I'm Shubham — a senior full-stack engineer with 8 years of hands-on experience building enterprise SaaS products from zero to scale. I lead technical architecture and implementation on every project I take. My expertise: Over a 8-year track record, I've architected and shipped production systems at scale. I specialize in Django REST Framework backend architecture, Next.js full-stack development, real-time systems, and LLM integrations for data-heavy applications. I've led teams, managed complex migrations, and delivered mission-critical products under real constraints. Recent technical leadership: - Setera (3-year engagement): Led React frontend architecture for a custom enterprise SaaS. Designed the frontend system from scratch, mentored engineers on React patterns, and scaled the codebase to support thousands of concurrent users while maintaining code quality and performance. - Ailyze: Led the technical migration from Streamlit prototype to production Django SaaS with AI-powered data analysis. Rebuilt the data pipeline, integrated LLMs for qualitative research processing, implemented real-time data handling, and scaled the system from prototype to enterprise reliability. - SaaS Products: Architected and shipped booking systems, document signing platforms, and project management tools serving thousands of users. These engagements taught me how to design systems that scale, integrate third-party APIs cleanly (Stripe, etc.), and deliver user-facing excellence. What I deliver: ✅ Django REST Framework architecture, API design, and migrations ✅ Next.js full-stack SaaS applications with production maturity ✅ LLM integrations & AI-powered features (GPT, Claude, embeddings, etc.) ✅ Real-time systems, WebSocket implementation, data processing pipelines ✅ Third-party API integrations (Stripe, payment gateways, external services) ✅ Production scaling, database optimization, performance tuning ✅ React frontend architecture and complex state management ✅ Wagtail CMS implementation and customization How I work: - I lead hands-on on all projects and respond within 4 hours during IST-to-US overlap (5 PM IST to 3 AM IST). I'm transparent about scope, timelines, and constraints upfront. If something can't be built the way you envision, I'll tell you and suggest a better path. - I take on selective projects where I can contribute senior-level technical decision-making. If your scope grows, I can bring in additional resources from my team under my direct supervision — but you're working with me from day one. I'm a fit for: - Founders & product leads building SaaS products - Teams needing senior technical architecture (not just code output) - Projects where long-term technical quality matters more than speed-to-market I'm not a fit for: - "Build it cheap and fast" engagements - Projects where communication happens once a month - Scope creep without renegotiation Reply with your timeline and I'll respond within 4 hours.

Your GIS data is only as valuable as how fast your team can act on it. I build web-based geospatial applications that turn complex spatial data into clear, fast, decision-ready tools — accessible on any device, without heavy software or technical know-how. Whether you need an interactive mapping dashboard, a field data collection system, real-time spatial monitoring, spatial data processing and format conversion, or a custom GIS tool built around your team's actual workflow — the kind your people open every morning, not once and forget I specialize in translating geospatial complexity into clean, intuitive interfaces using tools like Leaflet, MapboxGL, PostGIS, QGIS, GDAL, and Python (GeoPandas, Shapely) — built to scale with your project, not against it. What sets my work apart isn't just technical output — it's that I ask the right questions upfront: Who is using this? What decision does it need to support? How does it fit into your team's existing workflow? That's how GIS projects go from "delivered" to genuinely adopted. If you have a GIS challenge that's been sitting unsolved — or spatial data your team isn't fully using yet — let's talk. Send me a message describing your project and I'll tell you honestly whether I'm the right fit.

