Hi there, I’m a senior software engineer based in Auckland, New Zealand, with over seven years of experience building reliable, scalable backend systems and integration solutions. I’m excited to apply through Twine as I enjoy working on flexible, project-based engagements where I can quickly add value and collaborate with diverse teams. My background is primarily in backend development and integrations, with strong hands-on experience in Java (Spring Boot), Python, RESTful APIs, SQL, microservices, and event-driven architectures. I’ve worked on a wide range of projects—from financial systems and enterprise platforms to API-driven products—where performance, security, and clean system design were critical. I’m comfortable owning work end-to-end, including system design, development, debugging, testing, and deployment. I’ve also worked extensively with CI/CD pipelines, Docker-based deployments, Agile workflows, and cross-functional collaboration with product and non-technical stakeholders. This makes me well-suited to freelance environments where clarity, accountability, and delivery matter. In addition to traditional backend work, I have experience integrating AI-powered components and automation where they add real business value. I enjoy solving complex problems, adapting quickly to new domains, and delivering maintainable, well-documented solutions that clients can confidently build on. I’m currently based in New Zealand and hold a student visa with full working rights, allowing me to take on contract and freelance work without restrictions. I’m available for remote projects and can work independently or as part of a distributed team. I’d love the opportunity to collaborate on projects through Twine and contribute my technical expertise to meaningful, well-crafted products. Best regards, Bisma Ayaz
