D M Prasad Sampath Bandara D.

I am a senior Core Telecom and Value-Added Services (VAS) Engineer with 18+ years of experience, paired with 5+ years of experience architecting modern data engineering solutions. I specialize in solution design, development, integration, and troubleshooting for high-volume messaging, signaling infrastructure, and data analytics pipelines. I help MNOs, MVNOs, SMS Hubs, and aggregators optimize gateway routing, secure carrier interconnections, and transform raw network data into actionable business intelligence. Here is the exact technology stack and value I bring to your infrastructure: 🔹CORE TELECOM & VAS INFRASTRUCTURE (18+ Years) • Network Elements: Full-lifecycle deployment and optimization of SMSC, SMPP Gateway, MMSC, SMS firewall, USSD Gateways, and SMS Hub platforms. • Signaling & Protocols: Deep mastery of SS7, Sigtran (M3UA/SCTP), Diameter, SIP and SMPP application layers. • Interconnection & Billing: Designing resilient transit carrier links, resolving complex international routing anomalies, and auditing CDRs to stop billing leaks. • Protocol Diagnostics: Expert-level Wireshark packet trace analysis to resolve multi-link jitter, out-of-order SCTP delivery, and TCAP state-machine conflicts. • Next-Gen Network Design: Solution engineering and signaling diagnostics for 5G Core networks. 🔹 DATA ENGINEERING & ANALYTICS (5+ Years) • Pipeline Orchestration: Building and automating resilient ETL/ELT workflows using SSIS and Prefect. • Streaming & Ingestion: Architecting real-time, low-latency streaming layers with Apache Kafka to capture live network traffic events. • Database Engineering: Writing highly optimized SQL queries, indexing strategies, and schemas for massive time-series and relational databases. • Business Intelligence: Translating messy, high-volume signaling logs into automated PowerBI dashboards to monitor infrastructure KPIs and detect carrier fraud. • Modern data platforms: Experience in Databricks, Snowflake, and Microsoft Fabric 🔹 TELECOM-GRADE SOFTWARE ENGINEERING • Distributed Backends: Building robust, fault-tolerant, high-throughput backend applications using Erlang and Python. • Modern Frontends: Creating highly interactive, low-latency web portals and management consoles using React. • Database Ecosystems: Designing optimized schemas for Mnesia (Erlang-native), SQL Server, PostgreSQL, MariaDB, and MongoDB. • Cloud & DevOps: Containerizing workloads and managing orchestrations using Docker, Kubernetes, and automated CI/CD deployment pipelines. • Monitoring & Logging: Deploying enterprise observability stacks using Prometheus, Grafana, ElasticSearch, and Datadog to track system health. Whether you need a high-level solution architect to design your next messaging platform, a senior engineer to build a real-time distributed fault tolerance system backend and frontend or an observability expert to deploy a Datadog, Prometheus, Grafana monitoring stack for your live signaling streams, I deliver senior-tier execution. Let’s discuss how I can help optimize your SMS Hub, secure carrier interconnections, and scale high-throughput messaging platforms, while accelerating your data initiatives and bringing real-time observability to your backend systems.
