You will get Clean, Scalable Backend APIs Built with Modern Frameworks
Project details
I build clean, secure, and scalable backend systems using Laravel, Node.js (Express/Nest), FastAPI, and Spring Boot.
My focus is simple: readable code, proper validation, secure APIs, and systems that don’t break when you scale.
FinTech experience is available if required, but not forced.

About M. Atiq
FinTech Engineer | Payments, Card Issuing & PSP
Islamabad, Pakistan - 12:29 pm local time
issuing, acquiring, ISO 8583, digital wallets, and PCI DSS Level-1
platforms. 6+ years building production systems that move real money
across MENA, the UAE, and global markets.
At VaultsPay (Dubai), I lead a 30+ person engineering org delivering a
PCI DSS Level-1 acquiring and issuing platform. I took the platform's
uptime from 84% to 96%, shipped a configurable rules engine that lets
non-technical teams control routing, fees, fraud, and compliance, and
built the digital wallet, ledger, and reconciliation layers that PSPs
and acquirers integrate against.
I also founded Numeriv, an AI-powered personal finance platform, where
I designed a multi-bank statement normalisation pipeline supporting
heterogeneous formats across global markets — so I understand the
commercial side of FinTech, not just the code.
What I deliver:
âś… Payment Processing & Switching
ISO 8583, card schemes (Visa / Mastercard / Mada / GCCNet),
authorisation, clearing, settlement, chargebacks, scheme certification
âś… Card Issuing & Acquiring Platforms
Merchant onboarding, terminal management, virtual & physical cards,
3DS, tokenisation, fee engines, markup rules
âś… Digital Wallets & Core Banking
Multi-currency ledgers, P2P transfers, top-ups, IBAN generation
(UAE / KSA / PK / BH, ISO 13616-1 compliant), reconciliation
âś… Backend Architecture
Java / Spring Boot, Python / Django, Node.js, PostgreSQL, Kafka,
Redis, microservices, event-driven systems
âś… Cloud & DevOps
AWS (KMS, ECS, RDS, multi-region), Docker, Kubernetes, CI/CD,
Hibernate / JPA tuning, production incident response
âś… Compliance & Security
PCI DSS Level-1, AML/KYC pipelines, SAR/STR workflows, audit-ready
transaction reporting, MENA regulatory landscape (CBUAE, SAMA)
Selected outcomes:
- Architected VaultsPay PCS — a Payment Card Services SaaS now serving
MENA acquirers and PSPs.
- Scaled VaultsPay Acquiring from MVP to Tier-1 PCI DSS provider.
- Cut trading-engine latency 60% on a regulated crypto exchange
(Burency) through targeted caching and query redesign.
- Built the banking engine for a VC platform handling investor
subscriptions and periodic NAV calculations.
- Diagnosed and resolved an AWS KMS cross-region outage on a live
auth service without data loss.
I work best with:
- FinTech founders building MVPs that need to be audit-ready from day one
- PSPs and acquirers needing scheme certification, ISO 8583 work, or
ledger redesign
- Teams inheriting a legacy payments codebase and needing a senior
hand to stabilise, refactor, and document it
