Full Stack Developer Needed to Fix Issues in Existing Project Fix
Kaveesha did an outstanding job. He quickly understood the existing application and the issues that needed to be resolved, then completed the work within 24 hours.
He was highly responsive, technically capable and extremely efficient. The work was completed exactly as required, with clear communication throughout. His ability to diagnose and resolve problems so quickly gave me great confidence in both his technical expertise and his reliability.
I would have no hesitation in working with Kaveesha again and highly recommend him to anyone looking for a skilled, dependable and fast full-stack developer.

Job Success
Weeraketiya, Sri Lanka - 9:10 am local time
In addition to application development, I bring strong DevOps expertise in AWS, Azure, GCP, Kubernetes, Docker, and CI/CD, allowing me to deploy, operate, and maintain the systems I build. This means you get a single engineer who can take ownership of a feature from database design all the way to production deployment and ongoing operations.
I graduated with First Class Honours in Computer Science and Engineering from the University of Moratuwa, Sri Lanka, and started writing code professionally at 18. I've shipped 20+ projects across eCommerce, SaaS platforms, real-time trading systems, bioinformatics tools, CRMs, and job marketplaces.
What I work with:
Frontend: React, Next.js, TypeScript, Tailwind CSS, Flutter (mobile)
Backend: Node.js, NestJS, Express, Java, Spring Boot
Databases: PostgreSQL, Redis, ClickHouse
Cloud & DevOps: AWS (EC2, ECS, S3, CloudFront, RDS), Docker, Kubernetes, Terraform, GitHub Actions
Observability: Prometheus, Grafana, OpenTelemetry
Integrations: Stripe, HubSpot, OpenAI, Anthropic API, Socket IO
Testing: Playwright, Jest
Recent work I'm proud of:
Built a real-time trading marketplace processing thousands of events per second using Node.js, PostgreSQL, Redis, Bull queues, Socket IO, and Stripe. Sub-50ms latency in production.
Built a HubSpot integration for a UK price-quote platform, automating the workflow between sales and client management.
Designed and built Spencio, a cross-platform mobile finance app, end to end — architecture, UI, and App Store/Play Store releases.
Set up a full homelab Kubernetes cluster with Flux CD GitOps, Grafana, Prometheus, and Cloudflare Tunnel running self-hosted services in production.
I work independently, communicate clearly, and deliver on time. I'm comfortable in mature codebases, fast-moving startups, and everything in between.
If you need someone who can ship real things, let's talk.
