At FASSET, I integrate payment rails and financial infrastructure, including virtual IBAN pay-ins, local-currency payouts, ACH accounts, and stablecoin settlement. I also built SWIFT transfer and deposit flows over Keel and delivered Rain card issuing with spend-limit controls.
I hardened money-movement webhook handling by addressing a replay vulnerability and missing transaction wrapping. I also cut card-list API latency by 30% by removing repeated lookups, parallelizing calls, and adding Redis caching.
At AKSA-SDS, I developed backend microservices for JazzCash, including features for savings plans, group expenses, BNPL, and investments. I integrated Bookme and KTrade into the super-app and worked on financial transaction integrity in a high-concurrency environment.
At BAKHABAR KISSAN, I developed APIs for a distributed monolith serving 5M+ farmers and contributed to a product-advisory feature and LLM-based crop disease identification. Earlier at STACKONE, I engineered AWS-backed APIs and microservices and improved resilience through CloudWatch alert and CI/CD pipeline optimizations.
