Whether you need a cutting-edge AI-powered platform, an SEO-optimized site that ranks, or a custom web app built to scale, I have the tools, credentials, and experience to deliver. I go above and beyond for every client—ensuring clear communication, fast delivery, and solutions that move the needle for your business. Let's build something powerful together.

I build production-ready LLM chatbots and high-speed APIs that move business metrics. 15+ years in Python/FastAPI and data platforms. Led AI and backend at venture-backed and 🏅Fortune-500 products. 🏆 Launched LLM chatbot at GeoDB → new revenue vertical; deployed image generator to boost engagement. 🏆 Cut infra costs 8k→1k €/mo and halved annual budget 180k→90k by smart architecture & consolidation. 🏆 Built ETL pipelines (PyArrow/DuckDB) turning reports from days→minutes; scaled engine 1GB→4TB. 🏆 Hyperice (F500): WebSocket + FastAPI backend for group sessions → +15% engagement and $2M in subs revenue impact. What I deliver: 📦 LLM Chatbots & RAG: ChatGPT/Claude integration, LangChain/LangGraph, retrieval, tools, evals, guardrails. 📦 FastAPI Backends: Low-latency REST/WebSocket services, auth/RBAC, queues, testing, observability. 📦 Data Pipelines/ETL: Airflow jobs, PyArrow/DuckDB, PostgreSQL/MongoDB, analytics-ready models. 📦 Cost & Scale: Docker/AWS, async IO, caching, perf tuning, pragmatic infra that pays for itself. 🛠️ Stacks & keywords: Python, FastAPI, LangChain/LangGraph, OpenAI/Anthropic, RAG, Vector DBs, WebSockets, PyArrow, DuckDB, Airflow, PostgreSQL, MongoDB, AWS, Docker. How we start (low-risk): 🟢 48-hour Diagnostic – clarify use-cases, data, and constraints; mini-POC or architecture plan. 🟢 Milestone Plan – delivery roadmap with success metrics (latency, CTR, retention, cost). 🟢 Build & Ship – iterative releases with tests, dashboards, and handover docs. Results I optimize for: faster CX, higher conversion/retention, lower infra cost, clear analytics. 👉 Ready to move from idea to impact? Invite me with 2–3 lines about your users and goal. I’ll propose a concrete plan and timeline.

I build AI agents that connect to real business systems and do real work. Not chatbots that talk. Agents that query a live database, call tools, post the answer into Microsoft Teams, and survive messy JSON. Running in production today: a Copilot Studio agent used daily by a logistics dispatch team inside Teams, querying a live Azure SQL database with five tools, cross-table queries, and timestamped CSV export. Python agents on the Claude API with scheduled runs, auth, and state. An AS-400 to Dataverse migration of 100K+ rows with 50+ automated Power Automate flows. What I build: • Copilot Studio agents deployed to Microsoft Teams, grounded in your live data • Custom AI agents on the Claude and OpenAI APIs (Python) • MCP servers so Claude can use your systems as tools • Power Automate and Dataverse workflow automation built to survive failure and rerun safely • API, webhook, and JSON integrations, including OAuth and cross-tenant auth Microsoft certified: PL-600 (Solution Architect), PL-400 (Developer), PL-300, PL-100. Technical lead at a software company where these systems run in production daily. Based in Cleveland, Ohio, US Eastern. If you want an agent that ships and gets used, not a demo, let's talk.

I build production-grade GIS, mapping, routing, geocoding, and location-based systems using PostGIS, Django, GeoServer, QGIS, OSRM, Flutter, and modern cloud infrastructure. My strongest area is solving geospatial problems that need more than a basic map dashboard: route engines, reverse geocoding, distance matrices, GPS/location tracking, self-hosted map servers, spatial databases, mobile map apps, and remote-sensing workflows. As Head of GIS at PickMe, Sri Lanka’s leading real-time ride-hailing platform, I designed and delivered core geospatial systems including geocoder, reverse geocoder, POI search, road-network distance matrix, driver-passenger matching, fare modelling, and location-based dispatch support. These systems were built for real production usage with technologies such as PostGIS, OSRM, Tile38, Kafka, Redis, Python, Node.js, and Google Cloud Platform. Over 20+ years, I have delivered software for clients and companies in Sri Lanka, Japan, the USA, and the UAE. My work includes location-based navigation apps, municipal GIS asset-management systems, mapping platforms, AI-assisted SaaS applications, enterprise software, and mobile applications published on iOS and Android. I also run maplk, a self-hosted Sri Lanka vector tile, basemap, and routing server, and I have built real-time SaaS platforms with custom high-performance backend systems. I can help you with: * GIS web applications and dashboards * PostGIS database design, optimisation, and spatial queries * Routing, distance matrix, geocoding, and reverse geocoding * GeoDjango, Django REST APIs, and full-stack GIS platforms * GeoServer, WMS/WFS, QGIS, and ArcGIS-based solutions * GPS tracking, fleet/location systems, and real-time map apps * Flutter mobile mapping applications * Satellite/remote-sensing workflows using Sentinel data and Google Earth Engine * AWS/GCP deployment, Docker, and production handover I hold an M.Sc. in GIS & Remote Sensing and have published research on flood mapping and mitigation. If your project involves maps, routes, locations, spatial data, or remote sensing, I can take it from requirements to architecture, development, deployment, and documentation.
