I build AI agents, web & mobile apps, and the API integrations that make them work in production.
10 years of software engineering: web apps, mobile apps and the back ends behind them. The last few shipping LLM systems into real business software. Not a chatbot that answers and stops.
The 24-hour read
Pick a problem. This is the shape of the read I'd send back within 24 hours.
RE: Invoices & documents
Pre-written · the real one follows a call
RE: Invoices & documents
- Approach
- Read the invoice, check it against your own systems, do the work: a bill in QuickBooks, a ticket in the helpdesk, a line in Slack.
- What breaks
- 429s, 5xx, timeouts — so retry with exponential backoff, duplicate and reconciliation checks, an approval threshold, and a replayable event log.
- Not AI
- I tell you when AI is the wrong tool. Sometimes a 40-line script beats an LLM: cheaper, faster, deterministic.
RE: CRM ↔ accounting sync
- Approach
- Two systems never designed to talk: webhooks, OAuth flows, rate-limited endpoints. Refunds, partial payments, and reconciliation handled automatically.
- What breaks
- Rate-limited endpoints and OAuth flows. Error handling, logging, and monitoring from day one, not after something breaks.
- Not AI
- Sometimes a 40-line script beats an LLM: cheaper, faster, deterministic. I say so even when the AI version would bill more hours.
- Proof
- Stripe ↔ QuickBooks sync for a logistics company. Has reconciled cleanly since launch without manual fixes.
RE: An assistant on your own data
- Approach
- Trained on your own data — Slack, Notion, Google Workspace, or your database — and answering with sources, so output is verifiable instead of confidently wrong.
- What breaks
- Confidently wrong answers. Sources on every answer make them verifiable; error handling, logging, and monitoring from day one, not after something breaks.
- Not AI
- I tell you when AI is the wrong tool. I say so even when the AI version would bill more hours.
- Tools
- Anthropic API · OpenAI API · open models · LangChain · LlamaIndex · RAG · Pinecone · Supabase pgvector · Chroma · evals
RE: An undocumented or legacy API
- Approach
- Third-party, undocumented, and legacy SOAP APIs: webhooks, OAuth flows, rate-limited endpoints. Half my career. Built to survive production, not just a demo.
- What breaks
- Rate-limited endpoints, OAuth flows, SOAP. Error handling, logging, and monitoring from day one, not after something breaks.
- Not AI
- Sometimes a 40-line script beats an LLM: cheaper, faster, deterministic. Either way, code you can hand to another developer: documented, structured, yours.
- Tools
- REST · GraphQL · webhooks · OAuth2 · SOAP · Python (FastAPI, Django) · Node.js (Express, NestJS) · PHP/Laravel · .NET/C#
RE: A web or mobile app
- Approach
- Screens and data first, then the build: React or Next.js on the web, React Native or Flutter for iOS and Android from one codebase, a Python or Node API shared by both. Ten years of shipping this.
- What breaks
- Auth edge cases, slow networks, offline states, app-store review. So milestone one is a working skeleton on a real device, with tests, CI and crash reporting from day one.
- Not AI
- Most of an app is not AI. I tell you which small part benefits from a model and build the rest as plain, fast, maintainable software you own.
- Proof
- GoGstaad: food ordering and taxi booking for Gstaad, Switzerland. Customer app on iOS and Android, a driver app, and the backend behind them.
- Tools
- React · Next.js · TypeScript · React Native · Flutter · Python (FastAPI) · Node.js · Postgres · Supabase · Stripe · CI/CD
- Timeline & cost
- Realistic estimates. Fixed scope, clear milestones, no surprise invoices.

Hello, I'm Malik.
The engineer you hand the hard part to.
I've spent ten years building software for people who need it to work on Monday morning, not just in the demo. More than two hundred and ten projects with a 5.0 average rating on Fiverr, and enough production incidents to know what actually matters: honest scoping, boring reliability, and code you still own when I'm gone.
For the last few years that has meant putting LLMs to work inside real business systems — agents that read documents and take actions, assistants that answer with sources, integrations between tools that were never meant to talk. I like the unglamorous parts: retries, rate limits, logging, the monitoring that keeps a system running while you sleep.
I work from Karachi with clients in the US, UK, EU, Australia and the Middle East, overlapping US mornings and EU afternoons. You'll get written updates without asking, a realistic estimate, and a straight answer — including "you don't need AI for this" when that's the truth.
- 01
Honest scoping
A short scoping call before any estimate. I would rather tell you the project is simpler than you thought than take a bloated budget.
- 02
Boring reliability
Error handling, logging, and monitoring from day one, not after something breaks. Realistic estimates, fixed scope, clear milestones, no surprise invoices.
- 03
Code you still own
Documented, structured, yours. No lock-in, no black box, and support after delivery — I don't disappear at handover.
Work4 projects
Work
Two you can open. Two I can only describe: that client work stays private, so I show the shape of it instead.
01 AI operations agent live
Relay
Paper in. Actions out.
An AI operations agent that reads supplier invoices and customer emails, checks them against the company's own systems, and does the work: bills in QuickBooks, tickets in the helpdesk, a line in Slack.
- Role
- Design, backend and frontend. Solo project.
- Stack
- Python · FastAPI · LLM tool use · SSE · vanilla JS · pytest · live demo on Cloudflare Workers AI
- Guardrails
-
- Six tools with strict JSON schemas
- Duplicate and reconciliation checks
- Approval threshold
- Retry with exponential backoff for 429 / 5xx / timeouts
- Event log streamed over SSE — replayable, testable without a network
02 Client work · Gstaad, Switzerland live
GoGstaad
A ride or a meal. One app, one account.
The taxi and food delivery app for Gstaad and the Saanenland: a customer app for iOS and Android, a driver app, and the backend that runs both. Order from local restaurants and follow the delivery, or book a taxi with the fare shown before you confirm, schedule the early airport run the night before, and pay by card or TWINT.
- Role
- Customer app, driver app and the backend behind them.
- Scope
-
- Restaurant ordering with live order tracking
- Taxi booking: fare up front, rides scheduled in advance, the driver tracked on the map
- Airport and city transfers to Geneva, Zurich, Bern and Basel
- Card and TWINT payment in the app
- Driver app: jobs, shifts and zones, navigation, earnings and payouts
- German, French and English

How I workFrom first message to handover
How I work
I tell you when AI is the wrong tool. Sometimes a 40-line script beats an LLM: cheaper, faster, deterministic. I say so even when the AI version would bill more hours.
01 First reply · within 24 hours
An honest read
Send me the problem, even roughly. Within 24 hours you get an honest read on approach, timeline, and cost. If I am not the right person for it, I will tell you that too.
02 Scoping call · short, first
Simpler than you thought
A short call before any estimate. I would rather tell you the project is simpler than you thought than take a bloated budget. Sometimes a 40-line script beats an LLM.
03 Scope & milestones · fixed, written
No surprise invoices
Fixed scope, clear milestones, realistic estimates. I have been wrong enough times to know how long things take, so the plan is one you can hold me to.
04 Build · with written updates
You never have to ask
Regular written updates, so you always know the status. Error handling, logging, and monitoring from day one, not after something breaks.
05 Handover & after · support included
Code that stays yours
Documented, structured, yours: code you can hand to another developer, no lock-in, no black box. Support after delivery. I do not disappear at handover.