In a previous life I worked investment banking in Sales and Trading for 4 years. Previous projects include: - Designing and building a client a booking engine to allow them to expand into the reservation and beauty treatment business (GCP, Python, Postgres, Redis and FastAPI). - Assisted a bottling company in expanding their tech capabilities by moving them from spreadsheets into the cloud and developing APIs to automate their business with other partners (Python, Postgres, AWS, FastAPI). - Refactored an employers crawling system to make it more efficient. Previously each data entity was crawled on a regular frequency, but the vast majority of entities very rarely changed leading to unnecessary crawling and resource use. The refactor took into account the changes in the data and how often they occurred to predict the next optimal time to crawl resulting in a 15% reduction in cloud costs (AWS, Postgres, NodeJS, Python, RabbitMQ). - Developed a streaming change data capture pipeline handling 50 million unique payloads per day resulting in a +15% reduction in total cloud costs while allowing live data to be available to customers (AWS, Python, NodeJS, RabbitMQ, Postgres, Snowflake, Airflow) - Created a data architecture to allow aggregation of geospatial time series for any possible geographic polygon across +20bn global data points in sub-second time (AWS, Clickhouse, Python, FastAPI, Postgres, Uber H3, Redis) - Created an autonomous on-demand Excel and PDF reporting system to allow a sales team to generate their own reports from data stores with no required input from developers (AWS, Python) - Developer multiple machine learning models running production including an age/gender classification for faces in photos (Python, Keras, GCP), entity resolution system combining tabular, text and image embeddings to deduplicate +30mm listings across multiple provider platforms (AWS, Python, PyTorch, RabbitMQ, Neo4j, Postgres)

I sit at the intersection of environmental science and geospatial engineering combining 9+ years of Earth system research with hands-on expertise in building production-grade GIS platforms, spatial data pipelines, and real-time environmental monitoring systems. 🌍 Geospatial Development & Web GIS: I design and deploy end-to-end geospatial solutions using industry-standard spatial infrastructure. My stack includes GeoServer and MapServer for OGC-compliant spatial services (WMS, WFS, WCS, WPS), ArcGIS Server / ArcGIS Enterprise with custom GP Services, and ArcGIS Online / Portal for enterprise deployments. On the frontend, I build dynamic, map-centric web applications using React.js and Node.js, integrating Leaflet, OpenLayers, ArcGIS JS API, and Mapbox GL JS to deliver polished, responsive interfaces. I consume and publish REST APIs and GeoJSON/OGC services fluently, and architect scalable spatial backends that connect databases (PostGIS, SDE), middleware, and live remote sensing feeds. 🛰️ Remote Sensing, GEE & Cloud Geospatial: I am deeply proficient in Google Earth Engine (GEE) — both the JavaScript and Python APIs — for large-scale satellite analysis, custom indices, time series extraction, and asset export workflows. I have worked extensively with Sentinel-1/2, Landsat, MODIS, MISR, and CloudSat imagery for flood mapping, LULC change detection, vegetation analysis, and atmospheric retrievals. I also leverage GEE API services to feed live computed outputs directly into web dashboards and geoportals. 🌡️ Climate, Atmospheric Science & Air Quality My research background spans climate forecasting, air quality assessment, and emissions analysis using model datasets including ERA5, MERRA-2, CAMS, and CHIRPS. I develop emission inventories, airshed-level management frameworks, hot-spot mapping workflows, and sector-specific energy demand forecasts. I have hands-on experience with ionospheric data, PM2.5 retrieval from aerosol constituents, and multi-variable atmospheric visualization pipelines. Programming & Data Engineering I code production-ready tools in Python, R, MATLAB, and JavaScript, with strong capabilities in spatial data mining, advanced visualization (Chart.js, Plotly, Matplotlib), and predictive modeling. I have a proven track record converting legacy Fortran, IDL, and Mathematica codebases into modern, maintainable Python frameworks — a rare but highly valuable skill for organizations modernizing their scientific infrastructure. Dashboards, Portals & Decision Support Systems I deliver custom geospatial dashboards and monitoring portals — from disaster management platforms and flood monitoring systems to air quality indices and renewable energy assessment tools — using ArcGIS Dashboards, ArcGIS Experience Builder, Power BI, and bespoke React-based interfaces. Every solution is built with real operational users in mind: clean UI, live data integration, and meaningful spatial storytelling. What sets me apart is the rare combination of scientific rigor and engineering execution. I don't just analyze environmental data — I build the systems that make that analysis accessible, scalable, and actionable for decision-makers on the ground.
