About
Senior Go / Backend Engineer and Project Lead with 10+ years of experience developing backend systems, distributed applications, cloud orchestration platforms, and telecommunications software.
Currently working as a Project Lead at Persistent Systems, contributing to enterprise network orchestration and SDN platforms. My professional experience spans backend services, distributed systems, 5G network functions, O-RAN technologies, and network automation across complex telecommunications environments.
My core expertise includes Go, C/C++, Python, microservices, network protocols, and cloud-native technologies. I enjoy solving complex engineering problems, evaluating architectural trade-offs, and developing reliable, maintainable software. I am particularly interested in senior engineering opportunities involving backend platforms, distributed systems, cloud infrastructure, and technical leadership.
High-performance services in Golang and C/C++ — microservices, gRPC, protocol stacks, and APIs built for scale and long-term maintainability.
Enterprise cloud orchestration, Cisco Crosswork NC, ORAN implementations, and 5G network functions from Abot to production SDN platforms.
Independent engineering work includes tollgate, an open-source Go rate-limiting library, and ZettaBridge, a discontinued trading infrastructure initiative retained as a technical case study.

Portfolio
Selected professional and independent engineering projects spanning backend systems, distributed architectures, network software, and developer tooling.
Go library implementing token bucket, fixed window and sliding window rate limiting behind a single interface, with net/http middleware. Sharded storage with per-shard locking, automatic eviction of idle entries, monotonic-clock arithmetic, and exact integer math in the sliding window. Zero dependencies, zero allocations per call at ~100ns. Published at pkg.go.dev with design decisions documented against benchmark evidence.
Open source · 2026Independently developed trading workflow infrastructure prototype exploring multi-tenant backend architecture, secure webhook ingestion, execution safeguards, broker integration workflows, and cloud-native deployment. Built using Go, Next.js, PostgreSQL, Redis, and AWS infrastructure. Commercial development was discontinued, and the project remains an engineering case study.
Jan 2026 — Jun 2026Contributing to Cisco Crosswork Network Controller, an enterprise SDN platform for IP transport network orchestration and automation. Work involves Go microservices on Kubernetes, intent-driven network automation, service lifecycle management, and integration across multivendor network environments. Responsibilities include coordinating engineering delivery, technical discussions, and implementation activities across project teams.
Jan 2024 — PresentORAN implementation for GNB-CU-CP, GNB-CU-UP, and GNB-DU with E1, E2, and F1-U interfaces. Centralized DB for 5G UDSF using Boost IO Services.
Apr 2022 — Dec 2023AMF, AUSF, and SMF NF development in Golang. Custom Manager NF with gRPC/REST services and a traffic generator for bandwidth, latency, and trace-route testing.
Apr 2021 — Mar 2022HTTP/2 interfaces for 5G network functions (AMF, AUSF, SMF) on the Abot 4G–5G test tool. Built a Python code generator that reads 3GPP YAML specs to auto-generate interface code, plus a C license client with AES-CBC encryption.
