Computer Engineer that highly motivated to learn about popular fields of computer engineering especially in web and mobile application development. Also has constant enthusiasm for new technologies.
- Architected and maintained a high-concurrency microservices ecosystem for Getir Marketplace, supporting 375k+ daily orders and handling millions of API requests with 99.9% availability. - Orchestrated the lifecycle and scalability of 65+ microservices across 3 core domains (Food, Locals, Water), ensuring seamless integration of complex business requirements into a distributed architecture. - Drove end-to-end latency optimization across critical Checkout backend endpoints, achieving measurable improvements in avg, p95, and p99 response times; refactored system that delivered a 35-40% performance gain, later shared and adopted as best practice company-wide. - Led a large-scale legacy decommissioning initiative, retiring microservices along with their infrastructure dependencies, delivering substantial operational simplification and an annual cost saving of ~$155k - Led the architectural migration from RabbitMQ to Kafka, identifying which system components and message flows were best suited for an event-streaming model and driving the technical transition end-to-end; - Developed cost-effective in-house alternatives to expensive 3rd-party vendors, including a custom Chatbot and Scrum Poker Application (as an initiative). Successfully migrated from a $600k/year outsourced solution to a serverless architecture running under $30/year. - Designed and built the Group Basket/Order flow from scratch as a pioneer in local market, enabling multiple clients to collaboratively place a single order through one shared, real-time synchronized basket. - Spearheaded a company-wide observability transformation with standardized alarms and a unified dashboard across all microservices. Also built infrastructure-level observability from the ground up, including messaging flows (Kafka/SQS) and adopted this practices across the company.
- Led a critical migration from Synchronous API calls to an Asynchronous Event-Driven Architecture, significantly reducing system coupling and improving fault tolerance of application hot paths even under peak traffic loads. - Built and launched the backend for the Getirİşyerim B2B platform, integrating a robust BNPL (Buy Now Pay Later) infrastructure that unlocked a major new revenue stream and significantly increased the purchasing power of restaurant partners. - Revamped the IVR (Interactive Voice Response) system to automate status notifications, reducing missed orders and increasing successful order fulfillment rates by 25% - Owned the mission-critical POS Integration flow handling 70% of total order volume; optimized data consistency and transmission reliability with diverse 3rd-party logistics and restaurant partners. - Initiate E2E backend test automation via building scaffold infrastructure, also significantly increasing automated test coverage across services to strengthen release confidence and reduce regression risk.
- Built a modular SaaS platform “Ming” from scratch, architecting a scalable multi-tenant system featuring 16+ core modules. (Announcements, Events, Surveys, Payroll, In-Company Social Media, Marketplace, Feedbacks etc) All content can be managed from a specific "Audience Filter" secured by Attribute-Based Access Control (ABAC). - Delivered end-to-end development for Web, Mobile, and Admin panels using a unified stack (NestJS, React, React Native, MongoDB), leveraging Redis for caching and Kafka for asynchronous processing. - Successfully launched the MVP and onboarded the first enterprise clients, establishing robust B2B integrations and a flexible product bundling infrastructure.
- Contributed to “Talent Interview”, a real-time technical assessment platform similar to HackerRank and Codility, designed to streamline remote developer hiring and automated evaluation at scale. - Architected a high-throughput backend using Java Spring Boot and MySQL. - Integrated Apache Kafka for reliable asynchronous event streaming like queuing concurrent code execution requests for ensuring decoupled, fault-tolerant processing of student submissions during peak traffic and Redis for low-latency caching and session management. - Streamlined DevOps workflows by orchestrating automated CI/CD pipelines via Jenkins and managing containerized deployments to ensure high availability on Huawei Cloud.
- Engineered “HireIO” as a Full-Stack Developer, building a cloud-native, multi-tenant Applicant Tracking System (ATS) using React, NestJS, and MongoDB to rival industry standards like Greenhouse, Lever, and Workable. - Architected a secure multi-tenant infrastructure, implementing complex backend security protocols with RBAC/ABAC for strict data isolation. - Developed responsive UIs using React, including a comprehensive administrative management panel and a public-facing job posting portal that enables companies to publish listings under their own unique subdomains. - Built a customizable workflow management engine with interactive drag-and-drop features, enabling companies to tailor hiring pipelines with seamless state synchronization across the full stack. - Integrated an intelligent "Applicant Match Rate" algorithm and “Automated CV Parsing” features to streamline candidate applications and ranking systems, significantly reducing time-to-hire.
- Owned the mobile development of the TEDU App from scratch, the official mobile platform for TED University's student ecosystem, built with Flutter, Firebase Auth, and Google Cloud Functions. - Built TEDUClass, an automated course scheduling tool that generates all possible timetable combinations based on selected course codes and desired number of free days, allowing students to instantly import their chosen schedule. - Delivered a real-time push notification system for announcements and campus events, and seamless SSO authentication via TEDUPass, eliminating the need for manual registration.
- RF and Simulation Systems Intern that worked on Web Ontology & Semantic Web - Developed a dual-interface (GUI and CLI) adapter tool in Java that automated the conversion of proprietary JSON files into RDF-XML format compatible with Protégé, enabling the automatic generation of simulation environment object classes, properties, data types (both default and user-defined), and relations — eliminating manual ontology construction by leveraging; - OWL API, Apache Jena API and Ontology (ONT) API - Java, JavaFX launch4j
