  • Running below, in section “Ask my agent”. Same stack I would bring to your team.

Experience

Eight unbroken years of engineering, drawn to scale.
