Wavenet Software Solutions (Sweden-based startup — VoIP & Telecom) • Full time

Jan 2025 - Present • 1 yr 4 mos

I worked as a Full-Stack Developer at Wavenet Software Solutions, a Sweden-based VoIP and telecom startup, where I helped build a carrier-grade communication platform used for real-time calling, predictive dialing, and multi-tenant agent operations. My role went far beyond writing isolated features — I worked across the full product stack, owning core workflows end-to-end. On the backend, I contributed to scalable telephony microservices using NestJS, Prisma, and PostgreSQL, integrating deeply with Asterisk through ARI/AMI to support live call control, SIP trunking, call state tracking, and automated lead routing. I helped design APIs that powered real-time call flows, CRM interactions, and agent dashboards, ensuring low latency and high reliability under concurrent usage. On the frontend, I built and refined production Next.js interfaces used by internal teams and operators, including WebSocket-driven live dashboards for monitoring calls, agent activity, and system health. I focused heavily on performance, state consistency, and UX clarity in real-time environments where delays or inaccuracies directly affect operations. I collaborated closely with DevOps and QA to improve deployment stability, debug production issues, and optimize performance across services. This included assisting with CI/CD workflows, improving logging and observability, and supporting release hygiene for a fast-moving startup. Overall, I worked on real telecom infrastructure, not demos — solving reliability, scalability, and real-time data challenges that directly impact business operations. This experience makes me comfortable handling complex systems, integrating third-party services, and shipping production-ready solutions independently.

Payoneer • Full time

Jun 2024 - Dec 2024 • 6 mos

At Netraket, a Denmark-based startup, I worked as a full-stack engineer responsible for shipping real, production-grade features across frontend, backend, data, and automation layers. This was not task-based freelancing — I owned features end-to-end and worked directly with product and engineering stakeholders to move the platform forward. On the frontend, I built and refined complex React and Next.js (App Router) interfaces using TypeScript and Tailwind, focusing on clean UX, performance, and maintainable component architecture. I implemented dashboards, workflows, and data-heavy views that had to remain fast and responsive under real user load. On the backend, I developed Node.js and Express services exposing REST and GraphQL APIs, handling authentication, pagination, caching, and rate limiting. I designed and optimized MongoDB and PostgreSQL schemas, built ingestion and aggregation pipelines, and improved query performance across analytics views — cutting read latency by roughly 40%. I also integrated external systems, including WordPress (PHP/MySQL) plugins for cross-site analytics, and implemented AI-powered reporting workflows by wiring OpenAI and Gemini APIs with Python (pandas) data jobs. These pipelines were designed for reliability, traceability, and future scale — not demo usage. Beyond feature development, I owned CI/CD automation, release hygiene, and quality gates. I set up GitHub Actions pipelines, enforced test coverage, handled environment configuration, and ensured deployments were stable and repeatable. This role required autonomy, strong judgment, and the ability to ship without hand-holding — skills I bring to every client project.

software developer intern

Softmaque Consulting • Part time

Jul 2023 - Jul 2024 • 1 yr

At Softmaque Consulting, I worked as a Software Engineer Intern on a real enterprise-grade Defect Tracking and Workflow Management System used by internal teams. This was not a dummy internship; I actively contributed production code under senior engineer guidance and shipped features that impacted daily QA and release workflows. I implemented role-based UI modules using ASP.NET, jQuery, AJAX, and SQL Server, ensuring correct access control and consistent behavior across user roles. One of my core contributions was building an Excel bulk import pipeline with strong server-side validation, idempotency checks, and failure handling to safely process large datasets without data corruption. I also assisted in designing and refining workflow rules, notification triggers, and defect state transitions, improving system clarity and usability for testers and managers. Beyond coding, I authored detailed repro templates, helped standardize bug reporting formats, and compiled structured release notes for internal stakeholders. I regularly collaborated with developers, QA engineers, and product owners to debug edge cases, test fixes, and stabilize releases. My contributions helped reduce QA turnaround time by approximately 40% by streamlining defect intake, validation, and triage. This role strengthened my understanding of enterprise software discipline, data integrity, and collaborative development, and taught me how to ship reliable features inside an existing production system—experience I now bring to client projects with confidence.
