A vertically integrated practice: I architect the system, ship the code, and engineer autonomous, self-healing operating layers.
Custom finance, inventory, HR, and reservation architectures built on Spring Boot, PostgreSQL, and high-concurrency microservices with automated self-healing workflows.
Autonomous AI agents executing multi-step reasoning, RAG, tool calling, and MCP protocols (Claude, OpenAI, Gemini) to eliminate manual operational overhead.
Architecting quantum-resilient infrastructure against Q-Day and HNDL vectors using lattice-based Post-Quantum Cryptography (ML-KEM/FIPS 203) and Zero-Trust perimeters.
Migrating manual enterprise workflows to continuous, autonomous digital orchestration with deterministic auditing, edge synchronization, and real-time observability.

Domain-driven design, hybrid cloud-to-edge orchestration, microservices migration, and low-latency sovereign infrastructure designed for the 2026–2050 compute shift.
Algorithmic safety, context protocol governance, compute cost optimization, and enterprise workforce automation roadmaps.
Maintaining and enhancing a custom ERP system covering operations, HR, finance, inventory, and reservations. Developing new ERP features aligned with full business requirements. Automating stock, purchasing, billing, and daily processes to improve workflow efficiency and accuracy.
→ Automated core hotel billing, inventory, and HR workflows — eliminating manual overhead across operations.
Contributed to migrating legacy DTE systems into a modern microservices architecture. Built backend microservices using Spring Boot with Oracle DB integrations. Improved performance by optimizing large-scale database queries and worked with cross-functional teams to ensure smooth migration with minimal downtime.
→ Delivered legacy DTE to microservices migration with zero critical downtime incidents.
Developed fintech and e-commerce modules using Spring Boot, React, and PostgreSQL. Built a production digital wallet with Airwallex API integration using a microservices architecture. Improved scalability, performance, and UI/UX across multiple platforms through the full SDLC.
→ Delivered digital wallet platform with Airwallex integration and multiple fintech modules — live in production.

A strategic engineering matrix navigating the shift from generative tools to autonomous multi-agent orchestration, quantum-resilient cryptographic infrastructure, and deep physical-digital convergence.
Multi-step reasoning agents (Claude, GPT, Gemini) autonomously executing complex workflows, L1-L3 systems diagnostics, and tool use via Model Context Protocol (MCP).
Mitigating Q-Day and 'Harvest Now, Decrypt Later' (HNDL) threats via ML-KEM (FIPS 203) lattice-based key encapsulation and cryptographic agility.
Bifurcated architecture orchestrating hyper-scale AI training with localized, low-latency domain-specific edge inference across sovereign nodes.
Deterministic guardrails, continuous identity verification, RAG contextual integrity, and algorithmic auditing for autonomous enterprise pipelines.
Telemetry networks and orchestration layers for autonomous mobility, robotics collaboration, and high-throughput computational biology pipelines.
Mission-critical ERP cores with automated inventory, dynamic purchasing, and self-healing data pipelines scaled for enterprise concurrency.
Autonomous Systems & Workforce Transformation
By 2030, 50% of enterprise tasks will be machine-executed. I help leadership teams prepare their infrastructure for Agentic AI, Q-Day cryptographic migration, and sovereign edge computing.
“I had the distinct pleasure of mentoring Maneesha Gunawardhana during his BSc (Hons) in Software Engineering program. Maneesha is a deeply committed and highly capable individual with a robust understanding of core software development principles. I was particularly impressed by his dedication to continuous learning, exemplified by his proactive pursuit of certifications like the Google Certified Gemini Educator and Neo4j Certified Professional. He consistently demonstrated a sharp intellect, excellent problem-solving skills, and a professional maturity that sets him apart. Any team or organization would be fortunate to have him.”
