A working demo and a system that survives production are two very different things. I build the second kind.
Over a decade of backend engineering and 70+ completed projects on Upwork. I run Datum Brain, a software and AI engineering company, so you get one senior engineer accountable end to end, with a team behind him when the work needs it. We ship Go microservices, data pipelines, and LLM systems for FinTech, SaaS, EdTech, and AdTech clients.
Recent work:
🛡 Real-time ad fraud detection (TrueAudience)
High-concurrency Go backend that scores ad traffic to catch bots before advertisers pay. 80M+ events, under 20ms decisions. Go, TimescaleDB, real-time pipelines.
🏦 Go microservices for an EMI and payments platform (Zolvat)
Ledger logic, payment flows, and service orchestration for an installment payments platform. Go, microservices, PostgreSQL.
🎥 WebRTC proctoring infrastructure (Meazure / Examity)
Real-time media and session orchestration for thousands of concurrent exam sessions at one of the largest US proctoring providers. Go, WebRTC, LiveKit, NATS.
📊 Big data pipeline optimization (Nike)
Cut processing time and compute cost on large PySpark workloads. PySpark, AWS.
📄 Document intelligence platform (Centrum AI)
OCR and RAG pipeline that turns unstructured documents into structured, queryable data with human review. Python, FastAPI, LangChain, RAG.
What I work with:
Backend: Go, Python, FastAPI, gRPC, REST, PostgreSQL, TimescaleDB, Redis, NATS, Kafka
Data: PySpark, ETL pipelines, data quality frameworks, AWS, GCP
Real-time: WebRTC, LiveKit, event streaming, high-concurrency systems
AI and LLM: LangChain, LangGraph, RAG, multi-agent systems, OpenAI, Claude, evals
Infra: Docker, Kubernetes, CI/CD, nginx
How I work:
I scope before I quote, so you know what you are getting and when.
I flag risks early instead of at the deadline.
Production-ready means tested, documented, monitored, and handed over properly.
Good fit if you need something that runs in production and not a proof of concept, you want one senior engineer accountable end to end, and you value clear communication and honest scoping. Not a fit if you are shopping purely on hourly rate, or the spec changes daily and nobody owns decisions.
If your backend needs to handle real load, or your data or AI work needs to go from demo to product, send me a message.

Most software projects fail for predictable reasons. Scope drifts, deadlines slide, communication collapses, and the build loses momentum. Whether this is your first project or your second attempt, you need an environment that prevents those failure points. Bee Techy (beetechy.com) exists for that purpose. My team takes ownership of the product and drives it to completion with clarity and speed.
You get a senior engineering team, not a single freelancer trying to manage every role at once. Delivery stays consistent. Communication stays direct. Complexity does not derail progress because the workflow is built to handle it.
Bee Techy (beetechy.com) is ranked in the top 1% of agencies on Upwork across more than ten categories. Enterprise clients including Microsoft, Amazon, HubSpot, and Shopify trust us. Clutch has recognized the agency with multiple awards across several industries for reliability and delivery quality. These signals matter because they confirm a consistent pattern: we finish what we start.
Execution is structured. Senior engineers write the code. A project manager drives the schedule. A separate QA team verifies every release. Projects begin within five business days. Throughput stays high because the environment is engineered for sustained output. AI assisted development increases volume without raising cost.
A Product Requirements Document is created at the start at no cost. It sets direction, eliminates ambiguity, and gives you a clear map of what will be built. The Bee Guarantee reduces your rate if the estimate is not met.
If you want your product built without drift or delays, this environment delivers it.
